Ok, first post, been a forum pirate for awhile now, jus sort of lurking as "anonymous", until NOW! Finally back into the dirt bike world. Picked up on a 2004 model honda crf50 for a christmas present for my boy, going to get it in tip top shape between now and dec. I havent had a chance to mess with it yet but the previous owner informed me of high rpm bog. Does this sound carb related? And what are some specifics as to would could potentially be causing my problem. Also, this bike has 88 (which im really not positive of what it includes) kit and honestly thinking about it now, im not sure what exhaust, and a new carb. And should i assume the carb should probably be jetted differently? Not very familiar with any of this stuff but realllly enjoy dealing with it. Knowledge is everything for me at this point. Thanks for any reply, uin advance. Kenny.
