i have my baffle out on my 06 and i havent jetted. It runs fine but when revving it and when i let of the throttle i hear this high pitched chirping noise. It sounds like its coming from the exhaust, but i have heard its the slide in the carb. tell me what you guys think, and if yours does the same.

thanks

i think you should just jet the bike it would be alot better
