How many grams in your clutch?

[Skidooer]

Mine is stock with 10-64's.

I ride 8,000-9,000ft mostly.

Current RPM's when climbing are around 7,850-8,050.

I am thinking it would be better off with the 10-62's to get a little more RPM's.

What weight, RPM's & Elevation are you running?

What is the target RPM's?

You would do better with the 62's I am using 66's at 1800-2000' and still in breakin mode but it seems to pull up to 8100 on a few full throttle blips that I have done. Still need more snow so I can't give you much more info then that. My Assault that I had last year (2010 with PC-5) would pull 8250-8300 with the same combination so I am hoping for similar results on the pro rmk assault

I am riding at 7-9k ft with 62 gram belly busters and I am seeing 8200, which I believe is the target rpm.

 

[AkLogan]

0-3000 feet running 10-66's and a 64/42/36 helix im seeing 8150. havnt had a really long pull to see what the r's do on the top end but gonna find out tomorrow about that.

62'S MAX AT THAT ELEVATION STOCK.

 

[polaris1]

8000 - 10000 ELEV.
10-62'S
8100-8300 RPM POWDER HILL CLIMB

 

[B2]

8000 - 10000 ELEV.
10-62'S
8100-8300 RPM POWDER HILL CLIMB

8-10,000 feet with 10-60's, and seeing 8200-8300 rpm..have seen 8350-8400 on breif periods so thinking about going back to the 62's

Ditto here.

10-60's at 9-11K. I also ran the MTX 61.5 and had a little over revving (those are 2 grams more than 10 series weights). The over revving wasn't too bad though, in the powder the sled still pullled really well. I'm still experimenting.

 

[AkLogan]

Bug if ur over revving try a steeper initial or a stiffer sprig in the secondary. I was having the same issue with over revving out of the hole then it would stumble to catch back up and bog really hard for a second

 

[Skidooer]

Thanks guys. I thought I needed to go down to the 62's.

Good idea except that my engagement is too high (sucks in the trees). So I'm going to 10-60's (stock) and an almond/red. This will also be higher engagement, but hopefully better shift out. I have to learn the hard way!

Almond/Red is going to be higher engagement than the stock black/green primary spring and will yield less peak RPM..just so you know

 

[AkLogan]

im talking secondary not primary.

 

[Skidooer]

Ride 7,000 - 9,000ft., 10-62's, Rpm = 7,850-8,100. TO LOW

Im going down to 10-60's This should put me at about 8,100-8,300.

What have you guys been doing to get more RPM's?

 

[Norway]

tach?

How accurate are the tachs on these new sleds??

Anyone hook up something or hear from Dynoport/dynotech if they saw any difference when they had them in the dyno?
