Lightened flywheel


Recommended Posts

A million years ago there was someone here that cut maybe 30% more than other guys from the stock flywheel not just a little off each side of the magnets. 
I’m wondering what everyone suggests for a lightened flywheel.

How much weight do most take off?

I really don’t know?

It helps in “reving” quicker?

What does it do?

I have a lightened flywheel that came with a motor I was told built by hytechracing in Riverside California. Maybe he can shave one for you.

Duncan racing charges 90$ I don’t know how much they take off though.

some old posts on this:

Boonman from 2004 "The flywheel gets chucked up in a lathe and turned down. 8 ounces of weight is removed from the the outer diameter of the wheel. 4.84" is the O.D. of the wheel after machining."

BdBanshee from 2004  "I remove 8-9 ounces from the O.D. of the flywheel. Since all stock flywheels don't weigh the same, the amount varies, but the finished weight is the same.

I built a fixture that the flywheel fits on, I do not clamp on the flywheel.
