I will finish my break in this week. I have not installed the aggressive clutch kit yet. I also got two extra primary springs (hpd plain/hpd brown). Hpd red/yellow came with kit 40/36 helix and violet secondary spring and 10-58 weights. My question is what weights (10-58 or stock) and which helix (40/36 or stock) would work best with the three different primary springs

 

If you dont have a tach to tune with go with what HPD recomends.I went through the same thing with my sons TB and ended up with the parts that came with the pipe and kit.

 

Well I just installed a hpd clutch kit in mine, I called Rick from RCR and he sold me the red with yellow spring and a violet secondary spring with the 10-58 weights. I didin't get the helix with it because Rick said that it really did'nt make that much of a difference in performance. He told me that the springs would do 90% of what a clutch kit does without the helix. I hoped this helps but if not I would give HPD or Rick from RCR a call.....

 

Try the red /yellow with the 58's,then try it with the stock weights.Most people end up with the stock weights (S-55)

 

I'm running a red/yellow with the stock weights (s55) and a violet secondary with the stock helix. Runs great and backshifts like a dream.

 

Thanks Ced, have you tried the plain or brown primary springs ? Duneaholic what was the differance between the 55's and the 58's ?

 

I've pretty much tried them all.But all i do is mainly drag so my clutching is a bit different,and i have the full race mod on alky now.Like Duneaholic said that is a pretty good combo.

 

I always found the 58 weights to be a little much for my liking. If you dont like the real high engagement, then the polaris brown springs with the stock weights works really well. It has a medium engagement and works great. The only place the 40-36 helix would affect is if you hold the throttle wide open for a long period of time. It helps keep the rpms up on the big end.

 

Bubba could you explain what you mean by a little much and thanks for the reply.

 

They call it the aggressive kit because that is what it is. I personally think that the 58 gram weights shift out too fast. The stock weights tend to have a better shift feel. You have to step back and think that Polaris puts the s-55 weights on a lot of the bikes because they work good. You just change the primary spring to suit what riding style you do. But always put the good secondary spring in. If I was going to buy anything, I would buy only springs. Heck, for the money you save on a clutch kit, buy a good secondary spring, then buy a brown and a red/yellow spring for the primary and see which one you like. Your still way below the cost of a whole kit. Experimentation is good learning on these.
