- These two parts are priceless in my opinion. I couldn't be happier with the overall performance, reliability and peace of mind that together they provide. I would never build a bike without these two must have upgrades.
Watch at 1.25 playback speed
I did right away sooooooo much better good info i wanted
Sounds upbeat now. Thnx.
I tried 0.5x i died laughing😅
thanks much better
@@speedy-cc .5 speed sounds like bike mechanic plus a pint of bourbon. Indeed hilarious.
Makes me extremely nervous too. Good call on that
I have been on this kick lately about chain tensioners..and you have it right..this is the way I have mine set up..spring loaded off the clutch cover, (away from rear wheel) plus changing out the plastic guide wheel with a metal sprocket..way to go..great setup and build
I will agree 100% I have both on my bike plus a # 41 chain never a problem when installed right guaranteed. Been on mine from day one lots of off road rideing never thrown a chain. Bike peddels almost as easy as without motor. Makes your bike solid youll truly enjoy.
Great advise! I also replaced my wimpy back rim with a weinmann d30 heavy duty rim! $75. Much stronger wheel. Heavy duty spokes! Happy trails all!
A huge world of difference, takes all the vibration from the assignment an smooths everything out
Man I agree 100% about Rag joints, chain tensioners. If a bikes worth building Its worth the extra $$s to do it right. Huge thumbs up. 👍
sprocket hub assembly and chain thingy spring built onto motor! i paused at 17 seconds and guessed what two parts are!
I have just bought one of these engines i have ordered all the up grades as I didn't like the chain tensioner air filter or rear sprocket set up well Done good explanation
Hey man, I used to build these things for sale and I completely agree with you 100%. In addition I also would get completely aluminum throttle with rubber grip since the stock ones have broken for me many times.
Had them break on me to. So for my next build I plan on getting a high quality motorcycle throttle. Would be a huge step up fromt the kit stuff.
spacemonkey yeah jnmotorbikes I believe is the business name sells all aluminum throttles I got on one of my bikes, works amazing and very durable.
That hub adapter mount sprocket kit and spring tension mount is awesome 👍😎👍
Check out my videos dude I have the same parts
What is the best chain tensioner there is for a 4 stroke that's similar to this one in the video?
Thank you, great video, I am off to get the sprocket adapter and chain tensioner ... 👍🏻👍🏻🙏🏻
I got a spring idler chain tensioner that mounts on the chain stay like the original one. Do you think it would be better to get the one that mounts to the clutch cover like yours?
I liked your video on the sprocket .I have one on it's way soon but I'm going 56 tooth sproket.Hoping I don't have to replace my Heavy duty Chain. Thinking of the chain tensiner. Great video thank you. 👍🚴♂️
Wow that idler pulley is the Original junk Idler, that has very high chance of snapping a chain. I have the newer idler but it's still snapping chains, I'm going to upgrade to the HT Spring Idler like yours that chain looks flawless.
been think of buying this bike and riding it as a pedal bike. is the bike alone any good? i am 6'2" and 210 lbs. think it is too small for me? any thoughts would be appreciated. i can not find any reviews on this bike that is why i am asking you. thanks in advance.
Nice video... I did end up ruining a back wheel when the chain tension-er ended up in my spokes on my first build.
could you possibly send me the link where i can purchurse those two parts?
Spring tensioner would be the ideal solution, but I used the stock one. I put a rivet in it to keep it from falling into the spokes. I did the same with the coil and tank to keep them still. Very cheap upgrades!
aomimezura11 how and where do I put a rivvet in my tennsioner?? Please
DA ONLY THING DAT CAN IMPROVISE IS ONVENT OR COME UP WITH IS TO ADAPT OR FASTEN SOME HEAVIER GAUGE TYPE OFBMETAL OR STEEL TO DAT METAL BRACKET WOULD BE A MUCH LONGER TO BOLT ON TO SEAT AND CHAIN STAYS BY WAY OF A METAL CLAMP TYPE DA PNES DAT ARE USED ON COASTER TYPE BRAKE BRACKETS PROBLEM FIXED I IMPROVISE THANKS TO YOUR ASKING OR EXPLAIN. I LIKE SHARING INFO WE CAN IN CORPERATE AND HELP EACH other. This wat i like to do. I later in life watch alot A TV SHOW CALLED Mc, GAVER. IDEAS.
@@RafaelSantos-vd6be the f you on son
26mph isn't bad at all.. What engine kit is that? Very nice. How much are you in on everything with the Bike, engine kit + all your upgrades? ?
Completely agree with you...the stock tensioners are horrendous. Not to mention if you have a slanted rear frame, it is very hard to install and can easily derail the chain. The stock tensioners also seem to over-guide the chain and derail it. The spring tensioners are really great. It doesn't put wear on the chain, it's much quieter, and dramatically improves acceleration and top speed.
first thanks for the video I do agree with you in both of this items. I have a question as for the carburetor, I noticed that you are using the stock exhaust, did you re-jet the high performance carburetor and if so what size jet are you running? I ask you because I tried one of them with my 80cc and with the stock exhaust it would choke, after putting and expansion chamber it still does, not as bad but I choose to take it off, because it was still choking. Something else that the sprockets guys make is the rubber motor mount, these are nice also.
sorry for the late reply man. I did rejet to a .64mm. It's a little cold blooded with this lean of a jet but once it warms up it runs great. These carbs are limited in tuning to either jetting or the idle adjustment screw. Chances are you will not have perfect throttle response from idle to wide open throttle but a .64 jet was the best overall for me.
I have 2 KHS 150 elite bikes and thay both have the 2.75 horse power motors on them one has almost 4000 miles and pull a bob trailer the other not quite 300 miles and all stock parts I agree with you on chain tensioner and sprocket and yes I will do up grades Soom thank u be safe out there
Agreed. I have rear mag wheel sprocket is must
Spring tension yes must have
I want to get that chain tensioner setup this is the best setup yet you said you can only get it off Ebay?
The chain tensioner was my nightmare too..! I saw this piece of shit tilting towards the wheel while I was doing 40 mph. So, I made a similar solution myself. Yours is made out of aluminum mine is stainless steel but only 2 mm thick plate and the arm has a little bend lengthwise in order to be light but incredibly sturdy. I might invest in the sprocket because I haven't the tools to CNC machine it.
Happy riding..!
Very good idea getting a different tensioner. I have had mine rip several spokes out but I can't afford to get a different one.
They can be ten bucks on amazon
I just installed the chain one and I can say the stock one with zip ties holding it up was way better
will it fit my mountain bike??, how long was the wait for gas bike? I heard they got a bad wrap for delaying orders for weeks, thanks.
I got my bike kit 2 days after order with normal shipping
how fast does your go? mine does 40mph with the same sprocket.
I bought my bike already built and ready to go from a guy. I road the bike before I bought it and everything, everything was fine until I got home and tried the bike again. The tensioner that they give in the kit is horrible! I had 4 spokes ripped out of the rim!had to get a whole new wheel, then broke 3 spokes out of that one. You are way better getting a tensioner like that. I will be getting these parts as I get paid. Loving your videos, I am learning a lot, thank you man.
Sounds about right thanks.
Do you know if you could use this sprocket adapter to drive an electric motor on an ebike what type of sprocket is on the gas motor you run
Where can you get that chain tensioner in Australia? Apparently the adapter for the back sprocket can slip and it is a good idea to put a keyway in.
On that rear wheel sprocket is it better to have more teeth or less teeth on the sprocket I seen some 36- 44 -& 48 teeth
I never had any problems with stock chain tensioner but my brother ruined 3 wheels with his. (Feel in on the wheel) So we both bought the same one u have, and its awesome
Fell*
I have that problem on my bike with the stock chain tensioner
Lol I did have the problem with the tensioner going towards my wheel but after I tightened it up more it went better but I'm also still using rag joints but I just ordered the adapter and new tensioner can't wait for them to come thru
Is that adapter better than the 6 hole hub adapter?
thanks for the info
I have the hub adapter, but I've been putting off the tensioner. I can't believe I never thought about the stock tensioner being pulled into the spokes. As long as it's tight, you're good, but I'd rather eliminate that possibility altogether.
Very good idea not only eliminates that issue and makes the bike a lot smoother all around
Always change out the bracket bolts for grade 8 hardware! the stuff that comes with the kits will strip before they can really hold that bracket tight enough not to move. Then, buy the black spring loaded chain tensioner from eBay - Works great and comes from Montana.
sprocket adapter and spring chain tensioner FTW!
I have a similar gas bike style rear adapter. interestingly, it actually works put on either way because the recessed side allows it to sit further onto the inner Hub so the space and comes out almost identical either way you put it - although I still prefer the way shown in the video where the bolts are flush, so even if things start to come loose you've got less chance of the bolt shearing off against the freaking coaster arm or something like that.
rear sprocket adapter is one of the only parts I assemble with Red (permanent AF!) Locktite so it lasts at least a couple thousand miles. Blue Locktite it the first time though, and it'll last you couple hundred miles unless you tighten it too hard or too weak
next upgrades on my prefs list could maybe be expansion chamber and Sturmey-Archer front drum brake or disc brake
when you say you use red Loctite, do you mean between adapter and hub to prevent slipping? or on the adapter/sprocket bolts to prevent loosening?
With those horizontal dropouts, you wouldn't have needed a chain tensioner at all. You could remove the right number of links, and slide the rear wheel back until you get your proper chain tension.
Instablaster
I put this chain tensioner on and it makes the chain bounce just a little. so on start up the motor throws the chain forward for a split second and with those two motions combined at just the right time it locks the chain up in that curve in the sprocket housing and it flipped me of my bike
True talk a agree must have for sure 👍
How do you get the spacing from the chain like that because with mine the chain is really close and hit each other
If you mean, your chain is rubbing on th same chain. Take a link out of it.
i think even better than the pinch mount adapter is to use a disc brake wheel, mounting the sprocket most securely in place of the disc rotor
could you send me a link for the tensioner
Love all your opinions except the standard tensioner works great if you bolt it into the frame and the further back its mounted the less binding. I've tried both ways I still recommend a spring one but I have a problems with chains jumping on the springs
On my motorized bike on the top chain after about around 2 inch of slack or more top drive chain in middle. I try to periodically check this measurement before riding. I knew I should have tightened it before I took it out but you know how that sometimes goes when you want to go riding. the chain jumped off the first time then the second time from chain too loose come off and binded up I replaced it. But I find if the drive chain I'm speaking of is too snug it's very hard to pedal. The looser chain gets the faster you can pedal it. And I'm sure this goes for the pedal chain too. And I have the stock flat wheel chain tensioner non spring loaded. About how much slack did you have in the top chain when it jumped off if you noticed?
How tight does the arm with the spring should it be?
I'm still using the original chain tensioner and yes, if you aren't careful that thing can easily slip and lock your rear tire up. One thing I did to prevent it was take an old bike inner tube and cut a couple pieces to wrap around the tube on the bike then installed the tensioner over the inner tube and cranked the bolts down, it hasn't moved at all since doing that.
I'm thinking about updating my rear sprocket to the adapter type setup you have, it looks far superior to the rag joint setup. I'm using the rag joint setup right now, but the sprocket & adapter is definitely on my upgrade list. As for the rest of the engine I don't really plan on doing anything else to it for power, it does 30mph on flat ground, that's plenty fast for bicycle tires LOL.
BTW, great detailed video and explanations of why these items need to be addressed, the tensioner is a major safety issue, if that thing slips into the spokes of your back wheel, it can throw you off the bike in a heartbeat.
I didn't know about gasbike.net until running across your video, I got my kit from Bikeberry, but looks like gasbike.net has far more accessories and options.
Careful with gasbike though man. They have HORRIBLE customer service. I don't really deal with em anymore.
I never did self-taught we know more about them than the people who sell them
Rimshot Recluse They're all chinese engines, none of the places that sell this stuff have any sort of customer service skills :(. I bought an analog speedometer kit it broke after the first ride of less than a mile, was far from impressed, bikeberry wanted me to pay to ship it back to them, I said hell no threw it in the trash and ordered a digital one from ebay which has worked great.
Reminds me I need to get more fuel LOL, ran 87 miles on a gallon. Seems to run great other than the couple issues I've had one broken mounting stud, and the speedometer.
This is at least the third hack I've seen/read about for using old innertube ;) One was to use it between the engine mounts/brackets and the frame to reduce shaking, and the other was to cut circular "grommet" type pieces to seal the [cheapo kit] gas can cap to the can so as to prevent leaks while riding.
This comment seems an awful lot like a gasbike.net advertisement
Hey should I get a mechanical break for the my bike or will the standard breaks that come with the kit be enough?
The brakes on the bike already are fine.
Did you try to get a new exhaust?
Looks like you got that chain lined up straight- that's so important! In my opinion, those xxhain tensioners are waaay over priced for the materials they're made from its ridiculous. People reallyneed to be wary of parts for these on the internet; make sure to shop around for Everything you're looking for cuz there are a wide range of qualities and costs and the kicker is that those two do not always match up!
I did the same thing. Did my research and people said the rag joint and spring tensioner is crap so I never even used them. My adapter slipped (used some different materials as a shim and failed) and messed up my spokes. Problem is that I bought a one inch hub adapter and my hub is just barely smaller than that. Thus right now I am grounded and considering mag wheels or fixing the current rim and really working hard to engineer some shims so it doesn't slip again.
Bike Berry did a video on what you need to do to the hub mounts to make them work. Have to shave a bit off one end of one half so it clamps tighter and make a keyway in the hub & hub Mount. I'm sticking with rag joints as I don't have the tools to machine all that. I have one of those chain tensioners tho, they are phenomenal
Nice!
Is that a Cranbrook? I have a red one but it doesn't have a back rack like yours I wish I had a rack for carrying stuff like tools and food
Dear Sir-Still on the fence with the sprocket adapters. My 13 year old first bike build was stolen last Friday:( Have you had any problems with your sprocket adapter slipping?My new bike has a painted hub, which I don't know if this will be an issue with the hub adapter slipping. The incoming sprocket adapter does have recessed screw holes. Thanx for any updates-John in Texas
You can always drill threw the chain tensioner and chain stay to keep it from moving. I prefer the tensioner shown in this video.
If your having problems with top speed I would definitely invest in an aftermarket exhaust
right on , built a mongoose fat tire, this is a must, for the build, even I'F I built a regular run of mill bike I'D still install, them coggs made of rubber is a death sentence
Thank you.
Where can I get a speedometer like you got on you're bike. Got digital on my bike but prefer old style, cheerstafanx Rab
I got mine from Amazon. Its a sunlite brand analog speedometer. you can get it cheaper if you buy it from one of the other sellers not amazon themselves. I think i paid 13 dollars free shipping.
Bet an upgrade exhaust would get you a couple more miles per hour.
I've always had best luck never needing a chain tensioner..but if you must..that one looks good.
I use both tensioners
Is that a Huffy bike? What size diameter is the rear hub for the sprocket adapter? Thanks!
svrblk777 most all single speed coaster brake hubs are 1.5". thanks
Do you think you could run rear suspension with that chain tensioner?
Ya know, I really don't know man lol.
Brilliant and efficient. Very organized with all your equipments and parts. Thanks
Well is there any links to where to buy these?
Talk about "not safe" how about that coaster brake?
What kind of bicycle is that? Do you still have this bike running?
Where you get the speedometer?? Only found kph
Would love to know where you found a Speedo in MPH not KPH.
To get more speed you need to upgrade more smaller sprocket tooth count gets more speed but also to get better performance from your engine get a boost bottle and the intake for the boost bottle line to connect too and replace the stock exhaust with an expansion chamber exhaust also a higher performance cylinder head instead of the stock one it came with for better compression and better flow
Will that spring tension fit on my BBR tuning 4 stroke motor
No
Where can I buy those reset bolts?
Can you make a video on putting it on
TY
Is that a Nel lusso?
Ya know I've seen a lot of videos about Chain Tensioner Idler being a danger and should be changed, but I have never saw a case of it happening and if it's such a big risk why are they still being sold?
What hub size it that sproket adapter they come in three sizes I got the wrong one
matthew naylor most all single speed coaster brake hubs are 1.5" thanks
I got that tensioner because I was riding it with the old tensioner and it folded into the spokes and destroyed my wheel
I baught the same chain tensioner for my motorized bicycle and I love it. The only thing I don't like about it, it's the roller that come it. The chain comes of when you ride and sometimes you have to put the chain back on which is so annoying and worthless. Please change the roller and put on the other roller that comes with the stock tensioner, that way you have problems with your chain coming off. I hope it helps for someone who have the same issues that I have
I meant you won't have problems with your chain coming off with changing the roller to a stock tensioner roller.
I'm going to use the original chain-tensioner that came from the kit from China, but use taut -twisted copper-wire to ensure placement, and polish the wire before clear-coating it. Yeah, all my bikes are "art-bikes." The new Krylon 'color-shift' paint is da bomb if you have a bag of graffiti tips lyin' 'round yer flat.
I got the same tensioner but with a gear Roller not the plastic junk. It still falls of but due to my tire being too fat and the sprocket being unaligned. I'm going to fix that tonight, but other than that I love the difference its semi easier to install too
U just have to make tensioner really tight and that should stop it from going into spokes that what I did no more problems so far but I did order spring tensioner off ebay.
That tensioner is 100% necessary. I use the rag joint though lol
I would really like to get that spring tensioner where can I purchase that if you could give me the info I would greatly appreciate it
hey dude sorry for the late reply. you can find it on ebay. It's like 35 bucks or so. Thanks
Wats the size please for beach cruiser
my Huffy Grand Canyon mountain bike has a 5/8 hub. This is a very common bike. Not sure what to do.
The Seeker-UrbEx Where did you buy your sprocket adapter?. I to have a small hub and need this adapter. Thanks
Please list in the comments, the websites where you obtain items.
hey i have the same spring tensioner but every time i try to start it the chain become un-tensioned and gets jammed on the top, any suggestions?
Yes same thing used stock with screw in it at one time I was moving the back of tire back in it slots
Tbh I find that even without this chain tensioner that happens. The way I found to combat that is take the manifold off there and the back plate of it that the chain would ride on I ground it out in a half moon shape just enough room for the chain to more freely turn under the manifold. It's a problem with all of these kits even the "bbr tuning" over priced JUNK
Ps yes bbr tuning all your products suck and literally chinese kids in sweat shops make better products than bbr tuning
can you make a video for sprocket gear to change speed.
AT1234 you either need a transmission or you need a smaller sprocket to go faster. Or a larger on for more torque
cool bike really like the color") this is a very good video the information here is priceless and very well presented! thanks rimshot for posting a great video. You want more speed change to a 36 tooth rear sprocket
+brian noel Hey brian! Thanks man. I recently got my bike running so much better. I jetted the carb and wow what a difference. After a lot of trial and error I finally settled on a .64 jet and it runs sweet now. I actually made a video about it. Check it out dude.
+brian noel Im going with a 32 tooth sprocket :)
Rimshot Recluse awesome stuff rimshot yes I think that carb you got is way better that the stock NT but wondering does it deliver the same in MPG performance?
Mindtone 32 is pretty high gear for street riding and gonna require lots of pedaling to get goi ng but it will make you fast at the top end post a video so we can see your bike
ok sounds good
Well a bit over a year into the engine and I've managed to break 2 engine mounting studs so far. I haven't replaced the latest broken stud as for some reason I have managed to lose my broken bolt extractor kit LOL.
Once I get that stud removed and new ones installed I'm installing a vibration dampener kit. Then I plan on getting that new idler pulley setup you are using as well as replacing that rag joint setup.
Other than the engine mounting studs I haven't had any issues out of my engine. Its a pain to start after it sits for months on end, but once you get it going it runs great...tops out at 25mph and I've only got about 160 miles on it.
I found a sprocket addapter for 36 bucks with 36T sprocket not sure how it will work guess ill find out
Chirs Burkett Nice!. Where did you buy your sprocket adapter?. Thanks
The other rear sprockets not dangerous it's just a pain in the ass to install I know from experience I wish I had the sprocket you had right now it looks so much easier to install and it looks way better
Thats a lie if your using a old bike its dangerous like poeple dont have money to buy a 98 dollar huffy cranbrook lol
My tensioner came in right at a turn after a 40mph stop and broke my spokes and masterlink, i ordered this tensioner with the sprocket instead of the wheel
How you made that aluminium rear wheel sprocket adapter ,al moulding, or through online,
Victor Konsam online
@@chrisl8680 ,for me ,,,,,,,,,,, ,,,,,,, much needed a sprocket adapter for my kers bicycle, which website?
Why not weld on a sprocket to a flipflop hub?
Anyone ever find that seller for the tensioner? Can't find them in ebay
