wr400/426f flywheel weight?

1 post in this topic

I have my yz400f that I want to tame down for trail riding. Does anybody know the weight (in ounces) of the WR400/426 flywheel?

I will be adding a 10 or 12 oz weight bolt on and I am trying to decide how much???



1999 yz400f, enzo tune front/rear, e-series, too much hit for the trail...down-right damgerous for this old dude...
