| 800ss clutch slip probs
Not strictly DD but, as an 800ss has a wet clutch pretty similar to a 620s I thought this would be the place to ask.
I was practising at Croft the other day when towards the end of the day I thought I was detecting some mild clutch slip in the higher gears when winding it on out of the faster corners. It was a very hot day with the oil temp up around 140-150 degrees C.
The bike runs on 15w-50 semi-synth and has done two full days at the track including the day in question. I've not done any fast starts or race starts so, I would've expected better than this. I drained the oil today and it was absolutely minging - black. Again, that surprised me given that it has done about 200 miles. There was no debris in the oil or the strainer.
I'm racing the bike this coming weekend so, I don't want to get caught out. I have a spare clutch in a spare engine and I can always rob the one out of my 800 road bike as well but, I suspect I would face the same problem again.
Has anyone else experienced this with the 620s and what have you done to cure it?
