Polaris SPORTSMAN 800 engine

in this clip we will show you step by step how to remove old and install fresh pistons in a twin cylinder engine – POLARIS SPORTSMAN 800

Here a little about Namura piston and it’s features: 

MOS2 (Teflon/Molybdenum) Coated Skirts
A rolled-on application process provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction, and helping to eliminate cold seizures.

Machined Smooth Heads – 
Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%.

Anodized Domes – 
Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons.

AC8A Aluminum Alloy – 
Our pistons are made from AC8A aluminum alloy which is ideal for use in performance pistons. Due to its high tensile strength, high wear resistance and low thermal expansion rate at high temperature, AC8A aluminum alloy makes Namura pistons a smart choice for any rider.
