well i put the orange one and 3 shims in and running the s55 weights and only getting 6500 rpm i need to get another 500rpm any thoughts ???? shave some weight off and lighten the weights?

 

what kind of clutch kit you playing with?

 

no kit all factory clutch just need to get more rpm

 

I have a heel clicker clutch kit in mine. I have tried the orange spring as well, i now have the white 1 in and think ill go back to stock. But the kit came with a yellow spring that I haven't tried due to the engagment would be way high. I belive it is made for racing. Is that something you are looking for?

 

i am looking for the 400 2 stroke i dont want to go with the hpd spring as climbing can get tricky on the steep tight trails i just need to get some more rpm

 

change the weights a little lighter will get you your 500 rpm's not sure how much though
ask rick ritter he would know for sure.
I have a fist full of weights for diff riding mudding ,trail riding ,snow ranging from 46 grams to 56 grams a little much but I like to tweak
