Hi guys,
Been lurking for a while, first post, and I need some help. I'm running a Jaguar CDI, a high comp head and I have done some mild porting, widened intake and exhaust, took the piston and matched the skirt to tdc on the intake, and relieved the piston to match the exhaust port at bdc. If I raised the ports any, it was minimal. The widening was also mostly minimal. I am using my Jag cdi as it came in the mail and the problem I have currently is that I have good low end power and good mid range but as I reach top end ( I have no tach) the motor starts to "4 stroke", usually above 30mph. It will hit sometimes and I can feel the power pick up and the exhaust note change. It will keep doing this until I drop the rpm considerably. So, I'm pretty sure I need to open my jag and mess with the jumpers? Any advise or tips?
Thanks, Sean
