| Could be the same problem that Banger San (Andy) maybe suffering, we were discussing it at the bike night on Monday. He suffered clutch slip at Oulton and one of his winter upgrades was to fit a later master cylinder.
These are often smaller than the original dropping the piston diameter from the original 13mm down to 12mm. Andy was saying he was getting more clutch drag when the bike was in gear with the clutch disengaged. This may well cause more heat to get into the clutch and could effect the steel drive plates, check to see if they signs of hot spots (brown patches)
