Running in after Re-bore mileage to be done ?



  • Hi All
    So just Rebuilding after re-bore and mechanic says 300 to 500 miles is that the Norm ,seems a lot.to me, also said to start and warm up to normal temp then stop (do this twice) which sounds a good idea, whats everyone's thoughts



  • I always feel that would you really feel comfortable riding a bike flat out only having tested it with a warm.up warm down procedure.

    There are other reasons why you should run an engine in. Piston ring and cylinder wall glazing can occur if you don't follow an appropriate run in procedure.
