My buddy's Kawi Brute Force 750 did the same thing. Too much gas. Like running way too rich.....leaned it out and all problems stopped. Cleaning his air filter helped at first, so I guess the things have a very sensitive air / fuel mix (even more so than normal???) . Try a fresh air filter and naybe lean int out some and see how she does. Good luck
