I have 20,100 on my stock clutch. No slipping at all, but an occasional grab and launch in first gear. never after a fresh oil change, but when oil has 1500 or so miles on it.
I forget, do you have a SP1 or SP2?
edit: I just re-read your intro. SP1 with 25k. mi. Since you don't know the history of the bike (i'm assuming) I'm not surprised about the clutch.
My plan for replacing my SP1 clutch is to install the judder spring and seat for the SP2. There's been a considerable amount of talk about it on this forum. If you search 'SP1 judder' you might find the threads. Just a suggestion...
btw, barnett is way cheaper than replacing with oem.
