I put a full yoshimura RS3 Comp pipe on my bike, dynojet stage 2 kit, and put the pro design foam intake with billet adapter. the bike idles fine but as soon as i put it into gear and start to let out the cluth it seems as if im lacking fuel. it bogs down and sometimes stalls. if i stay heavy on the gas then it seems to be fine. but i would think it should be easier than that. when i do get it to take off and take it for a short ride it also seems as if im lacking low end power and the power doesnt seem to kick in till high RPMs. when i let off and decell it back fires and pops a few times. i pulled the plug and it seems to have carbon on it and the post in the middle looks as if its a light grey maybe white. i am running 146 and 148 mains and have the new DJ needles installed with the the clip in the 5th position out of six. im sitting in my garage with it apart so if you guys could chime in and help out that would be great.
