pikey

Hi i have a 2005 1200 bandit which had a scorpian end can and a kn air filter . This combination has made the miss fire in the carbs really bad and trying to keep the bike at 30mph smoothly is imposssible. After reading on the forum i replaced the air filter with a standard one which made a slight improvement so i have shimmed the needles by 0.5mm and balanced the carbs which has made 70% better,the air screws have now been backed out 3.75 turns out from being fully in this has made the bike the best it has ever been.The exhaust still pops a bit when you are off the throttle but not to sure if this is because i running with the baffle removed
