About the acc. pump mod, Seems it will disable any squirt at 1/2 and up throttle, hence the larger main? Is the needle going richer or leaner? I read it to be leaner. I may be wrong. Fuel screw should be 1 1/2 to 2 out? Any other tips? I ride tracks at about 1000 to 1800 ft elev. Temp is about 70-90 now. Bike is a '00 with a Pro-Meg (open) and an 8oz flywheel weight (for the occasional trail ride).
