I've been given this set up to try on my 02 srx:

About 4,5 Grams in Heel, 6 grams in tip
50/36 or 50/38 helix. I have a hauck red spring set up at 70 deg most of the time. Is this waay to stiff? I like the spring because it keeps some backshift and doesn't slow the sled too much when you hit soft snow on the trail.

The thing is, it overrevs like crazy with 22/38 gearing, way up to 8900 rpm at 8/10th throttle. The primary cover is new (so the bushing is new then), the primary sliders are new so are the secondary ones. I even tried 23/38 gearing and 8 (yes 8!) grams in the tip, with the 50/38 helix and that would only bring the rpms down to about 8500 (I know it is the right rpm for long pulls) but I want to see for once rpms under 8500.

Could it be binding? In that case, where.
 
dont use the red hauck spring in secondery! its very long, and your srx will not perform as well, try green at 80 or silver at 70 degrees.. it will not backshift as well, but its way faster! and i think your rpms will dropp a bit..
 
also to add that hauck red is wound differnt then a regualr yamaha sec. spring. so 70 degrees is differnt then 70 with a yamaha spring.

I would use a green spring at 60-70 and it will run quite a bit better for ya, nothing wrong with your 50/38. Run as much weight as it will pull.
 
hey adrian.....do as I did,take them HC's off and go back to 8Dn-20's.I have mine sitting on the shelf as I cannot get top end with them.They are best suited for 1/4 mile drags but not long haul for top speed.
 
with all the changes I made to the HC's with weight,couldn't get to much past 100 mph.Went back to the 8Dn-20's and instantly was near 115 mph..and that was with a worn out clutch.Now that my clutches are totally re-built..should bury the needle.4.5 inner and 5 to 5.5 outer rivets did it for me.Once I get a good hard packed surface to try on and a long stretch..will let you know the exact comb's.Your 1.25 track will slow you down some I think to,but I think you dropped 1 tooth upper sprocket didn't you to compensate for the track.
 
Thanks for the input guys: The reason that I used the red hauck spring (that was in fact would up right) was that it would keep the motor from overloading thus triggering the dcs light. Yes I know it might be chasing my own tale when trying to reach top speed like this. I will for sure try the green spring again.

Henriette (bluemonster1), I was just wondering what was wrong with the HC set up in the srx. Right now I have a really expensive hauck #5 kit in that sled. We'll see how it performs. Oh btw, the heelclikers are NOT for sale, they are being used in my 2001 MM.

nice to hear from you again Adrian!!!!LOL I may set up my HC's later in the season once I get my current setup spot on and see what happens.I have a spare clutch I can install them onto and it would be a simple switch of the clutch and helix to 50/38.Once there is a good packed surface to test on,right now it will not be worth trying to test out the HC's.
 
But I have a question, howcome my srx pulls 8 grams while the others pull 6?
A 2 gram difference should bring the rpms down by at least 200 rmps right?
Is the tight spring responsible for all of this?
 
I know that henriette. It's not like I tried the exact set up from the MM on the SRX, LOL.
 
The Hauck Red is wound differently than the yamaha red. It's doubled, So If you want 60* wrap, Put the Hauck red at 120*. Install it at 120* and tell me what the RPM does. That Secondary is only wrapped at 35*.
 
norwegian, do you have a 50/40 helix to try? another reason for the higher rpms on top, is because of your shallow finish angle on the helix. if you had something a little steeper like the 40deg finsih vs the 36, it would help pull the rpms down on top. if you can add 2g or so, and not see a change, then there is no "balance" between the 2 clutches. if you have a 50/40 helix, try that and leave the weight alone for now.

I have it wrapped right: I got the instructions from a Yamaha dealer. As stated in an earlier post:
"Thanks for the input guys: The reason that I used the red hauck spring (that was in fact would up right)".....

However, I am curious how you can get a 35 degree wrap???

Henriette: You know, always funny. And this message is only for YOU. HEENriette :P

You said you have it wrapped at 70*. Hauck's ACTUAL wrap would be half of that (35*). ACTUAL meaning in comparison to a typical yamaha wrap.

Sorry, I meant Haucks actual wrap at 70 deg.

No, I don't have a 50/40 now but might consider bying one later.

Maybe this could be your problem?
