Before i bought my bike it was laid over on the left side damaging the stator and flywheel. The guy who fixed it threw in a high performance stator. Well he didn't seal the cover very well because it had a very slight leak, so I pulled it off to reseal it and found that the flywheel is scuffed.

It's not contacting the stator or anything like that, but I was wondering if it being slightly off balance from the scuffing would affect anything. New flywheels are a bit pricey and the damage isn't very bad, so I was thinking about pulling the flywheel and just taking about a 1/4" off with a lathe. This would get rid of any damage and would put it back in balance (while also shaving a couple grams of weight, resulting in faster revs). Has anyone lightened their flywheel before for strictly performance gains, or would the decrease in inertia hurt the bike more than help.

Any thoughts?

 

Are you feeling any vibrations?

 

no, but I figure even small vibs that i can't feel can be terrible for bearings at 12,000rpms
