I ordered the compensator upgrade kit & with over 20,000 miles on my bike should there be any parts that I should replace while I have everything apart ? I would just as soon replace parts now then have to take everything apart in a few months . The starter in the bike has been replaced around 16,000 mi & I still have starting problems that is why I am putting in the compensator kit , hoping that will cure the problem . Both starters made a grinding sound @ times like the starter is not engaging all the way so could there be damage to the ring gear ? I think 103" stage 2 kit may be hard on the starting system because the heads did not have compression releases installed .
