help, chain, sprocket

depends on the bike and wheel. Mine is curved in towards the wheel. I'd flip it and give it a shot.

HI,

Have you beveled the teeth on the rear sprocket?....That will usually do the trick assuming you have no stiff links in the chain (the chain line is generally pretty close in most installs and you wold be surprised how far off it can be and still not cause a problem)...

Try beveling and I think you will be happy....(Pic below to show you what I mean....see how the sides of the teeth should angle in on both sides?).

Hope this helps you.

Good luck in your build.

Thanks, JasonH and Andrew. My next step will be to turn the sprocket over. I'll also do the beveling. I'll let you know how it works after these changes. Wish me luck.

I did'nt use a tensioner either and I did run into the same problem as you. I did get it to work out by dumping the outside rubber and using a rubber washer that just fit perfict over the hub that I found at True Value. it gave just the right clearence from the chain. These guys seem to know what they are talking about so I'd try their remedys first.

I think the kit Chain/sprocket set up is junk. The chain is made of rubber and chewing gum and the sprocket mount to the spokes is acceptable at best. Sure it can be made to work but it is a major source of problems. Since I switched to bike chain a little break in (maybe 10 mi) and now it doesn't stretch and it weighs 1/3 of the kit chain. Also I can use a 1/2 link to make both my chains tensioned at the same time. I'm Also opting for rigid sprocket mount to hub on HD axles and HD spokes on HD wheels. The drive system is the only thing I've had repeated problems with.

Does a Bike Chain fit the sproket? what size? Whats a 415chain?

Dish side in. 415 chain was hard to find. 41 chain works very well and cost less.master links can be found at lowes. try a lawnmower or tractor shop for chain. got mine from Gerish bearing. the center of the sproket needs to fit over your hub. File and moto tool do the trick. Somewhere saw a post on wiring spokes together to so they can take the strain thats put on them. check the posts use search and you will find all sorts of good info. hurry the rainy season is almost here

Cool
No need to worry about the rainy season. It doesn't rain all that often in So Cal.

Yes, a BMX chain 1/2 - 1/8 is the size. I use a BMX YBN(Yaban) half-link chain. It's light, and the most durable I have encountered. Be warned, this chain enjoys breaking your chain breakers. I used a motorcycle chain breaker, and it also got broken. A 415 chain is commonly used in go-karts, tractors and some motorcycles. You can easily get 415 chain in motorcycle spare parts shop and tractor parts shop.
