    Ski broke-in using learning key

    I am following several leads to purchase a used 2008 RXT. Found one guy on Craigslist that claims he broke his ski in using the learning key for the entire 10 hours. Could this have damaged the engine permanently?

    Note: The ski still has 3 years left on its extended warrenty, and the current owner claims it is in perfect working condition.

    I dont think there is any damage done but it will not be broken in @ 10 hours using the learning key. Need pleanty of good hard full throttle acceleration runs to seat the rings properly.

    That's what I understood as well...But shouldn't a WOT run be done in like the first 30 minutes for the rings to seat properly? If this guy never gave it a full run until after 10 hours, is it already too late?

    I wouldn't think there would have been any damage done to the motor a I have read about several people who wrongly brok their skis in this way on misguided advice. The motor just mightn't be quite as strong or a quick as another motor that was broken in properly.

    The same thing I heard from other engine builders.

    All good advice on this topic!

    I'd be more concerned about pump tunnel stress cracks on that 08 TX, lots of us had nightmares with this problem!!!!!!!!!! Take the grate off and do a very thorough inspection, if you see any I personally would walk away!!!!

    If none, I'd reinforce the tunnel. Lots of threads about this subject.
    On the break in, if owners would just read the friggin owners manual they would see the proper breakin procedure. There are some real idiots out there giving poor advice!
