New clutch drags when hot

[jerryz]

fitted a new clutch to the S4 its fine when engine cool but after half an hour it drags very badly so gear changes are a nightmare , have bled the slave silly and its new as well , adjusted the levers and pivots but nothing helps, as soon as the bike cools down all is well until it hots up again,

plates and dixcs are all in correct order ans stack is within limits so I am now not sure what to try next. also fittrd an new clutch throwout bearing .

Bleed again, and tie the clutch lever to the grip over night, you still may have some air in there.  The clutch may also just need a little break in time.

+1 It really sounds like there's air in there - or maybe not air but the fluid is water saturated. When that happens the water will boil out and make tiny pockets of very compressible steam. When the bike cools, the water is in it's much less compressible liquid form.

I'd bleed/flush and make sure that you have replaced all the old fluid in the system with new freshy. Make sure you drain down the reservoir as low as you can, with out sucking in air, before adding the new stuff.

New fluid in the clutch slave system and i have bled it now for 3 days tied back to the bar its the first thing i did but still no good

Slave cyliner was new last year and so was master ,, went for a 50 mile ride today and all seems fine now but dont know wether it was the bleeding all night again or the shims on the basket bolts that cured it or both.

clutch seems sweet now

next job check TPS as slow running a bit off

I had a problem with mine where the adjustor screw on the lever backed in, defying gravity.  these bikes shake so can't rule out anything
