i would stick w/same helix for now, and just get some 8dn-20's, load em 4.5g each hole, and try red spring @ 70, with yamaha white spring.
Sanka if you go back and read some old posts you'll see the ol tryed and tru set up for any stock SRX is with loaded 8DN-20s and a 54/44 helix, because you may still over rev with the 51/43 because it's not enough helix for a x, rpms will be spot on.Sanka said:What helix should I run
SRX700guy said:with the 8dn-00 fully loaded get a g-w-g primary spring, find a stock 47 helix and put a green secondary spring in wrapped at 70 degrees and it will pull like a freight train and it has great back shift for trail riding.
I tried the 8dn-20 fully loaded with a w-w-w primary spring and a 54/44 helix with a green spring wrapped at 70 and my machine wouldn't run good with it.
