| SP it depends on the use. I once had a stm clutch which slipped the moment it was fitted. It came with an alloy basket, which needed replacing after only 1000 miles. I now have a Bucci slipper fitted with carbon plates. To date I have done over 2000 miles and the wear rate and basket marking is very, very minor. The plain pressure plates should be smooth. What is the colour of the friction material on the friction plates. The reason I ask, is that if the plates have been swopped, ( unknown history). The previous owner could have taken out a more expensive clutch and made up a clutch out of used parts? |
