Inner primary main shaft seal
How difficult/complex is replacing the inner primary main shaft seal?
I've developed an oil leak, and I'm pretty sure this is the culprit.
complex job? need special tools?
I do have a manual, forgot to read this section last nite...
Thanks

Well, you have to pull the clutch and compensator so you'll need the sockets for that, something to lock the primary chain with, loctite and a torque wrench for reassembly and I find an air impact really useful for removing the clutch and compensator!

Pretty straight forward job, no special tools needed. Remove the outer cover, pull the clutch, compensator and primary chain, remove the inner primary and pop in a new seal.
I'd replace the shifter shaft seal while I was in there....Then put it back together and go for a ride.
For someone that's familiar with the job it takes about 2 hours, for someone that's never done one, plan on 3 to 4 hours.

Get a strong breaker bar and a cheater pipe, works without causing harm.

YUP! Good advice. Read the manual, take your time, don't cut corners. These thangs aint rocket science, you can do it.
Once you've removed the inner primary, dont forget to check the race and make sure it hasnt walked toward the pulley. If so, all your hard work and new seals will be futile.

Good advice, I usually just replace the whole mess with the Baker inner primary bearing set up, it's a much better design.

Check your belt and your final drive pulley teeth while your in there. If the pulley teeth are rounded off it will strip eventually. I've seen it happen to 2 friends while we were out on the road. Those guys ride hard though. They had to get picked up.
Incidentally, make sure you don't over tighten your belt. That can be a root cause of seal failure.

aw crap.....this may be self-inflicted then.....when I took the rear wheel off earlier this summer, I adjusted the belt tension per the manual (up on a lift). when the bike was back on the ground the belt felt a lot tighter, but since the manual said to adjust the tension on a lift, I left it....
