RPMs a little low

[theewarrior]

sled is stock but i put a 1.5 track on, fairly hard packed when you hit the throttle it goes around 9000 and climbs to 10000. how can I bring the rpms up a little without buying a clutch kit ,I've check clutches,coils plugs

from what other posters have said, you may want to clean your primary real well

Lighten your arm weight in your primary will bring your rpm up.

Add some more preload to the secondary helix twist...another 10 degrees should bring up the rpms across the shift.

install an orange-silver-orange primary spring from yamaha in the primary. do this first before adjusting any weights.
