hi i just got a bender racing roller rooster it came with a 43/39 and 49/43 helix and a all white with blue spring im not sure of the rate of this spring but the guy i brought it from said he had the twist at 30, i have a 94 vmax 600 with reeds, psi twin pipes and thin headgasket, what do you guys think i should run for set up, i do alot or ditch banging and a little bit of jumping.

won't work on a '94 vmx600. the jackshaft was changed in '95 to acccomadate the new reverse cam secondary, which is what the roller rooster is based on.

its got a newer shaft its already on.
helix,s are too steep for your sled. 43/39 might maybe work with a lot of messing with the primary. run silver yamaha secondary spring at 60. I hope you know how to tune clutching. It,s gonna take a lot of playing around & even then it,s to steep for what you want to do.
You should have checked with those that know before you bought it.

its seems to work good with the 43/39 with a bender blue spring at 30. and why would it be to steep if the stock one was 41.
43/39 is the same as a 53/49 of anyone elses billet helix. Add 10 degrees to each end to compare a regular helix. this is a very aggressive roller & imo the best one I have tested.I used 43/39 in a 250 hp turbo rx-1. Anyway; knock your self out. Your betteroff with a helix like a 41/35 or even lower. I am just trying to offer my 7 years experience using that exact roller.

the wh/blue spring is why it's working w/ the 43/39 helix. that is a very aggressive spring. you could actually run it @ 20* which would reduce full shift rpm's.

try finding a 39/33 helix. it should fit the bill a little better. using one on a '98 600 xtc and a sx viper that's piped/ported.
