ok guys...i'm new to the XR world. i race mx and hare scrambles. i'm currently in school and work full time so my time is pretty limited as far as riding goes. i have i decided to pick this up to rebuild and race in the vintage class in our hare scramble series. should be a blast... any words of advise? any issues i should really be aware of as far as the 86's go? (i heard 3rd gear is a downfall) good places to get parts for these? i will be stripping it completely down, powder coating everything i can and wanting to make it raceable. it is not clean and it doesn't run. the guys says it needs a new coil and fresh gas and it'll start right up...but that seems pretty hard to beleive. i noticed was return spring on the kick start is gone...i've never tried kicking one of these over but common sense would say it's a beast. i mean it is a 600 lol... i also noticed the chain guard (case saver) is missing and the case is cracked where the bolts would screw in... i'm currently in the process of rebuilding a 125 so i wont be able to start digging into this thing until i get my work bench cleaned off. again, anything you guys can think of would be awesome!
