    Ultra top end refresh

    I have my STXR motor out and am going to put in new ring because it is there. I hear about piston problems, do they need replacing or just the rings? Not sure of the hours but think it is under 100.

    Also, notice the side of the case has stress cracking everywhere, I think it is just the paint and will sand on it to be sure. Is this common? Running when removed and all fresh water.

    If I was going to go to the trouble to do rings I would do the pistons too. Less than 100 hours it really shouldnt need either unless you have been running tripples, racing or the compression is down some.

    Just thought since I was there but don't want to waste money. How long do the piston usually go?

    I would be looking arround 150-175 hours as long as the compression is good.
