Weird thing happened today had to do a 40 mile journey on motorway in my blackbird engined rush had the car at a steady speed but when i put foot down the car picked up in top gear but i heard the clutch slip the oil temparature had risen slightly it did this a couple of times but noticed when the temparature came down a bit it didnt slip at all i have noticed that the clutch biting point seems to move higher up the pedal the warmer the engine gets I am running an accusump with 1 litre overfill and standard bike oil cooler do you think i should add a bigger oil cooler or add another oil cooler to the system or do you think its something else

Regards Mick

Im using millers semi synthetic

Sounds like an overfill issue... drain some off and try it again.
