I am having a lot of problems with my xt550, maybe you experience with them could help me solve my problems. My bike was bogging down when reved up beyond 3/4 throttle. I tried removing the baffle, but now realize I will have to re-jet it or look for alternatives. If you know the of the what size I should set the jetting to, or what I should set the carb screws at, or even just advice on the bike in general it would be greatly appreciated.
