Modifying Jets in GZ Carburetor

[catchemall]

Just installed a 16 tooth drive sprocket today; sure does improve the drivability in the first 4 gears; haven't had a chance to stretch it out in 5th but I can tell it is going to be a load on the engine.

There is a kit listed on E-Bay from "6 Sigma Racing"; which modifies all of the jets in the carb; rather than just the High Speed jet.

Has anybody out there installed one of these kits or have any knowledge of how they perform.

I have not made any changes to the intake or exhaust; yet.

Thought I would try this kit first and see how much improvement it makes if any before modding the exhaust or intake.

The ask for specifics on mods made; altitude at which bike will be operated, etc. Seems to be an engineered kit from the description.

Would be interested in any information anyone can provide.

Thanks,

Jim
