clutch weirdness

[Church6360]

ok, when cold my clutch lever must be almost fully released before the clutch grabs.
and when the throttle is abruptly opended at 5k ish, it slips a little.

after about 7 ish min of riding (i.e. nice hot engine ect...) the clutch no longer slips, and engages somewhat sooner, like maybe 3/4 released.

and when warm, with the clutch pulled all the way in, in first gear, if i rev the engine above 2k i feel a slight tug, as if the clutch is grabbing, slightly.

the clutch cable is new, and the handle bar adjustment is adjusted all the way in, and the engine area adjustment is all the way out, don't have my manual at my apartment, so i forget which way does what on each.

the clutch is only about a year old, but endured a decent ammount of slipage as the old cable was ending it's life.

it has also endured some other foolery such as burnouts and horseplay like that.

and a little bit of 2 UP with 2 fat people on it.

My first thought, my poor mistreated clutch is losing it's edge, and should be replaced.

NSP noticed my oil was low, so i added a quart, and at first i though that had fixxed it, but i seem to have been mistaken.

anybody care to take a whack at what this problem might be?

Hi there, did you check the oil again? (maybe one quart wasn't enough?)

oil level and a warped disc. btw I have a spare set of discs if your interested.

[Church6360]

just checked the oil, looks full. i may be quite interested in the disks davipu.

what causes them to warp in the first place (heat i assume from clutch abuse)?

[davipu]

heat , combined with low oil. the only direction the metal can expand is to warp out of plane

damn, one more excellent reason to check my oil level before each ride.
