SO i finally won a crankcase on ebay. I can start putting the blaster back together. I was wondering if anyone has ever heard of this YAMAHA BLASTER NAMURA HIGH PERFORMANCE PISTON KIT. NAMURA TECHNOLOGIES INC. PISTONS ARE THE PISTONS WITH AN ATTITUDE. THIS PISTON KIT WILL ADD A TRUE 5 HP TO YOUR BLASTER THAT YOU CAN FEEL FROM RIGHT OFF THE BOTTOM, AND PULL A STRONG 300+ RPM (PIPE LIMITED)! THE PISTON IS THE TRICK. THE PISTON ON THE EXHAUST SIDE HAS A NOTCH THE WIDTH OF THE EXHAUST PORT OF 1.7 MM DEEP, INCREASING THE EXHAUST TIMING BY 3.5 DEGREES, SEE PICTURE. ON THE INTAKE SIDE OF THE PISTON, THE INTAKE HOLES HAVE BEEN ENLARGED CONSIDERABLE, AND RAISED HIGHER IN THE PISTON SKIRT TO INCREAE INTAKE TIMING AS WELL AS THE NOTCHES ON THE BOTTOM OF THE PISTON SKIRT HAVE BEEN ENLARGED FOR AN IMPROVED DEEP BREATHING INTAKE CAPACITY, SEE PICTURE OF STOCK PISTON VS. HIGH PERFORMANCE NAMURA PISTON. GREATLY IMPROVED BREATHING CAPACITY, AS WELL AS EARLIER INTAKE TIMING. THE COMPRESSION HAS BEEN SLIGHTLY RAISED WITH A DUAL ANGLE CROWN TO COMPENSATE FOR THE INCREASE IN INTAKE TIMING, THAT NORMALLY LOWERS THE COMPRESSION SLIGHTLY AT LOW RPM'S. THE PISTON ALSO HAS MOLYBDENLUM COATED SKIRTS, FOR GREATLY IMPROVED ANTI-FRICTION THAT IMPROVES HORSE POWER AS WELL AS PISTON LIFE. THIS PISTON ALSO FEATURES AN ANODIZED ELECTRA-COATED PISTON CROWN TO DISPENSATE HEAT INTO THE HEAD FOR BETTER COOLING. THIS MAKES FOR A STRONGER RUNNING ENGINE THAT RESISTS POWER FADE UNDER EXTREME RACING CONDITIONS. THE ALUMINUM CONTENT OF THESE PISTONS FEATURES A SUPER HIGH SILICONE CONTENT FOR ADDED STRENGTH, AND ADDED LUBRICITY. I HAVE RAN USED THESE PISTONS FOR ABOUT 5 YEARS NOW, IN ALL KINDS OF CONDITIONS INCLUDING BUILT UP RACING 2 AND 4 STROKE ENGINES TRYING TO BREAK THEM AND HAVE FOUND THEM TO BE AWESOME PISTONS IN DURABILITY, PERFORMANCE, AND LONG ENGINE LIFE!

I dont know if i should get it or not. I also found out i have a mikuni carb. What else should i do?
