1200R flywheel:lighten & balance
Does anyone on the forum balance and lighten the stock flywheel for a GP1200R? I know George of HPT used to, but I believe he has passed away and I'm not sure the business is still operating. Any help would be appreciated!

Tim Judge did one for me a couple of years ago. I dont know if he is still doing anything on the GPR's except for porting though. THe one he did for me was an OEM non charging though.

I had asked Tim Judge about this a year ago when he did my porting. He told me he did not like to lighten the oem flywheels because they had the tendency to get weak and then crack.
9t8gp1200 I know there were some lightened rad flywheels for sale on the board. May want to do a search for it. I am sure groupk can lighten the oem flywheel up, I'd get them to weld it though. Call Harry up, great guy to deal with.

the rad flywheels are the worst crackers of them all. Avoid like the plague.

Pics of mine, this was done by HPT back in the day. RIP George.

If I am not mistaken the stock ones are around 4 lbs and the lightened ones range from 2 to 2 1/2 lbs.

I can lighten your flywheel the same way George Grabowski did, but it's expensive to do because it has to be mounted on a rotary table using a milling machine to cut the center section between the trigger pickup points.
Most people just lighten them by cutting the front and rear section around the crank pickup area using a lathe.
My normal flywheel lightening price is $60 with free return shipping within the USA, but if you want it done like HTP-Sport did, it will cost $130.
Also, I have some 61X & 62T lightened flywheels in stock for $100 with free shipping in the USA.
