I need some help with the clutch. Will a 89 and up clutch fit an 88, or is it a one year wonder like the cylinder? The part numbers are different on the OEM fiche, and Rocky Mountain lists clutches for 89 and up, but not 88. I can buy an 88 clutch on eBay, but the selection is limited and they are pretty pricey. I realize I probably need a really good clutch for that much power, but I don't want to overspend on a bike that is not going to be raced. Thank you for the help!
