[QUOTE="FullMetalFabworks, post: 451170, member: 5910"] Not a problem, I don't have any suggestions on the billet motor mounts but they're definitely a good idea. I don't race mine ( because it costs too much $$$, I might do KOH next year if Polaris offers up another new one as the prize again haha), but I have almost 1,500 miles on mine and my buddy has nearly 3,000 on his (both he and his brother race theirs) and probably 80-90% of those miles are at race pace so between the two of us I think we have a pretty good idea of their weak points. Another thing I forgot to mention that is an absolute must is changing out the Secondary Clutch dampener from the powdered metal crap that is in there to something like this one from Sparks racing [url=http://www.sparksracing.com/heavy-duty-secondary-clutch-dampener-polaris-2011-2014-rzr-900-xp-xp4-1000xp-xp4.html]http://www.sparksracing.com/heavy-duty-secondary-clutch-dampener-polaris-2011-2014-rzr-900-xp-xp4-1000xp-xp4.html[/url] Those usually go before the 1,000 mile mark, I pulled mine out in two pieces at 700 miles, and they take out a lot of expensive parts when they go.
