Thanks, i´m a motorcycle mechanic and i like a lot your sense of persistence when you do things you don´t know. Congratulation for the genius work you develop in your man cave! Lots of courage is my desire here from Portugal. I follow your channel .
A simple thing that I noticed. Some of those brass fittings that you left in the carburetor are the jets. The jets are usually removed and cleaned while removed from the carburetor. Try pulling some out and inspecting that they aren't clogged and all the tiny holes are clear.
Your best bet would be to check the compression of that motor. If the test looks good then you should get some new plugs and if required new ignition coils. If the compression test does not look good find if your problem is the headgasket or at worse case scenario if your block is cracked. Also you should check the piston rings of the engine - which is an easy test - : put your finger over the crankcase ventilation port and crank the engine. If you can feel barely any pressure you are probably fine but if you feel quite a good bit of pressure then you should investigate those rings. If I where you I would not spend money before doing these tests. Most of these problems - except the cracked block - are easy more or less to fix at home with a few hand tools and a bunch of time and patience. I really hope that you manage to get this bike started.
Dont waste your time bro. You had oil in the radiator. That means that u have a bad head gasket. Bad head gaskets cause poor compression and that is part of the starting issue. I wish that u would listen to your subscribers once in a while.
Hope This Works 'Our Homestead' your definetly right my friends truck did the same but he probably won't read your comment so he will be struggling awhile
how about he spends the money on service manual. I have never seen him open one up. Part of a learning experience is ACTUALLY LISTENING to other people and allowing them to help.!!!!!!!!!!
I would start with a compression test on all cylinders, there is no point in spending time and money on any parts until you know the condition of the engine.
I did a full restomod project on an 87 cbr600f1 hurricane. It was a cool bike to work on and it was one that i spent weeks working on and spending money on before i heard the sweet sound of only 2 cylinders. Another couple weeks before i got to ride it on all 4. It's the same bike I'm sure you've finished by now. Good for us.
Well it would probably help if you had the throttle hooked up as well. And you should have a gas tank hooked up so you don’t have to worry about filling up the float bowls with gas
the reason it won't fire up on the gas in the carbs is because when you ripped them apart from each other you got them out of sync, no you need a carb synchroniser and you have to start the bike while its hooked up, check what needs to be changed, take them off of the bike, change it, then put them back on the bike and do the whole thing again until the carbs are tuned properly
One thing that can keep the fuel from being pulled from the float is a vacuum leak between the carbs and block. I had a few briggs engines that would fire on ether but not on gas. After I put some sealant on the seals after the carb they fired right up.
Sometimes if the gas tank isn’t on it won’t create a good enough vacuum to suck the gas in. Also if it’s backfiring that’s a fuel, spark, or stator issue
The gentleman that stated you DID NOT REMOVE JETS AND CLEAN was right.R&R carbs again a clean jets and passages, and it will probably run.As far as the oil in radiator ,the other gentleman was probably correct on the issue of a cracked head or bad gasket.You have a really GOOD channel,your learning ,keep us posted . Thank you!
I hope you read this. I was a motorcycle mechanic and I'll tell you exactly what's wrong. The oil seal in the coolant pump is bad and needs to be changed that's why oil is getting into the coolant. Common problem for old motorcycles. It's a cheap fix probably like $50. Also if you run a bottle with fuel and a fuel line going to the carbs and it'll fire up and run for as long as you want it to. They make cheap motor "IV" bottles you can buy if you don't want to make one. It sounds fine! It's gonna be fast in whatever you build. Plus those Honda F3 motors sound amazing! One of my favorite bikes!
For sure a blown head gasket, leaking oil cooler. Either that or some dummy filled the radiator with oil. I would also check the condition of the stator for your spark issue.
Andrew Meadors so I guess I’m some dipshit that doesn’t have a clue. There’s obviously some problem solving that needs to be diagnosed. I’m not there. If you had bothered to read my other comment. You may have already figured out that I had already realized that. I just didn’t assume. When you can see a very obvious problem you tend to go the basics. What I thought was funny was all the people saying don’t waste your time and money. Omg! That’s a cracked block and cracked head. I’ve replaced many head gaskets, but never a motorcycle. Especially a Honda.
Thomas Strickland obviously you're butthurt over your own idiocy because I never called anyone by name. Read my comment! It was a generalization and not finger pointing at anyone. Self guilt eats ones soul sometimes.
Echoing some of the other comments, without the negativity, I'd definitely replace the head gasket. Then get the entire air box assembled and feed the fuel from the actual fuel tank and see where you stand from there. The oil in the coolant is a very strong indicator the head gasket is blown or at least leaking.
I bought a 95 CBR f3, this time last year. It had been sitting under my boss' porch, in pieces, for 4 years. Tank was full of rust. Carbs were a mess. Over the past year, I have completely redone the whole bike. My suggestion, do your thing. Do your research and let the haters hate.
I have the same bike in my garage, a 1995 CBR 600 F3. It has 4,000 miles on it. I was hit by a truck that ran a red light in 1997. I broke my left knee cap in two and it ended up on the wrong side of my leg. The bike was repaired at the Honda dealer and sent back to my house. I haven't ridden the bike since then. It is still in my garage. I attempted to get it running again November 2017 after the last attempt of starting it and riding it to the end of the driveway and back in say 1999. But, that is as far as it had moved since then. I did get it running with constantly spraying starter fluid into the carbs. But then all of a sudden it started running horrible. One of the coils went bad and the ignition box the black square box right under the seat was bad. I ended up replacing both coils and the ignition box. I got it running good enough on 18 year old gas to take it to the gas station 2 miles away to refill it. It did start running better on new gas, enough to take it to the interstate. I started twisting the throttle wide open and all it would do is sputter. I could get the bike to say 90 mph in 5th gear but that was as fast as the bike would go. 6th gear would just bog out. But, the longer I did that the better it started to run. The final attempt to get it running better, I was at about 75 mph in 3rd gear with the throttle wide open. Black smoke was pouring out the back, then all of a sudden it smoothed out to about 9000 rpms then the front tire came off the ground all the way to 15,000 rpm. I remembered why I became scared of it. I backed off at about 145mph in 5th gear and it has plenty to go. I think the final carb opened up. It was unbelievably running smooth though. Something I noticed in the video when you got yours finally started. Yours isn't smooth at all. It should be as smooth as a clock work. To me it really could be a cracked head or a blown head gasket. But, I let mine set for a month and came back to it. And now it doesn't start at all. Well it does with constantly spraying starter fluid in it. The Honda dealer says that the carbs seats need to be replaced because of the alcohol now in the gas. So, if you want to get it to start and run well, you probably should look into that. I'm looking to replace my carbs rather than fix them. If you want any pictures of the parts of mine, just let me know.
Since it runs on starter fluid, something is wrong with fuel delivery. How far did you tear down the carbs? Has the jets, jet tubings been cleaned? Idle lines cleaned? :)
At the begining . The ice is from just running straight water. The oil in it could be bad rings or maybe bad seals if its oil but it could be block sealer
I had a bike do that to me. Wound up being the gasket against the motor from the carbs. It was shot. So when I could get it to start it would rev up high and die.
Dude I'm a huge fan man have inspired me to keep building thanks man I haven't missed a single video would like to get in touch with u some how and talk about a few of my projects but thanks man for making these videos most times I just watch your videos to fix something if idk how
How did you check for water in the oil? In my experience, you cant just look at it so I've started doing the sizzle test. You put a small amount on a noncombustible surface like aluminum foil and try to light it on fire; if it just smokes you're good, if it looks like some of it is boiling (i.e. bubbles) the head gasket shit the bed.
You're right, the air in the engine can condense. But in my experience, it will boil off with the heat produced from running the engine. However if the engine only ever goes on short trips and/or never sees the powerband it could be more problematic than not. My buddy had a truck that he rarely used and it would get some water drops on the oil fill cap when the humidity went back up in the summer. What I do is run the old oil to circulate it through all the galleries and if I think the engine is good for it I run it through the rpms to get some heat in there. After that, I'll change the oil and let that run for a bit and then test both oil samples. I do this at every oil change. I will say that it's a cheap and dirty test and I'm sure there are faster, better or more scientific methods but it has seemed to work for me so far and even saved my bacon once.
Make a 3 wheeled trike ....2 wheels in front one drive wheel in back ... The head gaskets are probably shot also and possibly cracked block...Do a compression test ....if good check cdi ignition module ... for spark issues ... ? I just hope that corrosive antifreeze didnt eat up those bearings and crank ...? Good luck 😀
I like watching your vids mate..... You struggle and learn from your mistakes, which is a good thing! BUT!....... I don't know if anyone has mentioned in the comments, Put the fuel tank back on the bike and connect ALL the pipework up to the fuel tap... You'll find a small VACUUM PIPE that connects to the tap, it usualy comes from the left inlet tract just infront of the carburretor rubber and it MUST be connected.......... OR.. if your going to use a small remote fuel tank just to get it running, the vacuum pipe has to be blocked off or else the motor draws too much air and won't start or when it does fire up it revs its tits off for a few seconds and dies... Most good service shops would use a remote fuel tank when the have the motor running with the fuel tank off in order to Ballance the carbs etc.... Trust me..... more than 36 years in the trade and ive learned an awfull lot as well as making many a mistake.!! haha!! Good luck mate.... Keep knocking the vids out.. Thanks...
Ho...... nearly forgot.... On most of the CBR600 ive worked on, they have an oil cooler between the Oil filter and the engine block.... They tend to rot from the inside out, especialy if the cooling system has never been looked after... (A lot of cars have the same system and suffer the same ailments!)..... That could be your "Oil in the water" issue... And one last thing..... If you strip the carbs down again, or at least take the float bowls off.. try and remove all the Jets (The little BRASS things you mentioned!) especialy the PILOT JETS and give them a blow through with an air line... Don't just rely on some magic potion carb cleaning solvent... The PILOT JETS control your engines idle... And i hope you removed the Digaphrams (the round(ish) rubber things under the round black caps on top of the carbs)... before dipping them in solvent.. and if you did.. I hope you made sure that they are seated perfectly because that will effect the starting and running...... and again, if you did remove them........ Arent those springs a nice job to get back in???!!! haha! Get a workshop manual........ It will help you greatly......
The green crapnin the carbs is residue from water corrosion on the brass bits in the carb. The most likely culprit is using ethanol fuel and improper storage. Should not be an issue in the future if you run good fuel. The next thing you should do is a compression check on all cylinders and if they check out, get the carbs tuned.
Best bet on that thing is to strip it down and hope you can get your money back on parts. There is nothing wrong with the oil because they changed the oil (with some cleanish used oil) before they tried to sell it hoping for a sucker. Old used car trick. That bike needs a complete tear down and rebuild. Get mad but that seems to be way over your head on a bike like this. You want a project like that get an older simpler bike. You are in over your head.
individually clean your injectors by hand using needles wire brushes ending at you can use to clean your injectors clean them by hand that might help it to fire better and able to stay running and keep it idle
You should look into getting an older 78-83 CB750a or CM450a with the hondamatic. It's a two speed auto with torque converter. Would be awesome rear mounted.
Put a proper ignition switch on it. Ebay usually has cheap new switches. Or figure out the wiring better. May need more than one jumper to get continuous spark. I had a ttr225 missing a switch and i needed to jump a wire for the power and another for run then could start off the start button. If I only jumped the power. I would only get spark for a second (enough to hear run) . Also bike may have switch on the kick stand or neutral that may keep from running.
Nice vid man, What i recommend/See: Do a compression test to start. Then do a leak-down test and obviously your gonna pull it of the chassis so tear it down in a video and get a good look at it good or bad. Then if you get leaks and or bad compression Tear down the head and have a wee look see. Its a 92? so the valves are probably tired. Check to see if the heads are a slight gold/yellow color near the pistons/valves and or chalky white color to indicate overheating. IMO thats alot of oil for a head-gasket leak. Maybe the dude was dumb and tried to make antifreeze with oil who knows. If its just a head-gasket then move forward with the carb restoration get a carb kit x4 and some carb cleaner and really go through each one especially all the jets it sounded to me like it was running real rich (more gas than air opposed to lean more air than gas). Try some new plugs NGK CR9EH-9. If then your spark still isn't so good might be time to check the gap on the coils if the gap is fine then may be the coils.... Process of elimination really with electrical problems like this. The thing is with CDI's are they work or the dont not kinda sorta. Check the stator voltage should be bout 25ac or so up to the regulator and the 11-14 out maybe 15 if your 5k+ but since it only runs for a second you wont get to 5k lol. Stators are funky they die over time ask the previous owner if he had a hard time keeping the battery charged thats a first sign. (basically its the alternator for small engines). CDI's are usually wicked pricey unless you can find a used one etc same with stators and regulators.
Your problem is those carbs when you cleaned them you didn't even take out the main jet or the pilot jet you have to take those out and blow compressed air through it or find something small enough to poke through the hole in the jet that's why it runs off starter fluid and not the gas in the float Bowl give it a shot I ran into the same problem. I know you think you cleaned them well but I guarantee if you do what I said that bike will run.
Horace Gray I didn’t show it in the video but I spent two days cleaning those carburetors making sure that all the jets and everything where cleaned out
rather B welding make yourself a remote starter switch with a momentary switch and some wire, that way you can crank it and run the throttle. Youre close, just keep working at it. 😁
I have seen alot of that green residue in the bottom of carbs, its from the gasoline from it sitting around and not getting ran. You need to blow out the jets with a air compressor and clean that residue out of the pilot jet, just soaking it will not completely clean it.
The ice in the coolant cracked the head that’s why it’s not starting, don’t keep turning it over you’ll fry the starter motor, do s compression test before you do anything
Ive got a 600 as my first bike and its great but its about personal preference and comfort. Also im not sure about where you live but here in Mass, you can get a title as long as you have a bill of sale from the previous owner and their old registration, or their bill of sale
ice in the coolant hose is a huge problem,more than likely something cracked because of the expansion of the water turning into ice. maybe your lucky and its just a gasket or seal on the water pump. as smart as you are,having a shop manual is the best tool you can buy. hopefully you didnt piss away 450 bucks.....
Can I buy the paper towels you used for the air filter? LOL! You should turn it into a three wheeler kind of like Can Am. Keep the Vids coming. Thanks.
I'm short and ride a CB500X - scary when you put your foot down and that part of the road is recessed. That 600 should be fine to ride for you. Adapt, overcome, dominate
And yes, beginning with a smaller bike is probably a good idea. Maybe even something between 100 and 250cc would be good to start with. You dont need to go 100mph at all times.
If you have a past with dirtbikes or something than a 600cc sport bike would be okay in most cases. You just have to know clutch and throttle control and these new fuel injected dirtbikes make you learn that stuff pretty quick cause they are twitchy
I really appreciate your videos I just got to building a Crossrails what I call it I'm from Alabama and built in memory of my daddy passed away a month ago it's got a CBR 600 and it it runs cranks but will not stay running sure would like some info
By the way the mini Trophy Truck idea is the best one. That thing will rip I have a 600cc Kawasaki zxr motor in my buggy and it runs great plenty of power.
The air-fuel mix is probably all fucked, it would run more consistently if it were set to what it is when its stock, then you could fine-tune it after it idles and all
no start and keep back-firing? have you checked the timing and valve clearance? also water instead of coolant, i woudnt even started it and started removing the whole engine to inspect the internal.
Mine has a fuel pump which pressurized the system may be the reason it's not running off the fuel in the bowl without the correct psi in the fuel system
Hey buddy do actually read any of these comments do you ever reply to them? before you waste time on the carbs you need to see if you have a cracked head or head gasket. I guess you're still learning. I would want to check the engine over since it looked like oil in the water!!! Just because it will start up and idle doesn't mean that it doesn't possibly have major problems. Before you spend more money on that engine get it running. The air box and air filter is not the issue why it wont stay running. I would run a compression test after it had the coolant freeze. Wow I saw you actually replied to a comment. Good deal you should read and COMMENT a little more to let the viewers know you are reading and trying there suggestions
nashguy207 yep the next thing to do on that bike is a compression test, then new spark plugs. And if the head gasket is bad that’s not as big of deal as everyone is saying it is.
Also the coils are a problem the connection is bad, sometimes when I turn the engine over for 5 seconds it doesn’t spark at all and I have to jiggle the wires around sometimes for it to work
I disagree with the 600cc engine being overkill for a quad. I custom built my quad with 2004 cbr600rr engine and yeah it's an animal but it's very controllable, comfortable, and there's throttle at all times. Any gear or rpm there is more. Do it you won't regret it
to much starting fluid will destroy the motor. starting fluid is either so it temporarily shrinks the piston rings to cause less compression so it can turn over quicker and easier rig a 2-liter bottle to feed the gas to the carbsand check for safty on the fuel feed to them
Don't throw parts at it sir. Are the coils even getting full voltage.. what about signal to them? Please knock out a compression test.. a little piece of mind and insurance. Great vids keep them coming..
Robert Dumesnil yeah they don't like cheap gas in engines smaller than a car, ethanol does a lot of hard to a small engine, thanks Joey From Statesville NC
Thanks, i´m a motorcycle mechanic and i like a lot your sense of persistence when you do things you don´t know.
Congratulation for the genius work you develop in your man cave!

Leaky oil cooler.
how about he spends the money on service manual. I have never seen him open one up. Part of a learning experience is ACTUALLY LISTENING to other people and allowing them to help.!!!!!!!!!!
Your such a jerk. Can you try to be polite for once? I wouldn't listen to you either if I was him.
I wonder if the ice in the coolant system cracked the block? You may want to run a compression test before doing anything else.
I brought one (1994) back to life about 8 years ago so I understand the feeling. I didn't have to remove the engine from the frame, though.
I would start with a compression test on all cylinders, there is no point in spending time and money on any parts until you know the condition of the engine.
Specialy after finding oil in the water! Thinking head gasket.
What should the compretion be?
I did a full restomod project on an 87 cbr600f1 hurricane. It was a cool bike to work on and it was one that i spent weeks working on and spending money on before i heard the sweet sound of only 2 cylinders.

Who's here in 2018? Great vid so far, Chris! Keep it up!
John C anyone is gonna be here 2018 he just uploaded it
is his name chris?
Jk, lol. 😂
Yes, it is.
Love the videos diagnosing problems on these types of things
That green stuff is from the ethanol that they have in this new cheap gas these days, thanks for all the content, Joey From Statesville NC
Sometimes if the gas tank isn’t on it won’t create a good enough vacuum to suck the gas in. Also if it’s backfiring that’s a fuel, spark, or stator issue
The gentleman that stated you DID NOT REMOVE JETS AND CLEAN was right.R&R carbs again a clean jets and passages, and it will probably run.As far as the oil in radiator ,the other gentleman was probably correct on the issue of a cracked head or bad gasket.You have a really GOOD channel,your learning ,keep us posted .

crank driven waterpumps are a known interchange spot between coolant and oil.
For sure a blown head gasket, leaking oil cooler. Either that or some dummy filled the radiator with oil. I would also check the condition of the stator for your spark issue.
It's not. The oil coolers on these bikes are enclosed in a coolant passage. Most likely just a leaky oil cooler.
Kyle B I thought about that afterward. Then I thought it might not even have an oil cooler.
Kyle B thank you. These TH-cam mechanics on here crack me up.

P.s. be sure your vacuum lines are all hooked up. Especially the one to the vacuum solenoid valve.
been subbed for quite some time but just realized you look like the chef fro ratatouille
A mini trophy truck would be unreal and a lot of people would love to see that build.
I have the same bike in my garage, a 1995 CBR 600 F3. It has 4,000 miles on it. I was hit by a truck that ran a red light in 1997.

The tank being above the carbs creates a little fuel pressure and check all the plugs

New plugs , and a gas tank to keep the gravity fule pressure to the carbs.
Great video, the idea of a trophy truck is great.

I will say that it's a cheap and dirty test and I'm sure there are faster, better or more scientific methods but it has seemed to work for me so far and even saved my bacon once.
Make a 3 wheeled trike ....2 wheels in front one drive wheel in back ... The head gaskets are probably shot also and possibly cracked block...Do a compression test ....if good check cdi ignition module ... for spark issues ... ? I just hope that corrosive antifreeze didnt eat up those bearings and crank ...? Good luck 😀

I like watching your vids mate..... You struggle and learn from your mistakes, which is a good thing!
BUT!.......
I don't know if anyone has mentioned in the comments, Put the fuel tank back on the bike and connect ALL the pipework up to the fuel tap... You'll find a small VACUUM PIPE that connects to the tap, it usualy comes from the left inlet tract just infront of the carburretor rubber and it MUST be connected.......... OR.. if your going to use a small remote fuel tank just to get it running, the vacuum pipe has to be blocked off or else the motor draws too much air and won't start or when it does fire up it revs its tits off for a few seconds and dies... Most good service shops would use a remote fuel tank when the have the motor running with the fuel tank off in order to Ballance the carbs etc....
Trust me..... more than 36 years in the trade and ive learned an awfull lot as well as making many a mistake.!! haha!!
Good luck mate.... Keep knocking the vids out..
Thanks...
Ho...... nearly forgot....
On most of the CBR600 ive worked on, they have an oil cooler between the Oil filter and the engine block.... They tend to rot from the inside out, especialy if the cooling system has never been looked after... (A lot of cars have the same system and suffer the same ailments!)..... That could be your "Oil in the water" issue...
And one last thing.....
If you strip the carbs down again, or at least take the float bowls off.. try and remove all the Jets (The little BRASS things you mentioned!) especialy the PILOT JETS and give them a blow through with an air line... Don't just rely on some magic potion carb cleaning solvent... The PILOT JETS control your engines idle...
And i hope you removed the Digaphrams (the round(ish) rubber things under the round black caps on top of the carbs)... before dipping them in solvent.. and if you did.. I hope you made sure that they are seated perfectly because that will effect the starting and running...... and again, if you did remove them........
Arent those springs a nice job to get back in???!!! haha!
Get a workshop manual........ It will help you greatly......
The green crapnin the carbs is residue from water corrosion on the brass bits in the carb. The most likely culprit is using ethanol fuel and improper storage. Should not be an issue in the future if you run good fuel.
The next thing you should do is a compression check on all cylinders and if they check out, get the carbs tuned.
The trophy truck idea sounds good! Hope you go with that.
If there’s ic in the tube you might want to check for cracks in the block
Kazoo Bros if there is ice in the tube that means the guy put water in the radiator
Timo Hacks. Ya but water is also in the block and ice expands it can crack the block
Joey T oh my bad
Best bet on that thing is to strip it down and hope you can get your money back on parts. There is nothing wrong with the oil because they changed the oil (with some cleanish used oil) before they tried to sell it hoping for a sucker. Old used car trick.
That bike needs a complete tear down and rebuild. Get mad but that seems to be way over your head on a bike like this. You want a project like that get an older simpler bike. You are in over your head.
individually clean your injectors by hand using needles wire brushes ending at you can use to clean your injectors clean them by hand that might help it to fire better and able to stay running and keep it idle
You should look into getting an older 78-83 CB750a or CM450a with the hondamatic. It's a two speed auto with torque converter. Would be awesome rear mounted.
The green residue in the carbs can be indicative of bad gas containing ethanol.
Put a proper ignition switch on it. Ebay usually has cheap new switches. Or figure out the wiring better. May need more than one jumper to get continuous spark. I had a ttr225 missing a switch and i needed to jump a wire for the power and another for run then could start off the start button. If I only jumped the power. I would only get spark for a second (enough to hear run) . Also bike may have switch on the kick stand or neutral that may keep from running.
Nice vid man, What i recommend/See: Do a compression test to start. Then do a leak-down test and obviously your gonna pull it of the chassis so tear it down in a video and get a good look at it good or bad. Then if you get leaks and or bad compression Tear down the head and have a wee look see. Its a 92? so the valves are probably tired. Check to see if the heads are a slight gold/yellow color near the pistons/valves and or chalky white color to indicate overheating. IMO thats alot of oil for a head-gasket leak. Maybe the dude was dumb and tried to make antifreeze with oil who knows.
If its just a head-gasket then move forward with the carb restoration get a carb kit x4 and some carb cleaner and really go through each one especially all the jets it sounded to me like it was running real rich (more gas than air opposed to lean more air than gas).
Try some new plugs NGK CR9EH-9. If then your spark still isn't so good might be time to check the gap on the coils if the gap is fine then may be the coils.... Process of elimination really with electrical problems like this. The thing is with CDI's are they work or the dont not kinda sorta. Check the stator voltage should be bout 25ac or so up to the regulator and the 11-14 out maybe 15 if your 5k+ but since it only runs for a second you wont get to 5k lol. Stators are funky they die over time ask the previous owner if he had a hard time keeping the battery charged thats a first sign. (basically its the alternator for small engines). CDI's are usually wicked pricey unless you can find a used one etc same with stators and regulators.
Your problem is those carbs when you cleaned them you didn't even take out the main jet or the pilot jet you have to take those out and blow compressed air through it or find something small enough to poke through the hole in the jet that's why it runs off starter fluid and not the gas in the float Bowl give it a shot I ran into the same problem. I know you think you cleaned them well but I guarantee if you do what I said that bike will run.
Horace Gray I didn’t show it in the video but I spent two days cleaning those carburetors making sure that all the jets and everything where cleaned out
rather B welding try opening the throttle a little while cranking, it should go
rather B welding make yourself a remote starter switch with a momentary switch and some wire, that way you can crank it and run the throttle. Youre close, just keep working at it. 😁
I have seen alot of that green residue in the bottom of carbs, its from the gasoline from it sitting around and not getting ran. You need to blow out the jets with a air compressor and clean that residue out of the pilot jet, just soaking it will not completely clean it.
The ice in the coolant cracked the head that’s why it’s not starting, don’t keep turning it over you’ll fry the starter motor, do s compression test before you do anything
Ive got a 600 as my first bike and its great but its about personal preference and comfort. Also im not sure about where you live but here in Mass, you can get a title as long as you have a bill of sale from the previous owner and their old registration, or their bill of sale
Next time you reuse oil filter it with a cloth or coffee filter. That way you can actually see if there was any shavings in it.
The sparkplug will not spark every time, because it does not fire all cylinders at the same time
ice in the coolant hose is a huge problem,more than likely something cracked because of the expansion of the water turning into ice. maybe your lucky and its just a gasket or seal on the water pump. as smart as you are,having a shop manual is the best tool you can buy. hopefully you didnt piss away 450 bucks.....
Can I buy the paper towels you used for the air filter? LOL! You should turn it into a three wheeler kind of like Can Am. Keep the Vids coming. Thanks.
wayne brown can am spyder
I'm short and ride a CB500X - scary when you put your foot down and that part of the road is recessed. That 600 should be fine to ride for you. Adapt, overcome, dominate
Green tint could be due to engine oil getting into carbs getting past the oil rings but that could of been build up for 10 years
It's the electrical the motorcycle has occasional pops when the compression and spark happen at the same time
I had the same problem the fule rale needs to have presser or more fule pushing it in to the engine
Will Hatch
Yep this is what I thought too
Mini formula one build would be really cool. You def need a throttle cable to feather the gas some, Honda’s are not great at idling cold.
My honda trx 450r backfired slot when valves needed adjusting, and when my jetting was way off. Just a few things to check out
You're mad taking all 4 carbs apart, they'll be a nightmare to balance after reassembly.
check the valve clearances and replace the spark plugs
I would keep it running for a bit then leave the coolant in there and check the coolant again in a couple weeks and see if there is oil in them again
You probably need a constant fuel suply. I know my Yamaha xj750 needs perfectly full float bowls to run as it should.
And yes, beginning with a smaller bike is probably a good idea. Maybe even something between 100 and 250cc would be good to start with. You dont need to go 100mph at all times.
I bet its the rectifier since its sat for so long
Also to keep it running i bet it needs a fuel pump to be able to keep up pressure in the carbs
You do know cbrs have a zener diode for the ignition around the 2000 year models so if you try to bypass the ignition the fuel pump wont run
Get the badlands ST4 buggy plans mate. I’m building one at the moment and I’ve put a Zx9r engine in it 👍🏻
Can you do a basic wiring diagram for these cbr engines i have a cbr750 im putting on a 4 wheeler and need the wiring
Get new plugs And hook up the throttle and open the throttle with choke on. Being that the bike has sat for so long it's not going to idle right away.
If you have a past with dirtbikes or something than a 600cc sport bike would be okay in most cases. You just have to know clutch and throttle control and these new fuel injected dirtbikes make you learn that stuff pretty quick cause they are twitchy
I really appreciate your videos I just got to building a Crossrails what I call it I'm from Alabama and built in memory of my daddy passed away a month ago it's got a CBR 600 and it it runs cranks but will not stay running sure would like some info
it should have an electric fuel pump and as for the hard to start thing that's just from it sitting for a long time
By the way the mini Trophy Truck idea is the best one. That thing will rip I have a 600cc Kawasaki zxr motor in my buggy and it runs great plenty of power.
The air-fuel mix is probably all fucked, it would run more consistently if it were set to what it is when its stock, then you could fine-tune it after it idles and all
It’s a bad head gasket because oil was in the radiator. It’s got bad compression
That green tint was probably caused by ethanol in the gas
I came across one of these bikes was abandoned in a military home....since 2005 are they worth for parts??
no start and keep back-firing? have you checked the timing and valve clearance?
also water instead of coolant, i woudnt even started it and started removing the whole engine to inspect the internal.
Mine has a fuel pump which pressurized the system may be the reason it's not running off the fuel in the bowl without the correct psi in the fuel system
Connect a fuel tank or can to it and it will run. It is not timing, it is computer shorting out. Inconstancy is always computer. or bad relays.
Hey buddy do actually read any of these comments do you ever reply to them? before you waste time on the carbs you need to see if you have a cracked head or head gasket. I guess you're still learning. I would want to check the engine over since it looked like oil in the water!!! Just because it will start up and idle doesn't mean that it doesn't possibly have major problems. Before you spend more money on that engine get it running. The air box and air filter is not the issue why it wont stay running. I would run a compression test after it had the coolant freeze. Wow I saw you actually replied to a comment. Good deal you should read and COMMENT a little more to let the viewers know you are reading and trying there suggestions
nashguy207 yep the next thing to do on that bike is a compression test, then new spark plugs. And if the head gasket is bad that’s not as big of deal as everyone is saying it is.
Also the coils are a problem the connection is bad, sometimes when I turn the engine over for 5 seconds it doesn’t spark at all and I have to jiggle the wires around sometimes for it to work
I agree if its just head gasket it can be replaced but if head is cracked thats a different story.
agreed, ice can do major damage
I disagree with the 600cc engine being overkill for a quad. I custom built my quad with 2004 cbr600rr engine and yeah it's an animal but it's very controllable, comfortable, and there's throttle at all times. Any gear or rpm there is more. Do it you won't regret it
compression test always first bro. The ice up situation is a very bad thing, could lead to cracked head and casing.
If the plugs are wet, don't use the choke.
I really think the other engine was just a timing issue.. The exhaust valves were just popping too soon
Time for new cdi box
Do a compression test on all cylinders you have the tool now...
You bought a bike with a high probability of being stolen and you bought a water cooled vehicle without checking the coolant.
You have to charge the spark plugs. The Cbrs are REALY sensitiv, to bad spark plugs.
Trophy truck for sure that would be sweet man
to much starting fluid will destroy the motor. starting fluid is either so it temporarily shrinks the piston rings to cause less compression so it can turn over quicker and easier rig a 2-liter bottle to feed the gas to the carbsand check for safty on the fuel feed to them
Why don’t you hook up the gas tank to the carbs? The engine is firing.
Like to me I would start with the most simple things for the spark and that would be a set of plugs
Get some 8mm plug wires, then get some E3's for it and maybe check cap and rotor.
this is what the dutch do with CBR600 engines: th-cam.com/video/hPtJGWdwBoc/w-d-xo.html
Don't throw parts at it sir. Are the coils even getting full voltage.. what about signal to them? Please knock out a compression test.. a little piece of mind and insurance. Great vids keep them coming..
I know the motorcycles that I owned I used highest octane fuel. Just a heads up.
Robert Dumesnil yeah they don't like cheap gas in engines smaller than a car, ethanol does a lot of hard to a small engine, thanks Joey From Statesville NC
First get it running, drive it around for a little bit as a motorcycle then pull the motor and use it for a buggy
Christian yeah!!!!🤔🤔🤔🤔🤔
Hey bro any shot you’d be able to help me out getting my 05 to fire up? Lol I think your input could help
Minature trophy truck sounds awesome
I think I would start with just replaceing the plugs before I replace the coils.
Check the ignition you have a on and a start
Just like in a car
I need help with the vaccum system how did you hook the vaccum up
