    Has anyone moved the small chain sprocket (Clutch Gear Drive Sprocket behind the chain wheel cover )out about 1/4''to help clear a larger tire and a custom motor mount that the chain is rubbing against ???

    I've gotten about 1/16 by cutting a small slot for the key in a washer to stack behind the sprocket

    maybe more could be gotten by removing the lock washer under the nut and moving out more, but I wanted to get the nut fully threaded on - and how much grab the sprocket has on the key is important too

    no. You need to take a ******* (a file) and file down the spot where the chain is rubbing the engine or chain wheel cover.
    Just dont file your engine much. Dont want any structural integrity issues.
