    Top end kit

    Well so far so good was kinda iffy at first cause everyone that I seen online was saying bad stuff about them coming apart but when it arrived it looked quality to me and I made sure all my clearances were within specs so everything has been good I've only ran maybe 4 hours so far but plan to put plenty of time and if everything is fine then I'll even write something later on about it thanks good price and good parts

    QUALITY PISTONS

    THIS IS A DECENT PISTON FOR THE PRICE. THIS PISTON MANUFACTURER SUPPLIES PISTONS FOR OFFROAD APPLICATIONS THAT NO ONE ELSE EVEN CONSIDERS MAKING. THAT MAKES NAMURA MY GO TO SUPPLIER FOR ODD AND HARD TO FIND APPLICATIONS. THANKS FOR ASKING, ART.

    Good for the money

    Measured to exact specs. Nice quality for a cheap cast piston. Good gaskets as well. Needle bearing kind of cheap feeling I reused OEM one.

    Great for the price

    Great product I would also recommend replacing the carburetor at the same time and don’t forget the gap on the piston rings
