902 Pro Tuner kit -Adjustable weight kit for 850 Skidoo models with pDrive clutch (clicker type)
48g-55.7g (48g base weight plus hardware)
The 902 Pro Tuner kit is a fully adjustable weight kit for the 850 with pDrive primary clutch.
Most low elevation 129-137” 850 skidoo models have 49g stock weights. This set of weights is designed for use with the stock clicker assembly. The stock pivot bolt can be used or there are other optional ones from BRP or aftermarket to allow for even further flexibility.
The flyweight top profile is similar to the stock BRP #968 ramp curve on these models.
There are two threaded holes available to allow the position of mass to be placed in the inbound or tip position. There are many combinations of added fasteners that will allow the fine adjustment of “total grams”, as well as the different “placement locations”.
Many combinations of less than one gram increments can be done in different configurations of weight placement on the flyweight.
The threaded holes all have a bottom, so that even the set screw type fasteners bottom out secure. Everything needed for the included gram increments listed is in the package.
The weight adjustment is done from the side of the flyweight. Many racers love the Dalton “Quick Adjust” type of weights like we have always used in the Arctic, Polaris models (and now on the 900 ACE turbo). However, for this application, this configuration was more control of weight placement to suit the application.
As the name suggests, this Pro Tuner Kit was designed to help satisfy requests from clutch kit companies, pro racers, and performance shops who want to tune their own clutching to suit their own needs and/or performance levels.
