Thats pretty sweet, is 15f 38r the stock sprocket sizes on the EX?

 

Yep, that's the stock gearing. I think it's geared a little high for the dunes though. I'm going to check out what putting a 14 tooth front sprocket on will do to my top speed....hopefully not too much.

 

Can a 250ex beat a blaster

 

No, the Blaster will eat the 250EX. It's to mild manered to compete with the little light weight 2 stroke.

 

i have a '02 250ex with a t-4 pipe, k&n filter and jet kit and i whooped my friends blaster........but his blaster is stock so i dont know

 

I bet i can beat a blaster with my stock 250ex.Im really light so my 250ex goes prety fast.What is the best pipe for a 250ex?

 

i would say the best pipe for the 250ex would probly be the pro circuit t-4 or the fmf megamax2

 

I was thinking the fmf maegamax2 also.Any one now how much speed it will add on.
And where can i get a grapic kit for my 250ex
