Legit doc brown or marty mcfly over here trying to hit 88MPH, keep up the great work, I think what you've managed to hit is amazing with the bike, its the journey, not the end goal we are here for.
@@pentecost66 one thing is for sure, however different people do it, it needs to be done. Some people don't know that but every bike I've bought has needed it and badly. Most of the time that's all that was wrong with the bike.
Might be an ignition issue, sure the timing isnt off? Also if the exhaust i completely clocked, it should be cleaned. That also makes you loose a lot of power.
That could help a little, but that pipe is tuned for low end, not high end, so even if it's clean, it will only help the low end power. That bike will never do 80 mph, even when new. Top speed is about 60, if you're light enough, maybe 65 but I doubt it. Mine never went over 65, and it was new at the time.
dude, there is no way that thing ever did 85, I ran one for many years (had a speedometer). You have achieved top speed and should be proud. If somebody told you it could do over 8000 rpm under load in 5th gear, it's a fib...unless your screamin down a hill at 77mph, and you know damn well it would be a freak show to ride that thing over 80:)
Great series of vids. Check the exhaust is properly clean. A Two strokes power depends on the exhaust. Put air mix & jets back to factory settings. Clean and add 2 stroke oil to airfilter Check your oil pump settings (too much oil = too little fuel) Check your sprocket sizes are standard. If you still cannot reach 75+mph, take off the head & barrel. Check the condition of the piston now that you have been riding the bike. It may need a rebore. Remember, 75mph plus original speedo error is around 85mph... Thanks again for the vids I have enjoyed watching the TS come back to life.
Love your enthusiasm, and hell yes, clean up that trail. Who needs a track when you have that! Stage 2 reeds on my YZ250 made a huge difference, the crusty old ones may be creating a restriction.

Hi gold guy , I used to own a ts 125 and had same issue, if you’re exhaust is full of carbon you’ll have to replace it , a two stroke recycles unburnt fuel by the exhaust , an after market exhaust should do the trick, I used fresco exhausts . You should try talking the air filter off for a short run to see if it’s restricting it . Also you should go up from standard jet size 10 % with a pod filter or you’ll seize it on a long trip. You should change the reed valves also . And check your ignition system also . Hopefully this will help, love your videos by the way. Good luck.best regards, john Scott.
In my experience, if a bike feels better at 3/4 throttle than at full throttle, it’s often that the main jet is a little too large. Yours sounds like it’s bogging down. Do a plug chop on a full throttle run and compare it to a plug chop at 3/4 throttle. Remember that modern petrol isn’t the same as ‘70’s petrol so the stock jet settings are just a starting point. I also remember from the 70’s that that the exhaust needed cleaning fairly regularly, and if yours is a bit clogged that would make the mixture rich at full throttle. Final points, make sure the needle, needle jet and spray tube are actually right for that carb. The parts interchange with similar looking 4 stroke ones which wouldn’t work well but who knows what the DPO may have tried in the past :)

i fell like you guys are over looking the fact that he does the best with what he's got and he does a pretty damn good job. not everyone is a certified mechanic with the proper tools. get off your high horses lol. I think your videos are great. ignore these a-holes that forget they didn't know everything when they young. keep up the good work man
I love his videos too, I’m sure he has an adjustable spanner that would do the job if not the correct spanner. Jets are made of brass a soft material that is damaged easily, pliers will mutilate the outside surfaces and produce metallic swarf, not good in a carb or engine. Keep up the good work Gold Guy, your content is very interesting and enjoyable.
Try to get the original Air filter and also check if your exhaust is modifyed somehow. On my DT250 it made a HUGE difference to weld the original muffler back on. Way more power
he needs some aftermarket parts a 2 stroke is almost endless tunning possebileties hpi cilinderporting better pipe and tunning te carb to perfetion is real hard i can tell you and a good tunning can mean big power difrence sorry fore bad spelling
@@leepicgamer3320 It never will rev like an MX two stroke, completely different engine design, and different intended purpose. Those old TS185's were mild mannered trail bikes, that's all. Carb is tiny, intake is tiny, pipe is tuned for low end power.
Try cleaning out exhaust with a heat gun or torch. Then try running it without your homemade muffler it could be affecting back pressure? Also playing around with different air filters may help if you can get a stock one that would be best
My 1973 Kawasaki G4 100 is supposed to top out at 68. The only time I’ve got it to 66 was downhill with the wind. I drilled the idle jet abs extra .004”, and replaced the main 1075 with a 108, and running on double the oil it should (20:1 2-stroke Kawasaki racing oil)
I had a 75 model TS185 in 1978.Fantastic bike.Top speed is about 75mph on the clock.My mates brand new TS250 would only reach about 80mph. Off road my 185 kicked the 250s butt though.lol. What made you think they were good for 86mph? I also had the GT185 twin road bike & that would reach 85 just about.
I think in order to reach a higher top speed you might need to go up a tooth on the front sprocket or smaller on the rear. It sounds like its running great just running out of power.
Gold guy you just don’t give up keep at it are your crank case seals good and different sprocket sizes would definitely increase top speed last thing the lower the plug number the hotter it is. I think your vids are fantastic keep at it kid👍
you got a 2 stroke bike , they are VERY sensetive around the exhaustpipe , and i remember you fixing it , that is deff one of the issues , next is perhaps the bottom end gasket under the cylinder , try installing a thicker one to raise the exhaust duration time by moving the cylinder up 1/2mm it will give you more rpms tune the carbs and fix your exhaust !! your new to 2strokes so its a hard curve your in , but your doing it well !!.
Send the cylinder to someone who knows how to port it, get a custom made exhaust that matches the porting and get a CDI ignition if it doesn't have it. My Suzuki K50 moped with 86cc and only 4 gears does +70mph.
you may have a 125, carb or engine or exhaust, check the spark timing is the ignition coil getting hot?, check the float height in the carb not enough fuel and fuel flow from the tank, tank is not vacuming ? check the hole in the filler cap, slack in the throttle cable, is the slide going all the way up. good luck.
Dude love your videos. Very entertaining. I've got several old bike in different conditions and one I'd like to get going is a Yamaha 1975 MX125 that was literally sitting in a barn for many years in rough condition and untouched and I've had it for 10 years and never even kicked it over. Found your videos while looking for inspiration.
Back in '72 I had a 185 with a 4' trails tire in the back. The guy I bought if from had ported it. On the road, I used to drive that full throttle with my head down low on the handle bars. I never looked to see how fast I was going, I was just having so much fun driving fast. One night as I had my head down on the bars, I saw lights swirling in front of me on the road. I got off the handle bars & looked in the rear view mirror, a sheriff was right behind me. I pulled over, got off the bike, took my helmet off... he said..."what are you doing... you where going over 90MPH... " I said, this bike can't go that fast, because I was told 75MPH was tops... the sheriff told me to shut up... one aspect of my fine was I couldn't drive my bike for a week.
Adjust valves, point gap, timing. Install new plug, run full throttle for 30 seconds or so. Shut off bike, pull plug. You can tell whether it is rich or lean. Have you checked compression? Replaced rings? Lapped valves?
Your air screw only works with the pilot which is from idle to 1/8th throttle. Needle position will change mid range but also make the main richer or leaner. Each circlip height makes up for about 7 main jet sizes so keep that in mind when you play with needle heights. Your bike will also make more power running slightly rich than slightly to lean if it's not tuned perfect either. There's no harm in running slightly rich where being to lean can cause bearings to fail and your piston to seize, more so if it's pre mix. You should cook all the carbon out of the exhaust and silencer as others have said. If your silencer is the type to have baffle packing you will loose low end and mid range power without any. Good luck with tuning it, looking forward to seeing it on more trails so clean them up!
Lol.. Running rich won't cause it to run hot nor will it cause a blockage. I said slightly rich is better than slightly to lean. At most it will get a bit of carbon build up, would take yrs to block an exhaust port even running far to rich. Guess you've never played with jets before? Excessive heat in a 2t is caused from being overly lean and a lack of lubrication
And are you a 100 percent the top speed of those stock was 85mph? 65 seems absolutely amazing for such an old rig man I think you've done perfect on it
I've seen several different top speeds listed between 70 and 86mph. These bikes were produced over a long period of time so I wouldn't be surprised if all of them are correct.
No they will do 135 to 140 kph everyday stock, also at that speed they are revving there tits off. It was my first bike so I am aware his bike is running like crap, may be exhaust carboned up.
Ts185 does 86 mph stock. My ts 185 has performance reeds and does 75mph no problem and that's with a bigger rear sprocket. 69 mphfor the ts100 crazy but true. My son hits 65 on him, but that's with performance reeds. It's a 1980 ts 100, thats 42 years old. Mine is a 1981 ts185. Both bikes still using original oil injectors . Fun old bikes and perfect for a father son resto. My 16 year old son has learned how to do so much more than I ever expected. I cherish these days with him and wouldn't trade them for the world.
After trying everything in carb then it’s not a carb issue, check with it’s clutch work since if it’s accelerating more and low power means I am little sure it’s clutch part issue. I hope this will help.
Hey G.G. Nice video. I think you a restrictive air flow when you give it full throttle. Maybe caused by you airfilter/airscrew. What is the color on the sparkplug after your trip? If it black it could be because you exhaust is to restrive. Hope you find the fault.
I live in a Japanese city and I miss Australia, but to see the beautiful and natural mix of green, trees, shrubs, trails, yards, the blue sky even to imagine the smells..it looks so gorgeous..what part of the states is this?
What about a sprocket change? Go down two teeth in the rear and up one in the front and see how much the speed increases! That's what I've had luck with on the dirt bikes I own. It makes them much more road friendly. Good luck man!!
My 72 185 top speed is 70mph If your sprockets are stock Check throttle cable make sure its pulling slide all the way up but not past wide open If it goes past it will slow you down. Quick check take it for a ride Let off throttle a little bit while wide open if it speeds up your cables out of adjustment
You can get an OKO carb for it for about $50 on eBay. You also need to change the gearing for 80mph. It will do it, but you need a much smaller rear sprocket
Check the engine stamp may have 125 in there, maybe throttle slide is not fully rising, no slack in the cable. Remove exhaust and have a look in the exhaust port to see if coked up or restricted with a washer. Remover air cleaner, also check float bowl petrol height. Would check the timing on the ignition side with a strobe and the points gap. Are you getting 5 gears not just reving it out in 4 th check gearbox oil level as well. Last thing is ignition coil getting hot after a few minutes of running it could be on the way out.
Thats about right for one of these,ignore the specs from factory,try removing head gasket for higher compression ,remove gasket tighten down head remove plug then kick it over to see if the piston doesn't hit the head,remove air filter and cover with an old stocking and lay down full throttle,should take you over 70,tyre size in height and weight effect top speed also.If she feels like it hits top speed quick and holds try one tooth bigger on the front sprocket.
So many variables, i think Suzuki measured the top speed going down hill with the wind behind them!, i think 70 mph isn't far off. i think you need to find out what it's revving to first off, that'll give you some idea if it's reaching peak revs, is the gearing stock? me i'd fit the original air box and filter, put the jetting back to stock, strokes and pod filters don't mix well. bike looks great.
Also, try a plug chop. (Top gear full speed then switch off the ignition) Pull the plug and check the colour. It’ll give you an idea of where your at with the fueling
Install a exhaust temp gauge so we can really tweak it. It doesn't get enough gas at top end because the exhaust pipe is restricted and the idle jet is very integral in top end shenanigans...the lack of torque at top end is how aluminum pistons melt. Wait until November when all the trail brush dies.
Oh and I forgot. I've ridden a Suzuki AX100, which is 100cc two stroke, and out of the box the thing was able to reach 60 mph. With a little taller gearing I managed to cruise at 65 mph 250 miles of a roadie. That thing should go a lot faster with taller gearing. No need to make it lean to the point where it is about to seize the engine for it to go fast. All you'll end up doing is sacrificing your acceleration (even more than with the taller gearing) and reliability for a couple extra mph. Now I believe there's another thing we might be overlooking here. Is the timing advance at spec? I believe all those "cheap" (alas great) bikes were not all set exactly the same in regards to ignition timing. That's why the discrepancy of the final speeds and power the same make and model can have on two different bikes. I'm eager to see a video on it as I'm about to get myself a TS185. What's your thoughts on the bike btw?
You could also try cleaning your exhaust expansion chamber. Or what they considered a expansion chamber during those years. Best easy way put it in a barbecue or on the ground pile up large bag of charcoal around the pipe and light it on fire let the charcoal do its job. It'll cook all the carbon turn it into Ash
Do the reeds in the carb get old over time? Maybe be worth changing them, also is air is the air filter standard I can't remember if not go back to standard. CLEAN UP THE TRAILS. loving your work proper bike DIY, all the best from the UK.
I had a 72 TS185 when I was in high school. I don't believe the 80 mph top speed is realistic. Mine would go an "indicated" 70 mph. I weighed 150 - 170lbs at the time. Perhaps putting a stock speedo on would read different? Anyway, there are 2 items on your bike that are NOT stock, (the silencer and the air filter). I know, I know, that foam filter is supposed to be better than the stock airbox/filter setup but it may not be. With respect to your observation that, backing off on the throttle slightly offers more power, would suggest that your still rich on top. Try raising the clip to the highest groove on the needle. Moving the clip up moves the needle down into the main jet and reduces the amount of fuel it passes, (makes it leaner or less rich at top speed).
Sprocket size front and back make sure they are factory sizes.. make sure your exhaust is clear, you can check it by taking off your muffler at the end of your exhaust system and then go for a spin you will gain a few miles an hour, if it gains more than 5 mph its because your muffler is in need of cleaning. Also check your timing marks make sure they are aligned. If you put boysen reeds you will gain at least 15% more power, you should definitely feel a difference. the steel reeds that are factory hold it back for sure. If you don't have the money for reeds, then I just flip your existing reeds over. Performance reeds are what I put on my TS185. I'm hitting up to 77 or 78 mph. And make sure you tuck down, when going for top speed. Wind resistance will slow you down. Good luck keemosaby. My spelling is pathetic. My son has a 1980ts100 it does 65 it supposedly does a factory 69 mph. Get to work, never give up, walk away when frustrated and calm yourself, the get your ass back to work. You can do it Young man. Now get your ass back to work. Lol ( And you're welcome )
This is all nice and good, but will you please go with premixed fuel (40:1) and a rejetted carburetor? I personally would like to see that and think it would make good content and piles more power
When I was riding stuff around 35 yrs ago like this they were running on 2 and 3 star petrol , or as you call it gas, here in the uk 🇬🇧, which has a much higher octane as well as the petrol was leaded ,, so guess that would affect it ? Maybe cheers Shane uk 🇬🇧
I was around those type of bikes as a kid. I had a 125 Yamaha enduro. Mine topped out at about 55 or so. A 185 probably tops out at around 65 or so. It just isn't true that you are going to get 86 mph out of a bike like that. That's crazy. Your bike is running well. Just enjoy it. And the literature from the manufacturer is often wrong. The Japanese guy who wrote that was obviously drunk.
@GoldGuy yea I have no idea man what could be causing your bike too not reach it's top speed. Seems like you have tried pretty much everything. Could it be because you have an aftermarket air filter? How is the condition of the wheel bearings and suspension?
I am sure the 86 MPH "spec" is untrue. 68-72 MPH is a much more likely estimate. Playing with the gearing would give you a better chance of achieving a higher top speed. Are the counter shaft and rear sprocket the correct sizes as Suzuki intended? Good luck breaking the sound barrier.
I had the first model out. Nice orange paint. looked great. ran great but. 59.9 miles per hour. Above that, it started to hack like it had a rev limiter. Friends liked mine, great bottom end tourque off road. Theirs were not as good on the bottom but easily did over 59.9 MPH. Got stuck behind a VW van and just about bought the farm. He would speed up on straights and slow down on corners. after 1/2 hour of this, I tried to pass. Semi coming toward us. Guess I made it but. Took it to dealer and they could do nothing. It's not carb, gotta be in the ignition.
clean the pipe out by pouring gas in it and lighting it up. soot and whatever should pour out...ignition or maybe a bit too rich still, try testing by turning off the petcock while riding full throttle and see if the speed increases.
You should check spark plug on full throttle.Drive bike al least 500m on full throttle and stop immediately and check spark color and find oem air box.Oem main jet is 130 pilot jet 25 and pilot air screw 1 1/2.
rear tire stock size or wore out? i would say the estimated top speed is over-estimated, 65mph is really fast for that being from 1977 lol if you absolutely have to hit 80 you could change the gearing, go bigger on the front, one tooth in the front is around 3 in the rear, wont make a huge difference though tbh
you have weak compresion, change segments on piston ar the whole set.... second is the timing... definetly needs adjusting with a measuring tool not by hand... third is still the carburator, you need to reduce a little the fuel so it has more air... hope it helps ...
De coke the exhaust check the igniting timing/ points and the gearing is probably the problem as it sounds like it's revving out fine. Maybe they never actually hit 80mph from stock
I would try the next smaller size of main jet. Nothing to loose by doing that, eh? Wouldn´t Change sprockets to get faster on a trails bike, because this means loosing torque. Thumbs up and go on like you did. P.S.: I will try out the screw driver droping method. lol.
get a better gases flow with cleaning exhaust, maybe polish piston and head, grind down sharp edges between carburetter and cylinder, if there are some. Also you need to adjust ignition timing to get the best performance in high RPM.
Nice work Gold Guy ... check the original size of front and rear sprocket. I think its been geared for low end not hi speeds . Good luck keep em coming dude.
i have a similar issue with my 73, although im not after the nuber 86, power past 3/4 throttle dies out, i cant use fith gear because it completely bogs out.
Maybe your homemade muffler is the problem, maybe it changed the pressure, 2 strokes need to have the right pressure the run great or adjustment on the mixer screw, try give it more air
Maybe its got to do with your muffler? is the wool wrapped tight enough, otherwise it would eat power. is the diameter too small or too big? but anyways, all of those old bikes run differently, my Yamaha dt125 also runs slower than it could and i dont know why. keep it up!

Please take this grain of salt as guidance on internet wisdom and find good resources for basic (carb -intake )education by yourself as a basis.

i fell like you guys are over looking the fact that he does the best with what he's got and he does a pretty damn good job. not everyone is a certified mechanic with the proper tools. get off your high horses lol. I think your videos are great. ignore these a-holes that forget they didn't know everything when they young. keep up the good work man
I love his videos too, I’m sure he has an adjustable spanner that would do the job if not the correct spanner. Jets are made of brass a soft material that is damaged easily, pliers will mutilate the outside surfaces and produce metallic swarf, not good in a carb or engine. Keep up the good work Gold Guy, your content is very interesting and enjoyable.
Great job on the TS185. Always enjoy watching your videos
I wonder what the rpm's are and what the redline is. I think 64 is respectable for a 185cc 50 year old bike.
Try to get the original Air filter and also check if your exhaust is modifyed somehow. On my DT250 it made a HUGE difference to weld the original muffler back on. Way more power
Feels good to see some trail riding on this old bike. Hopefully I’ll be able to get some footage of me on mine soon
Exhaust clogged up .. Ignition timing a little off .. maybe.. Is final drive stock? EDIT: Cean up the trails dude!!
he needs some aftermarket parts a 2 stroke is almost endless tunning possebileties hpi cilinderporting better pipe and tunning te carb to perfetion is real hard i can tell you and a good tunning can mean big power difrence sorry fore bad spelling
That's what i was thinking it doesn't rev like a 2-stroke should.
@@leepicgamer3320 haha 4 stroke rpm on a 2 stroke bike
@@leepicgamer3320 It never will rev like an MX two stroke, completely different engine design, and different intended purpose. Those old TS185's were mild mannered trail bikes, that's all. Carb is tiny, intake is tiny, pipe is tuned for low end power.
@@trevorjameson3213 yeah but i have friends who own Suzuki PV bikes from the 80's. Those bikes rev pretty good with bit of tuning.
Try cleaning out exhaust with a heat gun or torch. Then try running it without your homemade muffler it could be affecting back pressure? Also playing around with different air filters may help if you can get a stock one that would be best
My 1973 Kawasaki G4 100 is supposed to top out at 68. The only time I’ve got it to 66 was downhill with the wind. I drilled the idle jet abs extra .004”, and replaced the main 1075 with a 108, and running on double the oil it should (20:1 2-stroke Kawasaki racing oil)
I had a 75 model TS185 in 1978.Fantastic bike.Top speed is about 75mph on the clock.My mates brand new TS250 would only reach about 80mph. Off road my 185 kicked the 250s butt though.lol. What made you think they were good for 86mph? I also had the GT185 twin road bike & that would reach 85 just about.
I think in order to reach a higher top speed you might need to go up a tooth on the front sprocket or smaller on the rear. It sounds like its running great just running out of power.
Gold guy you just don’t give up keep at it are your crank case seals good and different sprocket sizes would definitely increase top speed last thing the lower the plug number the hotter it is. I think your vids are fantastic keep at it kid👍
you got a 2 stroke bike , they are VERY sensetive around the exhaustpipe , and i remember you fixing it , that is deff one of the issues , next is perhaps the bottom end gasket under the cylinder , try installing a thicker one to raise the exhaust duration time by moving the cylinder up 1/2mm it will give you more rpms tune the carbs and fix your exhaust !! your new to 2strokes so its a hard curve your in , but your doing it well !!.
Great job. keep this up. It is giving me inspiration to get started on my project. I am about to re-build an 89 DT200r. Should be a lot of fun. :)
Send the cylinder to someone who knows how to port it, get a custom made exhaust that matches the porting and get a CDI ignition if it doesn't have it. My Suzuki K50 moped with 86cc and only 4 gears does +70mph.
you may have a 125, carb or engine or exhaust, check the spark timing is the ignition coil getting hot?, check the float height in the carb not enough fuel and fuel flow from the tank, tank is not vacuming ? check the hole in the filler cap, slack in the throttle cable, is the slide going all the way up. good luck.
Dude love your videos. Very entertaining. I've got several old bike in different conditions and one I'd like to get going is a Yamaha 1975 MX125 that was literally sitting in a barn for many years in rough condition and untouched and I've had it for 10 years and never even kicked it over. Found your videos while looking for inspiration.
Back in '72 I had a 185 with a 4' trails tire in the back. The guy I bought if from had ported it. On the road, I used to drive that full throttle with my head down low on the handle bars. I never looked to see how fast I was going, I was just having so much fun driving fast. One night as I had my head down on the bars, I saw lights swirling in front of me on the road. I got off the handle bars & looked in the rear view mirror, a sheriff was right behind me. I pulled over, got off the bike, took my helmet off... he said..."what are you doing... you where going over 90MPH... " I said, this bike can't go that fast, because I was told 75MPH was tops... the sheriff told me to shut up... one aspect of my fine was I couldn't drive my bike for a week.
Adjust valves, point gap, timing. Install new plug, run full throttle for 30 seconds or so. Shut off bike, pull plug. You can tell whether it is rich or lean. Have you checked compression? Replaced rings? Lapped valves?
It’s a two stroke… no valves
Your air screw only works with the pilot which is from idle to 1/8th throttle.
Needle position will change mid range but also make the main richer or leaner.
Each circlip height makes up for about 7 main jet sizes so keep that in mind when you play with needle heights.
Your bike will also make more power running slightly rich than slightly to lean if it's not tuned perfect either.
There's no harm in running slightly rich where being to lean can cause bearings to fail and your piston to seize, more so if it's pre mix.
You should cook all the carbon out of the exhaust and silencer as others have said.
If your silencer is the type to have baffle packing you will loose low end and mid range power without any.
Good luck with tuning it, looking forward to seeing it on more trails so clean them up!
Lol.. Running rich won't cause it to run hot nor will it cause a blockage. I said slightly rich is better than slightly to lean. At most it will get a bit of carbon build up, would take yrs to block an exhaust port even running far to rich. Guess you've never played with jets before? Excessive heat in a 2t is caused from being overly lean and a lack of lubrication
I had a 1973 from new. I put a chamber on it to keep up with the 400 Suzuki. I really loved that bike
And are you a 100 percent the top speed of those stock was 85mph? 65 seems absolutely amazing for such an old rig man I think you've done perfect on it
I can do 65mph on my ke 100. I guess the TS at least should reach 75mph
I've seen several different top speeds listed between 70 and 86mph. These bikes were produced over a long period of time so I wouldn't be surprised if all of them are correct.
No they will do 135 to 140 kph everyday stock, also at that speed they are revving there tits off. It was my first bike so I am aware his bike is running like crap, may be exhaust carboned up.
My 71 ts90 can hit 55 at least, probably 60. So I'd imagine this bike can do 70 at least
Ts185 does 86 mph stock. My ts 185 has performance reeds and does 75mph no problem and that's with a bigger rear sprocket. 69 mphfor the ts100 crazy but true. My son hits 65 on him, but that's with performance reeds. It's a 1980 ts 100, thats 42 years old. Mine is a 1981 ts185. Both bikes still using original oil injectors . Fun old bikes and perfect for a father son resto. My 16 year old son has learned how to do so much more than I ever expected. I cherish these days with him and wouldn't trade them for the world.
YES!! Clean up them trails..
After trying everything in carb then it’s not a carb issue, check with it’s clutch work since if it’s accelerating more and low power means I am little sure it’s clutch part issue. I hope this will help.
I had one of these exact bikes. I love watching these videos
Hey G.G. Nice video. I think you a restrictive air flow when you give it full throttle. Maybe caused by you airfilter/airscrew.
What is the color on the sparkplug after your trip? If it black it could be because you exhaust is to restrive.
Hope you find the fault.
NGK spark plugs and heat range go cooler the higher the number.. so the bpr7es is colder the the 6es..
Try with cleaning the carbon build up on the exhaust and a smaller rear sprocket
Good job brother. Long wait for the resto well worth the effort.
I live in a Japanese city and I miss Australia, but to see the beautiful and natural mix of green, trees, shrubs, trails, yards, the blue sky even to imagine the smells..it looks so gorgeous..what part of the states is this?
What about a sprocket change? Go down two teeth in the rear and up one in the front and see how much the speed increases! That's what I've had luck with on the dirt bikes I own. It makes them much more road friendly. Good luck man!!
My 72 185 top speed is 70mph
If your sprockets are stock
Check throttle cable make sure its pulling slide all the way up but not past wide open
If it goes past it will slow you down.
Quick check take it for a ride
Let off throttle a little bit while wide open if it speeds up your cables out of adjustment
I was thinking the same thing.
You can get an OKO carb for it for about $50 on eBay. You also need to change the gearing for 80mph. It will do it, but you need a much smaller rear sprocket
Check the engine stamp may have 125 in there, maybe throttle slide is not fully rising, no slack in the cable. Remove exhaust and have a look in the exhaust port to see if coked up or restricted with a washer. Remover air cleaner, also check float bowl petrol height. Would check the timing on the ignition side with a strobe and the points gap. Are you getting 5 gears not just reving it out in 4 th check gearbox oil level as well. Last thing is ignition coil getting hot after a few minutes of running it could be on the way out.
Thats about right for one of these,ignore the specs from factory,try removing head gasket for higher compression ,remove gasket tighten down head remove plug then kick it over to see if the piston doesn't hit the head,remove air filter and cover with an old stocking and lay down full throttle,should take you over 70,tyre size in height and weight effect top speed also.If she feels like it hits top speed quick and holds try one tooth bigger on the front sprocket.
So many variables, i think Suzuki measured the top speed going down hill with the wind behind them!, i think 70 mph isn't far off. i think you need to find out what it's revving to first off, that'll give you some idea if it's reaching peak revs, is the gearing stock? me i'd fit the original air box and filter, put the jetting back to stock, strokes and pod filters don't mix well. bike looks great.
Also, try a plug chop.
(Top gear full speed then switch off the ignition)
Pull the plug and check the colour. It’ll give you an idea of where your at with the fueling
Install a exhaust temp gauge so we can really tweak it.
It doesn't get enough gas at top end because the exhaust pipe is restricted and the idle jet is very integral in top end shenanigans...the lack of torque at top end is how aluminum pistons melt.
Wait until November when all the trail brush dies.
Oh and I forgot. I've ridden a Suzuki AX100, which is 100cc two stroke, and out of the box the thing was able to reach 60 mph. With a little taller gearing I managed to cruise at 65 mph 250 miles of a roadie. That thing should go a lot faster with taller gearing. No need to make it lean to the point where it is about to seize the engine for it to go fast. All you'll end up doing is sacrificing your acceleration (even more than with the taller gearing) and reliability for a couple extra mph. Now I believe there's another thing we might be overlooking here. Is the timing advance at spec? I believe all those "cheap" (alas great) bikes were not all set exactly the same in regards to ignition timing. That's why the discrepancy of the final speeds and power the same make and model can have on two different bikes.
I'm eager to see a video on it as I'm about to get myself a TS185. What's your thoughts on the bike btw?
You could also try cleaning your exhaust expansion chamber. Or what they considered a expansion chamber during those years. Best easy way put it in a barbecue or on the ground pile up large bag of charcoal around the pipe and light it on fire let the charcoal do its job. It'll cook all the carbon turn it into Ash
Maybe look into timing adjustment and make sure valves are properly adjusted. Good luck, I hope you can figure the top-end out, it looks pretty close.
Do the reeds in the carb get old over time? Maybe be worth changing them, also is air is the air filter standard I can't remember if not go back to standard. CLEAN UP THE TRAILS. loving your work proper bike DIY, all the best from the UK.
You gotta clean up the trails!
CLEAN UP THEM TRAILS!!!!!!!😂 honestly I think it would make a good video
I had a 72 TS185 when I was in high school. I don't believe the 80 mph top speed is realistic. Mine would go an "indicated" 70 mph. I weighed 150 - 170lbs at the time. Perhaps putting a stock speedo on would read different? Anyway, there are 2 items on your bike that are NOT stock, (the silencer and the air filter). I know, I know, that foam filter is supposed to be better than the stock airbox/filter setup but it may not be. With respect to your observation that, backing off on the throttle slightly offers more power, would suggest that your still rich on top. Try raising the clip to the highest groove on the needle. Moving the clip up moves the needle down into the main jet and reduces the amount of fuel it passes, (makes it leaner or less rich at top speed).
Sprocket size front and back make sure they are factory sizes.. make sure your exhaust is clear, you can check it by taking off your muffler at the end of your exhaust system and then go for a spin you will gain a few miles an hour, if it gains more than 5 mph its because your muffler is in need of cleaning. Also check your timing marks make sure they are aligned. If you put boysen reeds you will gain at least 15% more power, you should definitely feel a difference. the steel reeds that are factory hold it back for sure. If you don't have the money for reeds, then I just flip your existing reeds over. Performance reeds are what I put on my TS185. I'm hitting up to 77 or 78 mph. And make sure you tuck down, when going for top speed. Wind resistance will slow you down.
Good luck keemosaby. My spelling is pathetic. My son has a 1980ts100 it does 65 it supposedly does a factory 69 mph. Get to work, never give up, walk away when frustrated and calm yourself, the get your ass back to work. You can do it Young man. Now get your ass back to work. Lol
( And you're welcome )
Clean up those trails. I'd love to have that space to ride just next to my house
This is all nice and good, but will you please go with premixed fuel (40:1) and a rejetted carburetor? I personally would like to see that and think it would make good content and piles more power
CDI box might cause such problems. I once got a problem that my 125 wouldn't go over 40mph, changed the cdi box, problem fixed.
When I was riding stuff around 35 yrs ago like this they were running on 2 and 3 star petrol , or as you call it gas, here in the uk 🇬🇧, which has a much higher octane as well as the petrol was leaded ,, so guess that would affect it ? Maybe cheers Shane uk 🇬🇧
Hi mate. She looks great. What rear mudguards are you running?
I was around those type of bikes as a kid. I had a 125 Yamaha enduro. Mine topped out at about 55 or so. A 185 probably tops out at around 65 or so. It just isn't true that you are going to get 86 mph out of a bike like that. That's crazy. Your bike is running well. Just enjoy it. And the literature from the manufacturer is often wrong. The Japanese guy who wrote that was obviously drunk.
@GoldGuy yea I have no idea man what could be causing your bike too not reach it's top speed. Seems like you have tried pretty much everything. Could it be because you have an aftermarket air filter? How is the condition of the wheel bearings and suspension?
Man, drilling out a main jet, really no wonder it run's like crap !
Clean up them trails and ride the 4 fitty! Lets go! Your f-in videos kill me. Keep up the great work!
Have you tried changing the sprockets to alter the gearing.ignition timing is something to check and see if it is a 185 engine and not a 125
@GoldGuy dude I got a 2005 Suzuki Dr-z125 it's a great trail bike I've hit 53.5 mph on it So far.
Perhaps you could adjust the timing to (I can’t remember if it’s before or after top dead centre) to give an extra boost to the piston
I am sure the 86 MPH "spec" is untrue. 68-72 MPH is a much more likely estimate. Playing with the gearing would give you a better chance of achieving a higher top speed. Are the counter shaft and rear sprocket the correct sizes as Suzuki intended? Good luck breaking the sound barrier.
I had the first model out. Nice orange paint. looked great. ran great but. 59.9 miles per hour. Above that, it started to hack like it had a rev limiter. Friends liked mine, great bottom end tourque off road. Theirs were not as good on the bottom but easily did over 59.9 MPH. Got stuck behind a VW van and just about bought the farm. He would speed up on straights and slow down on corners. after 1/2 hour of this, I tried to pass. Semi coming toward us. Guess I made it but. Took it to dealer and they could do nothing. It's not carb, gotta be in the ignition.
clean the pipe out by pouring gas in it and lighting it up. soot and whatever should pour out...ignition or maybe a bit too rich still, try testing by turning off the petcock while riding full throttle and see if the speed increases.
You should check spark plug on full throttle.Drive bike al least 500m on full throttle and stop immediately and check spark color and find oem air box.Oem main jet is 130 pilot jet 25 and pilot air screw 1 1/2.
The Suzuki ER185 did 70 mph, in top gear the rpm matched the mph, it went up to 7000rpm, throttle wheelies in 3rd gear.
Cool vid. It's great that you fix these bikes, such a sense of achievement.
rear tire stock size or wore out? i would say the estimated top speed is over-estimated, 65mph is really fast for that being from 1977 lol
if you absolutely have to hit 80 you could change the gearing, go bigger on the front, one tooth in the front is around 3 in the rear, wont make a huge difference though tbh
you have weak compresion, change segments on piston ar the whole set.... second is the timing... definetly needs adjusting with a measuring tool not by hand... third is still the carburator, you need to reduce a little the fuel so it has more air... hope it helps ...
De coke the exhaust check the igniting timing/ points and the gearing is probably the problem as it sounds like it's revving out fine. Maybe they never actually hit 80mph from stock
Love the vid iv got one in the uk and mine as never gone over 65 . Great work gold guy
Sport air filter may cause the lose of top speed and the muffler that you made may too.
My thoughts :)
But awesome build!
I would try the next smaller size of main jet. Nothing to loose by doing that, eh? Wouldn´t Change sprockets to get faster on a trails bike, because this means loosing torque. Thumbs up and go on like you did. P.S.: I will try out the screw driver droping method. lol.
get a better gases flow with cleaning exhaust, maybe polish piston and head, grind down sharp edges between carburetter and cylinder, if there are some. Also you need to adjust ignition timing to get the best performance in high RPM.
I got my 74 to 65 the other day shit was zooming there such fun bikes
Hey I think I remember you doing a carb tuning series on this bike what pilot sizes did you end up using with your pod filter?
go down a tooth on front sprocket, then use higher octane fuel, yes clean those trails lol. I luv that bike too.
Nice work Gold Guy ... check the original size of front and rear sprocket. I think its been geared for low end not hi speeds . Good luck keep em coming dude.
Pretty sure the bolt on the bottom of the fuel bowl allows you access to the jets without taking the bowl off
If you're running an oiled air filter you could have too much oil in it try cleaning out the air filter and oiling it with much less oil.
I have a rear fender and parts if you want. Like speedo and front brake drum with speedo.
you"re driving like most people do in GTA ! xD
i have a similar issue with my 73, although im not after the nuber 86, power past 3/4 throttle dies out, i cant use fith gear because it completely bogs out.
Maybe your homemade muffler is the problem, maybe it changed the pressure, 2 strokes need to have the right pressure the run great or adjustment on the mixer screw, try give it more air
Maybe its got to do with your muffler? is the wool wrapped tight enough, otherwise it would eat power.
is the diameter too small or too big?
but anyways, all of those old bikes run differently, my Yamaha dt125 also runs slower than it could and i dont know why.
