more rpm out of 2010 M8

[Canuk]

I have stock 68g weights in the primary. how many rpm can I expect to gain by going to 66g? (aprox 6-7000 feet).

or,

how many grams need I lose off my weights to gain 200 rpm at 6000-7000 ft.

thanks,

rule of thumb for tuning a clutch is 1 gram will give you 100rpm. so if you go to 66g's from 68g's you will gain 200rpm. Hope this helps.

Not stock, have a new primary spring. Running at 8040-8090rpm.

a spring with a 340 finish should help. slp blue pink 140/340 or the speedwerx red white i think. 125/340.
