Yet another chain thread.

My master link failed today. Naturally being a new first build I don't have any replacements yet although they are now on order. The problem I am seeing with the chain they use is that it is too heavy for bike shops to carry and too light for the motorcycle shops. I would like to pose a question to all of you machinist/engine builder types out there. Short of a total redesign of the engine would it be possible/feasible to convert over to a 420 chain? That seems to be the lightest that the local motorcycle shops carry. I suspect that it wouldn't be cost effective but the frustration factor is really high right now so I am looking for options. Thanks! :(

Belt Bearing & Chain on 22nd & I-10 will have the #41 and chain link's. I have been all over Tucson and they are the only ones in town that I have found the #41.

Be sure to put your link on correctly

Is your masterlink facing the right way?
I had set mine up so the open end of the keeper was facing backwards when the link was on top. I thought I had read that was the way to do it. Was I wrong?

Sadly Belt Bearing and Chain has hours that prevent me from ever getting there.

#41 and #415 are close to the same. Same pitch but the width for the #41 is 1/4" wide, and the #415 slightly narrower at 3/16" wide.
I think the masterlink should put put on so that the closed end is facing the direction the chain rotates, so it cannot be driven off.

Yes, you are correct. Both will work on our bikes, some have interchanged links between them. Don't do it if you are not a qualified shade tree cobbler.
