A little off topic but I wanted to see what you guys would have to say. A friend serving in Iraq asked me to keep his bike running while he was away. It leaked gas all over my garage, so I drained the tank and just this week got around to cleaning and rebuilding the carbs with new orings and needle/seat. Seems to have beaten the leak, but on to the problem. The rpms hang up around 3-4k. Then when letting out the clutch, pulling the engine down the r's slam down to the 1300 range and stay there. Run up through the gears and the r's hang up again and pulls the bike along untill you drag the brake, lug the engine and then the r's drop again. I asked the owner about it and he claims it has done it for a while and stops when it warms up. I havent been able to flog it for any length of time yet. Any thoughts?
