anyone used a power pump?

Yea i realized that after i read the whole description...they have a bunch of parts that are not for blasters lol
 
some people say they work but I don't know. Some of the engine builders here will tell you they don't really do anything for a single cylinder either but i know the yz80's had them so you would think yamaha would of tested and made sure the boost bottle did something before they put them into production. Boost bottles help to equal the pressure for twin cylinders though and you notice the difference there just not for a single cylinder. Only way to find out what it does is run a dyno but i have never seen dyno charts for boost bottles on a blaster.
 
i think that might be for a blaster but i dont know where it would go my brothers kx 250 has one on the side of the motor but a blaster has nothing like it that i know of
