I've noticed a little clutch slip over a year ago. Typical stuff some slip in 6th gear when powering on. A few months ago it got noticeably worse, but still I delayed. About a month ago I noticed it would slip when shifting into 2nd gear.
And last week I couldn't even do 2nd gear power wheelies.
Enough!
Today I finally put in new friction plates.
It took several hours. Getting the old gasket off the case cover was the hardest part.
Holy **** what a difference!
It's like somebody gave me 20hp for free!
Why do I procrastinate and wait so long!
Now I just hope I don't highside myself with all the new power.

The bike currently has 64,000 miles on it.

 

64k, was that the original wheelie abused clutch?

 

yes that was the original OEM seriously abused clutch.
I should have replaced it at 50k, but I've been milking it, and slipping it for an extra year or so.
