Machining stock flywheel

[pcv57]

If you're in the US, European Cycle Services does a great job machining down your stock flywheel. They're in Middletown, NY. I had that done and put a 14 tooth front sprocket and I noticed a lot more chugging at low rpms. It definately spools up faster and I have noticed a diffrence in engine braking, although not too much. I did scare myself when I was rolling along in 1st gear and hit the throttle. The front wheel stood right up

Actually i hav the electrean quick throttle cam

Have you used the lightened flywheels on the smaller motor.  i only ever here about large case motors with them

world of difference on the 620 since the throttle has "dead spots" and is such a long pull.  helps eliminate arm pump esp with the quick cam.
