Chain Broke, Any Advice?

[Drewski]

There's one other issue in moving the 4 stroke engine
on its mount, and that is the position is determined
100% by the clearance of the muffler with the down tube. I
barely got the muffler to clear the down tube, and I had
to remove the front fender to accomplish it, so the
position is really not adjustable. I am purchasing a
4 stroke side exhaust to resolve this problem and
make the bike look better.

Interesting photo. I see some muffler mod here.
Never saw that type of muffler on a 4 stroke. You'd
be surprised but chain problems are common to
both 2 or 4 stroke, and they usually have the
same causes like misalignment.
