First make sure your secondary clutch is fully shut and the belts not sucked down in it, if it's ok check the center 2 center distance between the clutchs, should be 11 1/2", if thats ok you'll need to adjust the secondary sheaves.

the easiest and most accurate way to make sure your belt is ridng where it should in the secondary is to have the sled on a stand, start the engine ,spin the track by use of the throttle and let it slowly spin down to a stop. DO NOT USE THE BRAKES!!!

then shut it off and measure deflection. I like to see at least 1/8 inch of the belt over the sheaves

I make sure the belt is out all the way in the driven and set it as tight as I can set it with the sled moving forward when the clutch is disengaged.

That is usually about 1 inch of deflection.

When you start the sled on a stand warm it up,give it a few burst of throttle.let it idle down and when it does,the track should want to move ahead a little while sitting on the stand.(not on the ground)

Exactly.
The track needs to spin slow. If it spins fast the deflection is too tight.
