I got my EBC parts from Chapparal online, they are a huge online supply house for dirt, street, atv and cruisers.
EBC sells kevlar paper fiber discs that are for 600 katana that are exactly the same as ours (check part numbers)
or factory type cork fiber discs but impregnated with aluminum.
The standard fiber disc set (8 discs) is $53 and change
The Kevlar is $73 and change
The springs (6) are $6 and change
You need a new side cover gasket $6 and your going to drain the oil might as well due a full change.
Used the haynes manual but dont really need it, the job is so easy.
Im a big guy, 275 pounds dressed out and I like to twist that throttle, the new clutch is AMAZING, did 100 miles last night!
