Re: up graded cdi
The thing JAG does is that , with the timing being retarded is that the engine a he!! of a lot LESS vibration. This means LESS STRESS on the bearing and in return your engine will last LONGER , run SMOOTHER and you'll get just a little better gas mileage. I have run the same testing as WB and my results were the same pretty much. I run with jumper A-1 in (24 degrees BTDC), and no B jumper at all.
I have built the Modified CDI & CR-80 coil set-up and had good results as well. They not over priced and I can say this because I know first hand. I've built them & run them . Two things I will not do, go back to stock CDI and never run any less than a DAX balanced bottom end.
