clutch & weights

[dvsjames]

I just picked up a Polini Evolution 107mm 2g 2 clutch. I used to run all 4g weights and top speed was a little over 60mph but i changed them all to 3g Koso weights b/c i was not happy with da low end but top speed is only 55mph now ;no . If i install the clutch will the clutch make a difference for the low end so i can run all 4gs to get top end back?

back to the 4gr or try with the 4.5gr and feel the range of the rpm in the engine and u choice

with the 3gr you only up the rpm

with the 3gr u only up the rpm and not top speed
try again with 4gr or 4.5gr

thanx for the reply i forgot about this thread but i got the clutch put in and ran all 3gs weights and was back up there a little over 60mph with better of the line performance. i think its time for a new belt and weights and tuning though ive havent change both since last August i can only hit 57mph now but still runs good.
