well i have 22 37 right now so i think ill go back to 23 37
run the w/w/w/ primary spring, that will bring down the rpm's. you want 8300 on the 98-99 srx's. Go out and test it before racing it, try to run the secondary as loose as you can, if you have to leave the line by feathering the throttle thats ok in a speed run, you dont want alot of secondary spring tension as it sucks away topend mph.
ill bring my w-w-w this weekend on the lake ill put back my stock gear and ill try both spring with my 8dn-00 will see the difference
