Just a little performance quickie. The one-way clutch and the flywheel are held together by 8 m6-1.0 x16mm allen head bolts. Changing these out with Titanium units will save you upwards of 2 oz of rotating mass....may not seem like much, but try that at 9,000rpm. The m6-1.0x15mm (closest is 1mm shorter) bolts are presently on backorder with Mettec.com....you'd be in line behind me. You'll need the Polaris #PA-46075 flywheel puller, and make the change during an oil change, cause you're gonna have to drain the crankcase of oil....otherwise it'll be on the shop floor. There are also rotating clutch retaining bolts on the other side....haven't gotten to those yet, but I'll post when I do. [img]i/expressions/face-icon-small-happy.gif[/img]

 

i wonder if you can shave some weight off of the flywheel

 

Tapered socket head. If you want, you can wait til I get mine, then I'll do the final clearance checks. As far as milling the flywheel, that will probably surface later, as shops get more mods. I'll also post info on the clutch bolts when I get that side opened up and measured.

 

There are 8 bolts holding the flywheel to the starter ring gear.
