The Patriot 850 motor is a fun package, but there was plenty left on the table.  The stock porting was relatively mild, and there was plenty of room to bore the stock cylinder out.  Bring you sled to life with our 909 cc big bore kit!! 

The combination of the larger bore, improved porting, and head mod produces one awesome kit.  We offer this kit for both low and mountain elevations.  The mountain series version has a higher compression ratio for extra power.  All kits will run on 91 octane premium fuel. 

For best results we run the D&D y pipe, and our Big Bore Pipe mod.  For fueling we can reflash the stock ecu or a powercommander can be used as well.  Most people will choose to run with one of our mufflers, but stock mufflers work as well if you want to look totally stock.

You can expect to see about a 25-28 horsepower gain with this kit with the single pipe, with awesome torque gains and wicked throttle response.   Keep in mind the Mountain Series version will make about 4-5 more horsepower because of the use of the high elevation domes in the billet head which have the correct higher compression.   

If you don't care about looking stock, testing is in the works with the SLP twin pipes as well for the RMK models.  We are expecting to see about a 35-38hp total gain along with the twin pipes. 

If you are looking to build a racing motor, we can do that too.  The 909cc size is intentionally sized to be legal for the 900 class racing rules.  If you want to build a racing package, please call us for details. 

Kit includes: Boring, Porting, Nicasil Plating, Modify Exhaust Valves, Head Mod, Forged Pistons, Rings, Wristpins, and C-Clips.  The awesome Wiseco pistons used are hard coat anodized, and Teflon coated.  Also, Y pipe, Pipe mod, Donut Gasket, Custom Helix, Drive Spring, Driven Spring, Pro-Shift Weights, Power Commander Fuel Controller, Or our Pro-Tune Ecu Reflash. 

Send in your stock cylinders, exhaust valves, stock pipe, and ECU to get this kit done.  We do have some exchange cylinders available as well for quicker turn around times.
