Hi all I just got an 88 xr 600 saturday. Have ridden it a few times, but just got it registered and street leagal. Anyway, it has a piston and cams upgrade that I know of. I started it today and took off for work and it just died. Funny bit is it idles just fine, any throttle at all and poof it kills. I bought it from my neighbor and before he sold it to me, he told me it had done this to his son. He put a new pick up coil (heard somewhere that it was a common problem) or the likes in it and had ridden it a few times, as have I,-- no problems and assumed it was fixed. Does anyone here know what the problem is or where I should start looking?
