MY FRIEND HAS A 450R WITH A HMF PIPE, HRC KIT, JET KIT, AND INTAKE. I HAVE A RAPTOR 660 WITH A YOSHIMURA EXHAUST,JETS, AND INTAKE. I ALSO HAVE TIRES. I WAS CONSIDERING A HOT CAM STAGE 1 OR 2 NOT SURE AND A NEW PISTON NOT SURE ON THE BRAND IF YOU RUN A GOOD COMBO TELL ME PLEASE AND INCLUD THE PRICES PLEASE. I HOPE TO GET ENOUGH POWER TO PUT A FEW LENGTHS ON HIM IN A DRAG RACE.

 

buy a stage 1 hotcam for $130on shipped ebay and buy a high compression piston on ebay, check their prices. you wont be eating dust after those mods

 

i would also recommend a port and polish
