Would you be able to use a long bolt through the chain guard mount? Then put a nylon sleeve over the threads with a nut on the end for the spring attachment point? Would this be too close to chain movement?
I cut the 5/8 tube 10 .125" eliminated nuts..installed 10 x 1.25 Helicoils... then made a cam shaped Spring holder with 3 holes. Removed Pulley bolt...rewelded opposite direction...bent everything opposite of how it was made..flipped spring over so now tensioner pushes up! Works great! 5/8 bar is now locked in won't spin and used original spring! Great idea I just made it better!
Nice! I ended up putting a different spring on there and doubling it back around the swing-arm and back onto the tensioner arm. Works great but after that plastic wears down it gets pretty loud. Might just go to a metal roller but I bet that will be even louder. Maybe a roller skate wheel or something would hold up, not sure. That plastic lasts for about 10 miles.
@@johnhock890 Yeah I needed quite a bit of tension for it to not oscillate up and down at at over 40 mph. I think a skateboard wheel might work better. Not sure if it'll fit on that tensioner though. Maybe just a metal roller would work, but it would be loud!
www.gopowersports.com/coleman-chain-roller-assembly-for-ct200/ I have been using these and don’t think they are too loud at all. I like them because they are a little wider than the plastic ones. I am also working on an updated tensioner that is even beefier.
@@idiot-proofgarage3739 Nice. I see those bearings have 8mm ID. Did you have to use different bearings? EDIT. - OIC it looks like they use a spacer to go down to 8mm. 👍 I’m thinking about trying a sprocket too. Maybe the stock 10t from TC. It works great as is but wears the plastic rollers too quick. Maybe that metal roller would be fine though. I put some dynamat type stuff on the tensioner arm today and that helped a little with the noise. 🤷♂️😆 Noise only happens when off throttle though.
Ride it for about an hour and you will have worn through the tensioner wheel. I got the same thing for a mini bike and was very disappointed that the spring is essentially unusable in most applications, and the wheel doesnt last at all, im currently using that arm with a solid slide adjustment I made for it and an idler sprocket instead of the wheel but it knocks the chain off on big bumps. I need a spring tensioner with the length of this and the functionality of the Craftsman sprocket tensioner
@@lowlifeslides9918 The cool thing is you can use the metal roller from any old Coleman minibike jackshaft setup. It fits right on there. I used the bearings from the plastic roller and a washer as a spacer tube extender. All stuff a lot of people have laying around. The metal roller is so quiet too, opposite of what I thought would happen. Might want to try it. I think a sprocket roller might be cool too.
@@bwxmoto Ive done something similar to what you have now but with a sprocket, it has been holding up alright but it vibrates a lot. I thought about trying a metal wheel but thought it would cause wear. I might have to try that coleman roller tho, itd probably save me 90$ on the craftsman tensioner
I’m glad you addressed this, when I test drove mine for the first time the chain popped off. Couldn’t tell how it happened at first because the chain seemed so tight when I put it back on, then loose while rotating like you pointed out. Are you getting a longer chain to help fit the bigger shocks?
Not for that, but for the 60t rear sprocket. But if I was leaving stock sprocket and just upgrading shocks to longer ones I'm not sure if I'd need an extra link or two or not. I'm guessing I'd need maybe one at least but that's just a guess. And I have seen many people have issues with chain tension on these things stock over the years. My chain didn't come off but it was rubbing on inside of driven pulley bad a few times and it sounded like it was going to pop off. I think chain tensioner would help that! I'll know soon. 👍 Might also need a spacer between sprocket and driven pulley too though.
I built one of these and they work great thanks, but I'm having a new problem. The rear driven pulley is terribly cut and bent from running it without the chain tensioner. I was Looking to get a new one and noticed in the video you said you replaced your old one, so wondering if you recommended anything.
Yeah you can buy just the rear pulley, at least you used to be able to on eBay and amazon. It would be listed as the “driven pulley” for a TAV2 30 torque converter.
Real nice idea and like you say, should have come that way stock. Try not to overdo it with spring tension. Find the happy middle. Are you going to do a vid on the 60 tooth install, etc?
Yeah isn't that just so slick? Like I said, wish I thought it up! I have never really dealt with chain tensioners before so I'm going to get a bunch of different springs to test out. Hope I can find some locally that will give me enough tension but not too much, like you said. Also I have been working on vid for the 9t/-60t (or 8t if possible) setup but I ended up having to do the shocks and the tensioner, chain obviously, and also driver pulley and everything at the same time. Also trying to measure everything so eventually I can cut off the driven pulley shaft mount and use a regular TAV plate. But yeah hope I can make a vid about it all that makes any sense. LOL 😆 Also got that front brake kit / stage one kit, and some other stuff. This mini bike is going to be pretty cool when it's done!

The only other thing I did was bend the chain guard mount where the spring goes. Just so the chain wasn’t so close. But that’s easy. Nice video.

Thanks! How long of a spring did you end up using? just curious. I have to put bike back together and then try to find a good spring for the job.
