Shaving the flywheel

(1/4) > >>

Arigato:
I'm having some material milled off my flywheel for a little more snap.  I know some are running the pvl ignition, but has anyone else simply milled the stocker?  If so, how did it work.  I'm either going to be real happy or $250 in the hole buying a new one.   :mrgreen:

Arigato,
 I have not shaved the stocker but have done it on other bikes.  I usually decide the OZ I want to remove then calculate the volume of mass to remove (using the density of steel).  Looks like there is enough meat on the stocker to take off a bit.  Have to watch out for the external trigger magnet which will reduce the size of the band that can be lathed away.  Works the same in reverse to add weight by machining a brass band (not the kind you listen to) and shrink fitting it over the flywheel diameter to add weight.  Let us know how you make out. Cam.

I always ran lightened flywheels in my buggies, down around 10lbs. Made them run like the dirt bikes. Problem with lightened flywheels is keeping the engine idling when stopped. (if you want it too)

Arigato,I have a milled stock flywheel and it?s working fine for my use. :evil:
You know it change the 500cc to a nervous 250cc and hard to ride. :wink:
I will never go for PVL for mx or trailriding ,but in sanddunes, yes. :-D

FuriouSly:
Doordie, how much did you take off?  Ounces?  Or a just milled it to overall smaller diameter?  Thanks.  Sly
