[QUOTE="Morvo, post: 1229411, member: 64644"] What makes you suspect you have a crank seal failure? I doubt there's any bike where you can remove a crank seal without splitting the cases apart. Sure you could pull out the old one using that method but how the hell are you gonna get the new seal in without warping it? As for rebuilding the lower end I would be tempted to leave everything else if they are within their tolerances. I might be tempted to change the crankshaft bearings but on a bike as new as yours I doubt they will be shot. Just change all of the usual gaskets and seals and put it back together. [/QUOTE]
