New to me sled. 2015 with the 2016 front end. Turbo works well with koso gauge kit and rollover valve and a few other goodies.

Having an issue, smoke from the belt in reverse. Even if just moving the sled 10 ft and getting on the throttle, not going slow. I get some smoke from the belt. Ideas?
The sled also hits the rev limiter way to easy, like the belt is slipping or something is not happy. I would expect it to pull harder from the get go, not hit rev limiter and then slowly start to go. Is there a better belt option out there? Helix adjustments? Or just keep putting new belts on?.

Has the stock original skis, what are others running to get a little more flotation? So far it feels more like it tunnels in the powder instead of trying to get on top of it.

So far I am very happy with the sled and its performance and feel, coming off of a Nytro and an Apex.

THank you to everyone for input and your ideas!

I can't answer the first question but I have thr SlyDog attack skis and they help keep it up. Don't notice it diving under the snow. I just too came from a nytro to a Turbo Viper. Best decision I've mad!

I had a buddy that preloaded his secondary backwards acted very similar to your issue. I didn’t think it was possible but he managed to do it. Have you looked at the secondary?
