    Polaris snowmobile exhaust valves on pro 785

    I know you can use Polaris snowmobile valves on a 785 motor, with the adapter. Anyone know the snowmobile application for the valves ? After research came up with 2003 Pro x model.

    Not sure what adapter you speak of?

    We had sled valves converted by welding the 785 bases to it. Then had a groove machined into the valve for the gas

    It seems like there are only 2 styles to choose from. Either of which can work. However, the ones with the blue cap is the preferred model.

    Like this.

    You should be able to get them for around $30-40 a piece. If you need any 785 exh valve bases let me know.

    On the snowmobile valve setup, from reading earlier posts here, I would assume I would weld or bolt the Pro 785 base to the snowmobile setup, groove the and install the 785 valve ?
