Hi all, I just installed a cvtech clutch on my bike. As per cvtech instructions I installed the 0951-1021 primary spring and 20g weights instead of 18g, because I have 27" mud lite tires (12rear 9front). In high my engagement is perfect at 2250-2300 and shift out on full throttle pull on the road goes up to 7450-7600 then drops to 7250-7300 but the bike won’t climb back past 7600rpm or so and it tops out at 68mph. In low it will go to redline at about 42-44mph.

What can I do to help climb closer to redline? Lighter weights to 18g?

Thanks
