Anyone have any feedback on the new reverse angle helix in the 09 summits? Thinking of putting it in my 08 but can't find much info yet
New 09 Helix in 08 XP?
- Thread starter newfsummitx
- Start date
With the 08 ramps it would be junk. The 08 ramps already have no shift on the bottom, with less helix it would be worse...
your a little off the mark...the new helix is a 43/47...2008 helix was a 42...a 43 start has "more upshift" than 42 obviously...and the ramps werent the problem last year...the cam was "most" of the problem...BJ
Big John, I am looking for info as to whether this is a good upgrade. Didn't have too many problems last year other than not keeping the track speed where it should be. No heat or belt issues. B/c of type of riding I do, about 50/50 in mtns and flatland trails (young family wants to ride too) I don't want to go with a full clutch kit? Thoughts
Now I'm going to have to take a look at that secondary out of curiousity. The secondary has ramps and a ramp, I mean helix? Wonder why they did that?
I thought the new helix was a 40/46....my bad....I disagree on the ramps though...The 08 ramps are junk IMO....I have some different ramps for mine this year...guess I'll see if there is an improvement.

we have the 09 set up in our 08 and are headed for the horns at 8 am--i'll let you know---we did the primary and secondary
I went with BJ's 44/33 helix and primary kit on my 08. No issues and it was very competitive..................

Care to elaborate ther Wyoming T/A??? I assume you mean you've put the 43/47 and the 441's into an '08... or is there a spring change too??? Have you changed the spring tower cap as turbo al has suggested???
If you get a chance, please give us as many details as you can.
Thanks
Should replace the Spring Cup Cover when doing the upgrades. I haven't gotten the chance to try the set-up out but I have a coule sleds that are getting the treatment as soon as I get new Secondary bushings. I also have a couple different helix angles to try out. Should be fun.

had all the updates on soring tower--new rollers --441 ramps and 43/47 helix--no spring changes
Reverse cut helix IMO is the wrong way to go. Sounds like they are using is to compensate for the ****ty A$$ ramps that don't provide enough upshift. The drive clutch should be controlling the upshift. Putting in a steeper helix on the top is forcing the primary to upsift. IMO it's going to make the sled very condition and altitude senseative....

8500 feet to 9200 feet and NO RPM change--SOUNDS to me like thr right direction
hmmmmm, T/A, hard to make an accurate claim methinks at this junction of a new season. I gotta think with your ride you just took, that you are on some trails, not much climbing, and minimal load. Gotta agree with Junkie, reverse angle is a copout.

did the exact same ride last year on the 08 and had to change clickers at lower elevation and back at higher elevation to keep the right RPMS--this might not be the answer to all but in my book its a good start-- also when you hit untracked sno the rpms dropped and they dont seel to at all with this set up

going to snow all week in the horns and we can get off roads next weekend--we'll have a better idea if its a real hit or another miss--there 21" on top right now
PS: didnt mean to hyjack this thread but figured it was better to give what info we had here vs starting another---

Hey T/A
are you running the 6-8 head or the 8-10
I ride from 8-10 sometimes take of from 7500 just dont want to have to run any race gas or have det sensor going off.
