I've got an fzr250 which has been having some problems lately. It rides alright until about 7000 rpm (redlines at 13500) and then bogs out. I thought it was the carbs at first that needed tuning, but the've been balanced, cleaned and put back. It is still doing it. When it idles, it purrs nicely, but it just is unrideable at the moment. When it bogs out, it the revvs jump down and it looses alot of power. I've personally given up on trying to fix it with my limited knowledge of bikes, and was wondering if anyone knew of a mechanic that has experience working on FZR250's or the like.
