Top end rebuild question

[rags319]

Have my 2011 apart. Should i replace top crank arm needle bearings. Also what gaskets/orings should I replace with new if any. Sled was apart last year and they look alright. Thanks.

If the bearings look fine, I wouldn't bother replacing them. Doing a top end rebuild on mine as well, wont replace the bearings.

Replace all of the gaskets and o-rings you remove.

replace them! they are right there! think about what they do. every time the engine fires it smashes down on those little needles, its only a few bux more and again they're right there!
