OK, I have a '01 SRX 700, it has 144 studs, bender can and long traveled rear suspension. The rest of the sled is stock.
I need some clutching advice to help me beat my friends ski-doos ( I am the only Yamaha )
I do most of my riding on groomed trails and somtimes some powder cutting trails through fields.
I was thinking of:
stock weights with 4.5 in both holes
w-w-w primary spring
either the red secoundary spring @80deg or the green one @ 60deg
and I am not sure on what helix to use. I can get a 54/42 or a 48/40. Would either of these work well or what else should i use?
I was all so thinking of droping down a tooth or 2 on the top gear. How much top end will i be losing ??

load the stock weights, stock primary spring, green secondary with the 54/42 should be close. Run it at 8450 rpm
With that 54-42 you may have to wrap the green spring to 70.

Should i go with another helix?
What about gearing? What kind of effects will that have on the clutches?

That helix will work fine, nothing wrong with a 70* wrap. I wouldn't gear down more than one tooth on top unless you are really heavy and ride tight a$$ trails, or unless you are dragging short distances.

ok i'll hold off on the gear change
thanks for your inputs guys

48/40 Advant-Edge helix
leave the gears alone
I had this setup from "Turk" in my 01 SRX and it went like a raped ape!

Hey Vice did you lose any top end?
I am mostly looking for harder accerleration. That set up from Turk is about what i want to do. I was a little concerned about the helix though.

I gained top end and acceleration because it kept my motor at the proper RPMs better than the stock set-up. It's a great over all setup that ran better than stock in any situation I used it in.
As for the helix - keep in mind that a 48-40 Advant-Edge helix is a differnt cut then other brands. It's much more aggressive then the numbers indicate.

vice what helix are you using exactly is it the roller one or the nickle plated helix? What is so different with advant's helixs?

advant-edge helices are just cut more aggressively than their numbers indicate, gotta add about 4-5 degrees to initial and 2-3 to final to get the equivalent of other manufacturers.
