Just got this sled, put new top end on it and think it's running to many rpms, saw 9000 today, should shift at 85 or 8700rpm. Clutched for over five thousand feet per ac right now, has anyone tried throwing more weight at the primary or different helix angles or springs in the secondary. It will probably spend most of it's life between two and four thousand feet from now on. What worked best on these sleds? Any thoughts welcome.
Thanks.
Thanks.
