Sorry to hear about the crash. I have had good luck w/Applied top triple clamp and Pro-Taper handle bars. The clamp allows for quite abit more adjustability (farther forward + higher if you go w/the 5mm or 10mm higher clamps) & the bars are generally bulletproof. "If you bend Pro-Tapers you def crashed way beyond the norm." Regarding the radiator, if you are buying a new one try Tracey's Yamaha Parts warehouse 1-800-860-0686. Their prices are generally much better than the local dealers even including the shipping. I also heard that Motoworldracing.com had good yammy prices. Once he gets the new rad, tell him to invest in some rad braces or guards. Works Connection ($50) work good for moto & I think DeVol and ZipTy Racing offer more enduro/hs/offroad versions. Cheap insurance if you ask me. Good Luck!
