stock 400 will beat a stock blaster and will need more like a big bore kit too beat him . dirt wheels did this test years ago and said a blaster with a 240 piped and jetted will whoop a 400ex and keep up with the z400. also dirt wheels has since change there mind about the raptor 250 and the blaster.

 

blaster. period. no matter what any honda or 4 stroke fan says, the blaster will take it.
