Ever hear of thses guys?
 

Hpower - Performance & Diagnostic - Motorcycle

I see they have a lightened flywheel listed for $150 on their site, that's A mod I would like to do.

Anyone know of any other place that lightens/balances flywheels? I don't trust any shop out by me to do it

I've heard of Bill Finnegan and in fact emailed him a year or so ago. Seems straight up but pricey. Most of the VTR stuff like pistons and cams are probably long gone. At the time he only had a couple sets of each and Moriwaki stopped producing them. However he may have found more from his sources.

If you search the threads there was guy on here that was doing it for somewhat less money. There is also a thread showing how much needs to come off.
