« on: September 28, 2015, 09:48:58 pm »
Hi, i have a Zforce 800 53" 2015.

Might not see it but belt wear and stretch does this as well as roller wear.

Check your air filter. The stock ones arent the best and they clog up quick.

All belts will sterach a little. If you were asking about rollers and adjusting the secondary spring, there is info here on that. As far as the wet clutch, I don't think dr pulleys fits the HL clutch you have.

Thanks, i Will try a new belt.
Also, i want to make the motor run higher during accélération to have better power .
The clutching seem very off to what it should be.
I want the engine at 6500 rpm during acceleration all the time. Not starting to accelerate at 4500 and climbing slowly to 6500.
On my sled, when i hammer it the engine stay at 8000 rpm all the Time .

I sure hope you arent comparing a 2 stroke snowmobile to a 4 stroke utv... because their power curves are VERY different.

I know that, but the performance will be a lot better if the engine stay in is peak performance.
Two stroke or four stroke have nothing to do with that. Try a wildcat trail or a 4 stroke Yamaha sled and you Will understand what i try to have for clutching

Our clutching are good for casual Trail ridind but for performance the backshift is way to slow (not good for iniate a drift) and the engine run to low in rpm in acceleration.

If you are running stock size tires and not real high alt. try 24g rollers/sliders to move the RPMs up and moving the secondary from B1 to A1 for a little move backshift. This should help a bit. If you want more stall than you will have to monkey with the wet clutch and right now there is not a lot of info to go on.

I've been playing with settings myself and here are 5400 feet I run all the way up to 12000 feet with 27" tires. I started with the B2 setting and 22 gram sliders and it did lock in at between 64 and 6600 rpm on backshift but I though that went over the torque curve a bit far so I went down a notch to C1 with the same sliders. Now it backshifts to 56-5800 and holds there until full shiftout. Then the RPMs go up to the limiter. For my needs, this works well and its a killer on the trail. Almost no need for low range anymore. Here's a quick vid from today.
