Ok i have an 03 300ex and was looking for some good sites and parts for it. Can anyone help

 

first off get them stock tires off the back. i use razor tires they are a flat tire and will help you on holeshots and still can ride good wheelies. then k@n air filter will give more power .change you head pipe and end pipe at same time go to a bigger main and piolt jet pip kit will tell you what size jets to use. after you get these things take air box lid off if running k@n air filter.then just hold on.good luck

 

i run a White Bros pipe and header,uni airfilter,i cut a hole in the part of the airbox closest to the carb(helps keep it cleaner than at the other end)and jets,as for tires i run 20in Titan Fast Trekkes on back and 21in Fast Trekkers on the front,if your looking for more top end i would not run a small tire like a 20in.the fast trekkers hook up great(better than Razrs or Holeshots but if your racing run Razrs cause Holeshots suck.

 

oh yea and buy from magicracing.com

 

thanks guys
