Spring Return Chain Tensioner

I was having a problem keeping my chain taut, and was very unhappy with the stock chain, so off to Tractor Supply for some #41 chain. Got the chain and got to browsing and also picked up a really sweet ball bearing, rubeer coated chain trensioner, AND spring, it is sold seperatly. After mounting the chain I took some 3/8 althread rod, heated it up and bent it into a U shape to fit around seatpost. I cut a strip of metal ( out of stock tensioner mount) to secure allthread. Then I just mounted the spring tensioner to the end of the allthread, the ID of the tensioner seems to be a good fit on 3/8" rod. Then a little adjustment and done. Spent $40. on everything including new chain. I have put a couple of miles on it an it is a lot quieter, and very smooth...

Great set up! That look's great

That's kind of what I used for my Dble. suspension bike. I do not have pic's of it. But here is what I used. I used a Idler sprocket and had to do some mod's to get it to work with the tensioner. Your set up look's much better.

I looked at those tensioners and was about to order one Fair, when I saw the one at Tractor Supply. It looked like a lot of mods to make it fit my bike though. And the one at TSC was less than $15. with spring.

Yes, it took alot of mod to work, and it was'nt cheap. But at the time I had a nissan timing chain tensioner that I was using. I was taking a trip to Mexico and there was no way I was going alone. The homemade nissan tensioner had a little to much tension on it because that was the only way I could keep the chain to stay on on the trail. And I was afraid to take a long trip with the way I had it set up. So it was kinda of a last minute set up I did with the tensioner and idler sprocket, but it worked great, held up all they way. The chain did fall of several times.
Your set-up is much better and I like it. I was looking at tractor supply but could not find it

Yea I dont see the parts either. looks like they carry them for their line of mini bikes "Baja Motorsports". You could call them. the part # is 165-063 for the chain tensioner, and # 165-280 for the spring...

I love that George thanks for sharing that. I tell ya thats the one thing I hate so dearly on these is that tensioner. Well you know I ditched both of mine but I would rather be running them. Might have to make a trip to TSC and thanks for the part numbers.
Terry

Well Terry your bikes look so awesome this would be a good way to take care of chain slack and be somewhat hidden. The stock tensioners look ALMOST as bad as they work.

very nice mister right. i been in the middle of a move and missed this all togather. i am putting a copy in the clasic posts area
