I thought my clutch was going out in my 88 cr500 so i took the pack out and inspected and the disks and friction plates were well within spec but a couple clutch springs were broke and very weak tension on the rest So i purchased the EBC springs installed them and its eye blurring acceleration again!!! Just friggin stellar, its got a little stiffer clutch pull but i got use to it very quickly, Oh boy i am happy i got these springs.
