Guys, I had great luck with my Heavy Hitters and O/S/O spring in the primary on my RX-1 Mountain. I used a Dalton 54/42 helix with a silver spring in the secondary. This setup pulled very hard and was great for drag racing but for hill climbing my upper RPM would drop from the 10,500 I was seeing on the trails to maybe 9,500. This was killing me in the steep and deep.
So in an effort to deal with this problem I bought a shockwave adjustable helix. It seems to be working pretty well for me. I am now climbing at 10,250 on my way to 10,500 and it makes a huge difference in the ability of the sled.
To do so though, I have had to drop the weight of my heavy hitters to be able to pull the 10,500 RPMs I am looking for at altitude. I am using the same springs in the primary and secondary as before the shockwave. My primary weights have dropped dramatically. Where I used to load the engine through heavy primary weights and and a fairly agressive helix I now am trying to load the motor through a step helix angle alone (and light primary weights).
My question is: Can an engine be loaded effectively through the secondary via an initial steep helix angle?
Yes, I can feel the motor pulling harder when the shockwave adjsutable ring is moved out counter clockwise from its seated position. As the ring is moved out from the seated position the ramp angle of the helix gets much steeper and loads the motor but I can't tell if it loads the motor as hard as heavy primary weights in addition to the steep helix angle. I suspect not.
Can someone please help shed some much needed light on the subject?
Thanks

Would like to know answers to same ?'s Looking at getting the shockwave but how do you get it to work the best on a RX MTN?
ECP kit and single glasspack exhaust.

You can load the secondary but your risking belt slippage & poor backshift which is a killer in the mountains. Your way better off in mountain riding to load the primary & then keep the secondary shallower to help grip the belt harder & backshift while climbing in deep snow.
