    Hello,
    So we own a 2012 venture GT, We purchased the sled with 300 miles on it and I noticed the spare belt was gone when purchased. The guy we bought it from played dumb. Long story short 1100 miles now and burned 3 belts. when driven under a normal load this thing will over heat belts in a hurry, It will delaminate the top of the belt and have the swirl marks on the side. Just by eyeball the alignment looks good, Ive messed with belt deflection and it seems to make little to no difference on belt life. Ive inspected the primary and secondary clutch for anomalies and find none. I did replace the primary spring with a "soft start spring" and this had no affect on belt life. I also tightened the secondary spring up by one number with no improvement.

    Looking for a little help, What is the center to center suppose to be on the sheaves? Is there a red neck alignment bar or way to check this other then eyeball? Can someone please explain the adjustments on secondary ( 1234 and the ABC)? Id really like to increase clamping pressure but am not complety sure on what setting to try. is this a common issue with these sleds? Any and all info will be greatly appreciated..

    brother had the same issue on his 2013 rs venture gt. we ended up clutching the sled for more snap/low end belt grip and it has been good so far. they clutch them very soft for comfort from the factory and odds are the belt just slipped itself to death in the primary. need to replace the weights in his as we got someones drag race weights and it is causing issues on decel if you do not pay attention to it. i hate a sled that when you punch it, it makes noise only and nothing happens.

    Couldn't a guy continue to tighten secondary spring to achieve more clamping pressure?

    no as the belt is slipping in the primary. how are the clutch temps while riding? bet the primary is smoking hot.
