I have a '87 XR600 - dual carb - owned it for a few months, and have been having some issues with starting this beast when cold (40F). I replaced the factory stator with one from Ricky Stator a few weeks ago when mine died. It made starting easier, but it's still a bear. I have tried the pull decompression lever and kick 10 times, then find TDC, push past that a bit and kick, and try again. I've also tried the above, but without the decomp trick. No luck. Even just kicking it over and over, just makes me tired. I noticed that when I have the choke on, I get some fuel on the ground from the overflow(s); no overflow with the choke off. It seems to start, after a while only with the choke off. When warmed up, it starts first kick. The plug is nice and dry, light tan, no fouling, gaped correctly. Nice healthy spark. The valves are adjusted in acordance with the factory manual as well. Bike has good compression. It has a Super-Trapp and a twin-air filter. So whats the secret? My old TT500 was a breeze to start compared to this.
