A riding buddy of mine just picked up a 02 XR650R and wants me to do some basic mods to get the bike to start better and jetted correctly. I have'nt seen the bike yet, but he says it's in great condition with under 500 miles on it. I'll pick it up this weekend and thought this would be a good place to look for info. His biggest problem is hard starting, I've tryed to explain the 4 stroke starting routine!!, (he's not a mechanical type of guy), so he's abit frustrated!. + he lives in a very cold & wet area. I want to to start with the basics, (the bike is stock), so I need need to know what can be done with jetting, 3000' up, airbox mod,s, mod,s to stock exaust, starting routine ect., any info would be appreciated.
