Make sure it is adjusted for slow speeds, this is very important when using a shorter fourth gear. Another possibility is to remove the goggles, this will free the flywheel, but make sure the cam is adjusted!:-) Michiel Fokkema John Collier wrote: > As you all know I am building up a 125 engine using an ETS cylinder, > piston, head and a 100 sport engine as a base.
