OK so I am finishing up my clutch job, new disc, drilled weep hole, and replaced the transmission seals.....and YES the output seal leaks! Not while running mind you but after shutdown. I still have the swingarm off just to make sure all was well and it isn't. I did fill the trans up with synthetic 75/90. So tomorrow I will be looking for a different seal than OEM. You can actually SEE how poorly the seal fits around the shaft. Should I use a different fluid for the trans??
