Aftermarket Clutch cover or crash protector for stock cover
Billet short levers - ASV, CRG, pazzo
OEM stepped front Fender bolts
Stock fairing stay
Salvage or scrap title SP2 frame (scrapes are ok but must also be in good condition)
Battery mount: Thorsten Durbahn is the only one who makes them
Front Axle sliders: supermotoengineering.com used to make them, last time I checked their website was down though. R&G also makes them.
Attack rear sets and triples can be purchased directly through attack racing
Rear hugger: tygausa.com has an SP2 one on sale for $85 right now
Billet clutch cover: EDR makes one, as does circuit 1
Ceramic rotors: brake tech is the only company I know that has ever made them. They have been out for some time. They are currently working on a new formula or having issues with a supplier or something.
Slipper clutch: yoyodyne or JTR, not sure if either still makes them
Forged wheels: you want magnesium or aluminum? There have been about 5-10 sets of various brands/prices that have gone through the forums in the last year or so.
Master cylinders: probably won't find those for sale very often, but you can troll other forums as they are all the same.
Dash: I'd be surprised if you ever found those used. The amount of work to install them, and the purchase prices pretty much negate any chances of finding them used for a good price. Just bite the bullet and get new ones. Don't risk buying used electronics, too many things easily broken.
This is the best place I have found for new OEM parts: http://www.cyclecentralpowersports.c...2003&fveh=3622
