Just bought a non-running '02 125. I know thats always a huge gamble, but for the price I picked I got it for it will be hard to lose money on the deal. Anyway, when I first picked it up it wouldn't even fire no matter whether I was kicking it over or trying to bumpstart it. After cleaning out the carb a bit and installing a new plug I've gained a little ground, but not much. Still have no luck kicking it over, but when I bumpstart it now I can get it to fire a few times, and on a few occasions I have even gotten it to run for about 50 yards, however with anything less than full throttle it dies and even under full throttle it is not making much power -- probably only going about 5-8 MPH. After these runs the vent tube running to the float bowls pukes - so I'm thinking I need to adjust my float level? Just not sure if the float level being messed up would cause the engine to have so little power. Guess I may have to start looking at rings, too. Just hoping someone here could point me in the right direction. Also, if anyone knows a good resource about the Mikuni carb thats on it that would be awesome as well. I sourced a manual for the bike online but the only picture of the carb is an exploded assembly view and its hard to make out the individual parts. Thanks!
