Default Re: chain

Don't know if W.W. Grainger sells in Canada or not but they're another source for industrial #41 chain.
As for your chain jumping off, make sure your alignment is good. The tensioner, if you're using one, must be aligned with your engine sprocket and the one on your rear wheel. Misalignment and too much, or too little tension can cause your chain problem. Also check that there is no binding in any of the links that keep the chain from tracking over the sprockets smoothly. I've seen a couple of those Chinese 415 chains that had a twist in them and rollers that didn't roll. Industrial grade #41 chain is the best way to go. It runs true and it won't stretch as readily as the kit chain. Good luck.

I'll echo 2door. Your chain stays (frame from cranks to rear axle)come back unparallel to the chain so ya gotta tweak it (the tensioner bracket) a little!

Kit chain is made from caramel & chewing gum.

I'm a big proponent of being a kit chain opponent! I have a track (bicycle) chain on my 2 stroke and it hasn't noticably stretched in 100ish miles. I'll buy a few front sprockets and face them off for 1/8" chain.

Feel free to pm me if your interested.
