little clutch help please??? lost rpm on new setup

[teamtampico]

Last year I ran a 151"x 16" geared 19 38, team clutch took the red black out and put in soild black. 70-48-36 primary is a black with green stripe, with 64 gram weights, sled ram 8100 rpm.

This year I put a 162" 2-1/2 15" geared 19 42 same clutch set up! sled only runs 7500 rpm. I put a almond spring in the primary that helped the engagment. next I put the Helix in the 66-44-46 seld ran 7700 in powder next put in 62 gram weights sled still runs 7500-7700 on a load but on the hard trail pulls 8500+rpm

Anyone got a idea on how to get this thing back to a steady 8100 on trail or climbing the hills??? Whith out going back to last years setup!

clutching issues

I would tighten up my secondary spring a notch and see if that would hold it up a little. You are pulling alot more track and maybe this will help you maintain the rpms.

Alot of helix for that track IMO. What sled is it on? What elevation?

I'm having the same problem on my 900. I've tried lots of different spring and weight combo's. I now think that I might be geared too low so my clutches are in overdrive and can't backshift. I'm running 19/43 and might try 19/40

Making that big a gear change is more than likely what wiped out your RPM's. A small gear change (1-tooth) will make your backshift suffer and can drop your RPM's a couple hundred. You may have to lighten up your primary a couple grams and run a few less degrees on your secondary with a stiffer spring. What your explaining is very common with that big of a gear change. Your secondary isn't feeling any load against the ramps and is simply upshifting like it should.

Helix is too big.

that gearing sounds pretty high to me unless you got a good runnin 900 or bigger. 2.5 is a lot of paddle.

Gearing

I would try a 20/42 or 21/42 gear set up and go back to your last years clutch settings before messin with more helixs or springs to get more rpm it has to be done in the primary clutch along with gearing ..

you need more backshift, get a stiffer secondary spring.

you need more backshift, get a stiffer secondary spring.

I'd try that first. I just put tractor gears in mine(19/47 and 7 tooth 3" drivers) and I have the same problem, went from 8200 to 7400, gonna try that too and see!

here is a base line mine is an 03 edge 800 with a 159'', sinlge slp pipe, fresh air kit, the lighter VES springs, and reeds, i run 64g polaris weights,team orange primary spring, stock secondary spring and helix, geared at 19/42and it turn right at 7800 rpm. Sound correct?

I would go to a 54/38 or 54/40 helix.
