WHAT WEIGHTS DO YOU USE ON YOUR PRIMARY? THIS IS WHAT I HAVE 50 WEIGHTS HPD RED/ YELLOW LOOKING FOR MORE BOTTOM END POWER ? WHAT ABOUT HPD SILVER/GOLD SPRING OR SILVER SPRING?
I HAVE HPD TRAIL MOD WITH RACE MOD PIPE AND 39 PWK AND V-FORCE REEDS THANKS

 

ive got the HPD violet with 10-56 weights. tons of bottom end. but then again, the 400 and 500 are totally different for clutch setup.

right now i am trying the red/yel with s55 and it engages at 3500+ rpm and topping out @6700 rpm and rcr mid pipe and it seems to have good bottom end spins my 25" vampires easy

 

TRy a set of S58 weights and that should get you some bottom end but check to be dure you are getting full shiftout.If not you may have to go with a HPD red or violet.

 

Wow Charly. I didn't know that you ran that setup. I bet that sucker takes off like a rocket with as much torque as those machines have. That's what I run on my machine.

well i am sorry to say that i dont have a tach hooked up yet.

but i have tried several springs and weights and this is by far the best out of the hole, seat of the pants, go get em feel that i have come across.

race mod pipe? try the gold HPD primary or silver or for more
aggressive go for the blue with 55 g of weights.
with the trail mod the pipe won't peak as high it should be,i think
your setup should run around 69-7000 rpm.
