I just got back my parts I sent to fast frank racing and I was pretty blow away by the work he did. Especially on the gears. On the big primary he faced both side before machining the holes rather than just punchin some holes in it. Top notch work.


Large primary
Before 4lbs 10.6oz
After 3lbs 11.3oz

Small primary
Before 2lbs 5.7oz
After 2lbs 1.5oz









Clutch case cover
Before 4lbs 1oz
After 3lbs 8.6oz

At what point does lightening the gears become a bad thing? Although they look super nice, I'm afraid to do similar due to weakening the gear itself.

Ohhh it likely going to rev like crazy. I know that. Well on all the newer sbk's and 1100s/evo's the internal gears a being cut and lightened from the factory. Even some of the older corse racing stuff was too.

You would have to remove a lot of metal before it compromises the gear.  I've seen lightened gears with what looks like 75% of the metal removed. 

The main issue is balance.  As long as the gear has enough metal to keep the toothed portion attached at speed and it's balanced, not much happens.

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the air—these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

These cut-outs on the clutch case cover were common on the race bikes from the decade-of-dominance era.

Sorry for the interruption, just curious about something..

with a set of custom manifolds, or possibly a modified  set of 900 manifolds, could the FCR's on a rail be used for this project with similar success ya think?

You wouldn't want to, that'd be going to a long-manifold: no good for big power.
