1200 mk1 bandit. 4900 miles. hi guys. I've just Ultrasonic cleaned the carbs and then fully rebuilt them wIth Keyster kits. IT now starts on the button just like when I bought it in 2000. But.... It will only run normal on 3 on tick over and low revs. On the other cylinder it pops and fires occasionally. On run down, out riding it pops and bangs. If I giVe it some revs say over 3000rpm the problem cylinder kicks in. Full beans and it's fine al the way up to the red line, pulls like a train . As the coils fire two cylinders I am puzzled. Could it be a dodgy hit lead? Or a dodgy Spark plug (already fitted iridium) ? Or could it be the slow running jet? ( which one is this?) All jets were changed during rebuild. Could it be an air leak? could it be overfueling?
Any ideas very much appreciated, I'm near Gatwick?
