Geez that seems high, is this accelearation rpm or full shift on on hardpack. I would recommend if you are gonna spring for some weights (probably 65-66g) you mays well just get a kit and have everything, depending on your riding style and conditions you most often ride in.

This was on max recall on a 3/4 mile run.....it was on a plowed road
so the condition were right for speed,,it showed 117 on the speddo
it was vary light going packed with about 1 cm on top
not much to slow her down..the other time i checked was a accerlation run
let of her about 150 feet ..it was just around the yard.
Any other suggestion's??

117 on the speedo? That's incredible-I don't think I would change a thing. That's damn near top theoretical speed on the FCat. I got 109 on the lake yesterday-3/4 mile and max recall was 8000 RPM.

I would not use max recall to calibrate. It could be a point where it lost traction or spiked, I have seen the max recall not be real indicative of shift out rpm. Switch tach to digital and watch where it runs.

The best, and kinda expensive way to tune, would be to use a computerized needle tach which can replay your run in slow motion.

It was not due to a traction proplem...i have 153..1.175 fast trac installed
and u are propley right to say not to tune by max recall also
gls has said in order to reach top speed on these u might
have to over rev slightly like mine is 8150-8200
but i would rather be safe and let her run in the 7950-8000
anymore suggestion's about weight's or spring's
to bring her down where i want it and not lose power
95% of my driving is done on trail's.Later

Try moving your secondary spring one or two notches LOOSER. This should take the rpm down at least on low end and mid range. You should be able to watch the RPM's climb from about 2-300 RPM's below full shift to full shift while you are holding it WOT. What you are doing is allowing your clutches to shift easier (faster) which loads the motor up a bit more.
