Only 2 things so far. Master cylinder for front break started seeping and ate the plastic coating of the cover (I believe a service tech either over or under tightened the cover bolts). Had the part replaced and checked the torque myself when I got home. Also, my inner primary started leaking and I had to have a seal replaced on that (took a little time finding that one - I thought I might have either a bad gasket on the primary drain plug or a crack in the case there).

 

~6 mos. of ownership @ ~8500 miles mix of short hops and long distance

-1 ea front engine mount for improper fit and resultant fatigue
-1 ea rear engine mount for rubber fatigue
-rear shifter arm was partially off of pinion (the one that goes into the transmission--a pain to get to) which trashed the bolt from all the vibration, fixed this myself by purchasing a new grd 8 bolt from the hardware store, suprisingly pinion still looks gtg
-plastic anti-rattle clip for the clutch lever was worn down to the point that the clutch lever rattled like a machine gun--a $3.00 platic piece the size of your pinkie nail--got for free under warranty--booyah (haven't put it in yet I'm saving it for later)

 

Anything could happen with mechanical stuff at any time
weight the cost how much you trust your bike wont break and roll the dice or play it safe
