Well the zx9rE trackbike is looking good after a paint job, general tidy up, and a bit of pinstriping.
At Hidden Valley on the weekend, it developed a misfire on partial throttle, and at or just off idle. Once the throttle is opened wide, there is no problem, it is only partial throttle ,coming out of corners, or rolling into them when the miss shows up. Anywhere above half throttle is good, under that and it sounds like one or two cylinders are dead, and there is a lot of backfiring going on that wasn't there before.
Any ideas???
I don't want to go tearing into it,pulling off the tank, airbox and carbs only to learn the igniter or some other part is a known fault[:o)]
Thanks in advance
