NC35 Lightweight Flywheel...or Crank?

[RoninZX-10R]

I currently have a GSXR flywheel and generator installed on my NC30 which is absolutely brilliant (highly recommended to anyone thinking about it), now my issue is with my NC35 (both racebikes...too many toys according to the girlfriend ). I love the bike, has more torque to punch out of the corners compared to the NC30, however due to the heavier flywheel (or crank?) it doesn't rev as quickly.

My question is what can I do, machine the flywheel to drop a bit of weight, or would the crank have to be lightened (not really what I want to do). Also, would lightening the reciprocating mass have any adverse effect on the driveability of the bike?

Thanks in advance

Why not just remove the flywheel? Being racebikes why would you need it.

Most race regs in Oz require the bike to have a working charging system.

This year I'm running in the Formula 400 standard class which requires a working charging system, but next year I'm thinking about going into the modified class, so I'll be able to do whatever I wish.

Wasn't sure whether removing the flywheel completely would ruin the driveability of the bike, way too much engine braking and hard to get off the line quickly.

Has anyone had any experience with machining the flywheel? And if so, how much matrial was removed, ie how many mm removed from outer surface?

That's what I've heard.

There are pros and cons to reducing the engine inertia, each to their own.

I'm no racer but I've run a 35 with no flywheel and didn't notice any side effects

I ran my NC30 race bike total loss and it was awesome. Madeit so much faster and did not affect my engine braking so much that I noticed (though I always ran a high idle before I removed it)

I have lightened NC35 flywheels, typically losing 25% of their weight. This leaves them with enough material left to enable balancing and the electrical system to continue to function normally. If you need to know more pm me.

why not just do the gsxr mod on the 35 too?

Out of interest, what is the cost of a GSXR genny setup + adpator?
