A little update..
Got some parts yesterday!
Mounted the 48/36 dalton helix, green spring at 60 degrees (3+3), 15mm rollers, and red primary spring with 3.3 bolt in the middle and 3.3bolt + 4 washers at the shoulder.. That is a maximum of washers on the 3.3 bolts i think..
(getting 3.9g bolts next week ( i hate slow dealers...) )
Only tried a little outside my house now, and engagement still to high at 4700 (i understand why, dont worry
) and max pull from start gave me 8600 at first, rising to 8700rpm..
Will try it at 70 degrees twist tonight, or maybe even 80.. Too little snow here to test it fully, so we are going up to the snow tonight!
Still wonder if it accepts even more shoulder weight, but since mrviper says so, i shure will try it as soon as the bolts arrive

Tried it at 70 degrees tonight, without any big difference..
When the belt gets warm, my top rpm`s stays put @ 8600.. Havent tried it over 70mph though..

Any other tips how to get the last 400rpms, and lower the engagement at the same time?
Giving the red spring a last chance tonight, with 80 degree twist.. If i put even more weight to the shoulder, logical, the top rpms will still drop even more, not rise..
Strange though.. Everything moves very easy without spring`s in the clutches, so i doubt it`s a mecanichal problem with the clutches..
But it seems to be different to other vipers, if this setup is tried out before..
Dont think its lack of power either.. My buddy sure dosent think so, as i keep up with his 05 900 fusion
And this is with 400rpms to little (10hp if i read slp dynos correct), and perhaps some more to get by tuning clutches..

80 degree twist (6+2), 8600 rpm`s.. Hot belt/clutch in DEEP powder, but otherwise no problem..
4700 engage..
Trying not to be negative, but it aint easy..

mrviper700 said:Its because of the 47 degree helix!!!!!!!!!!!!!!!!!!!!!!, this is too steep of a angle and the engine can not pull the load on topend thus your engine rpm is low on topend. thats why you need a multi angle helix with shallow finish angle!
Plain and simple, get the correct helix!!!
you dont have near enuff heel weight, you need 5-6 washers and the lock washer so your engagement speed is around 4000-4200rpm. You will never, never,never,never get it to run properly with that white spring!
I have given you all the information below in all the other post.
I`m still looking forward to a reply on this problem mrviper700..
No hard feelings, but i`ve used over 200$ on helix, spring and rollers, without any positive results so far..
Only asking for hints on where to begin to solve this problem again..
Thinking of reducing weight from the center bolt, but you told me not to..
your gonna have to start taking off weight from the center bolt then, you must be down on power for it not to pull that. It can be from jetted to rich, to lean or possibly too much load for your motor. So how many washers do you have on the shoulder bolt total? it should be 5-6 with the lock washer, not 4.
remove 1 gram from center bolt and try it.

Perhaps the 1,5" track makes a difference? I belive it`s standard gear ratio..
I use the 3.3grams standard bolts, with 4 flat washers on the shoulder.. Didnt come with any lock washers, so i havent been using other than the flat ones for now..
Spark plugs are chocolate brown, and i kept up with my buddy`s 900 fusion (with a 1.75" track) several times with this setup.. Even kicked his a*s in some of the pulls.. (uphill in a downhill-ski trail) Thinking this must be ok? He sure was impressed, and must say i was too..
