Hey guys my rear sprocket has always been slightly mis-shapen so the chain varies from loose to tight with each revolution of the rear wheel but just tonight its gotten sooo bad that the chain goes from .5" of play to 3" of play, I leave friday morning for the biggest event of the year and I need a quick fix, it is possible to run the chain tight enough so that it works but Im worried about damaging the clutch bearing on my Horstman greased lightning or even worse snapping the crank? Should I just run it tight? Would a spring loaded chain tensioner help? PLEASE HELP ME I CANNOT MISS THIS EVENT ITS THE ONLY MINIBIKE EVENT OF THE YEAR!!!!
