I have a 91 250X with a DG pipe and a K&N air filter on it. If I put a web cam and a set of weisco pistons on it,how much faster will this make my machine? Does anybody else have any other suggestions to make it run faster.
Thanks for any help!

 

Come on guys somebody has to know something which would increase the speed on this machine.

 

It probably won't go that much faster with mods. You need to get a 14 tooth front sprocket. But you have to either shave the case saver or remove it. That will pick up your top-end 5-10 mph.

 

Well how much faster do you want and where do you want the increase power low end or top end let me know and I'll tell ya.I also have a 250x.

 

I would like more power in the low end, but I would like to still be able to keep up with a Warrior!

 

If I drill holes in my airbox and change the jets how much more HP will this give me? What is a good jet size to put on and does anybody know how much horsepower this machine really has!
