Hey Guys I was just wondering if anyone tried to back the engine so that the belt can get to the top of the primary clutch? The reason why I am saying that is because I took the springs out of the primary and secondary and closed primary fully and opened up the secondary fully and what i found was that the belt was to tight to make it up the primary clutch. So what I decide to try is backing up the engine. The other question is if anyone made an adjustable torque arm to shorten up the arm? Any info would be great.

The question is why would you want to? The more overdrive you pull (past 1:1), the more efficiency you lose.
What I was thinking is to gear down to a 23-40 and the overdrive would make up the difference
Hey Valin I saw your sled last year at the radar runs thats a good looking sled. I was there with Paul Walker, I ran mine and only got 107.9 but it was +10 degrees. I was disapointed.

Doing such a thing is not bad for a trail setup, but, after you move past 1:1, you are losing efficiency, and therefore would not be making as much power to the ground. Sure, you'll accelerate harder due to the lower gearing, but will not have the potential to pull as much top end speed, providing your chassis is dialed in enough to allow this in the first place.
