Clutch kit there Charly for all the reasons outlined above , but ya might buy time just
going easy on her until you get your kit in August

use a 20/50 weight in the mean time might help a "lil' " bit

Sounds like somebody put energy conserving "stamped" moto oil in there and the plates
have become glazed as a result ....imo

Just a thought - one of my mates was complaining about clutch slip at high rpm's a while back.

I rode his bike and couldn't feel it at all.

Turns out he was sub-consiously squeezing the clutch lever when warp drive kicked in at 7K.

A slight change of riding style later and no more clutch issues.

mine does slip at high rpm and its for sure not me grabbing the clutch because i dont leave any fingers up there unless i anticipate the shifting. the majority of the time it slips, i shift, it slips, i shift, then it goes.

Try a set of +10% harder springs in the clutch - slightly heavier lever but quick to fit and pretty cheap.

I'm pretty sure the springs in my Goodridge kit are a bit heavier than standard too. I really didn't notice any difference in lever pressure but our bikes have a nice light clutch so 10% like Dean0's suggesting can't hurt. I can redline in first, into second full throttle and keep it pinned wide until I do the same into third. Zero clutch slip...and good harmless fun. The front gets a bit light though.

It's probably cheaper in the long run to buy plates and springs as a set but clutches are another thing that I'd never buy cheap makes (like tyres and chains). I think you get what you pay for in some cases.

i am soo happy the scuff and clean and soak in the correct oil did it its a night and day difference no slippage and all power in the powerband i am still planning on getting an ebc performance clutch kit with springs and steels in august but hopefully this will work until then
i really wasnt expecting that to work but it did if there is anyone else with the problem of running the wrong oil then their clutch starts slipping just soak everything in coleman lantern fuel "aka white gas" and use like 80grit sandpaper or concrete to scuff the plates and steels lightly then let soak for like another 5 hours and when you take them out you will notice that the color will change from a glassy black to a dull gray then use a toothbrush to make sure you get any and all grit off the plates. then soak in the correct oil for like 6 hours and reinstall.
anyway thanks again for all the ideas their priceless
thanks again
james
