It's not all that tough of a job. I had done 2 stroke top ends but never touched a 4 stroke. I don't like anyone touching my sled so tackled it myself. Like Doc mentioned there's a great couple videos on SXS blog showing tear down and rebuild on a 998 yxz engine. I may have even posted a link in my stage 6 build thread.

I'll give it a shot when things start to warm up.I've fixed 998s that run "only" about 14-15 psi boost where I could tell head wasn't sealed completely. IMO, knowing what I know now, I'd say head studs on anything above 12-13 lbs boost. Stock torque-to-yield head bolts just don't provide enough clamp force for me. But, ARP head studs do.
I have to laugh! The timing mark setup is exactly like my 150cc scooter.
I'll double check that thread. Thanks, DMCIt's not all that tough of a job. I had done 2 stroke top ends but never touched a 4 stroke. I don't like anyone touching my sled so tackled it myself.
