Clutch lasted on trackday
So I have a 2008 CBR600RR fully race bike with an STM slipper clutch, and back February at the first CCS RACE my clutch started slipping ( you could hear it). After that weekend I took the bike to my mechanic and we decided to install the EBC heavy duty kevlar plates (supposedly they are HEAVY DUTY). Two weeks later, with a brand new clutch, I took my bike to a track day, with no launching or grid starts, at the beginning of the day I could feel and hear the new clutch slipping ( Not sure if its "breaking in" or its just not normal) but as the day progressed it stopped slipping.
The trackday ended, I parked my bike home and it stayed there until the next race.
When the next race weekend arrived I pushed my bike down from the stands turned it on, got into first gear, and let go of the clutch and the bike just stood there motionless and turned on (while in first gear). My mechanic later came and we took the cover off, and the whole cassette had a little free play, once taken out both disk and plates were glassed (useless)
What could have been the cause for the clutch to go bad in one trackday?
bad installation? not soaked enough on oil? is it even possible to be that bad of a rider to glaze a clutch in one trackday?
I just want to know since he's trying to charge me for the whole clutch & disks set again.
thanks in advance
