what kinds of after market products are available for a 250ex to increase it's speed/power?

 

K&N makes a high flow air filter for the 250ex they also make a jetkit for the carburetor. Big gun has a exhaust system out and so does yoshimura. Thats all I know of right know.

im not sure but if i ways you i would get the yoshimura pipe thye are a big power gain i here you'll need as much as you can get with a 250ex for it to be a faster.
