I have a 98 mach1 with a 830 big bore crankshop pipes my pirme spring is black (180-410) what diff will it make if I go to a (210-410 red spring) The othe part is the secondary is the tan spring the most i can get is 14 lbs of pressure ?I was told at HRP that i should have around 18-24 lbs.Should i get a new spring or a diff color.With the spring onA6 the sled will not move the clutch just opens all the way up at 2500rpm.The ramps are 286. what is the diff between the 286 and the 287's ???

if you change primary springs it will raise your engagement
hear is a chart for the secondary

A-1 14 LBS B-1 16 LBS C-1 12 LBS
A-2 9 LBS B-2 11 LBS C-2 7 LBS
A-3 4 LBS B-3 6 LBS C-3 2LBS
A-4 28 LBS B-4 30 LBS C-4 26 LBS
A-5 23 LBS B-5 25 LBS C-5 21 LBS
A-6 19 LBS B-6 21 LBS C-6 17 LBS

when you put the helix in a-6 did you twist the clutch to set the poudage did you check how much you have

what kind of rpm's do you run with the 830 big bore kit :devil:
