Default Re: Shifter Kit Tensioner and New Front Mount

The usual problem with the jackshaft to chainring chain loosening is due to two reasons. 1. the engine twisting and 2. the engine slipping on the seat tube. The engine twist as stated in the manual will stop after a ride or 2. The engine slipping on the seat tube may never stop. This is why we created the chain adjuster. It make adjusting the chain easier and holds the engine in place and keeps it from slipping on the seat tube. It takes less than 1/16 of an inch of movement for the chain to go from tight to loose. A chain tensioner may work but it really isn't solving the problem. Hope this helps.
Design is easy, execution the hard part.
