re-jet problem, two different CO readings from each pipe
I've had a few issues after re-jetting. I decided to order a Gunson Exhaust Gas tester from England. My rear pipe is putting out around 4.1% and the front one is putting out about 1.9%
That gives me an air/fuel ratio of about 13.8 on the front and 12.9 on the rear.
I'm thinking maybe one of the jet needle tubes came a little loose. Or maybe when I reset the PMS screws back to zero, the one for the rear carb isn't going in all the way.
