I have a 2001 YZ426F I picked up for the right price. I cant find a flywheel weight. Any other suggestions to mellow it out?

I have the same issue and was thinking about getting a G2 throttle kit. They make a throttle cam that has a softer initiation for the first quarter turn or so.

Put a fly wheel weight on mine and a 450 exhaust cam.
Made it more mild mannered.
