Going to run some 400ft dirt drags this weekend, and I wanted some opinions on gears springs ect. --- Rite now im running (race mod on gas), purple primary, s58s, violet sec, in 1&1 position, 14-34 gear. 22" holeshots and I weigh 165. The clutuhing feels ok but shud I gear down maybe 13t? Also with the 1&1 do you still prewind 1/3? Thanks in advance for any input. Gotta spank at least a few shees.

If your going to run 400ft, then I wouldnt change the gearing, especially since you only weigh 165. All else seems to look OK to me. You always have to wind the secondary that 1/3 of a turn to get the helix on the correct side of the clutch buttons.

 

44-38 helix,2-1 position,,lauch no more than 4500-4700 rpm,12-34 gearing.

 

You may want to try the S-55 weights also.

 

Thanks fellas. Im gonna take some s55s, and maybe the blue primary. they dont give you but a few practice runs, so ill try the weights first. Ill post some results. Cant wait, my first time runnin with lites. Just hope the wheel dosent fall off my cousins trailer in the Chesapeake bay bridge tunnell.[img]i/expressions/face-icon-small-happy.gif[/img]

 

blue hpd primary with s55 will run just fine,even you'll have some loose rpm on top end tough with the race porting.
