250x sprokets

[Krazy Kid]

If i run a 15 tooth rear sproket and a 32 tooth rear on a 250x will it really run from 65-70? If i do this will i sacrifice my bottom end? Could a pipe give me ne more bottom end power? thanx :D :D :D

well first of all with my experiences with my friends 250x a 14 would barely fit and and 15 might not even go. there is a certain # on back to where u have to get a new sprocket holder. u will loose alot of low end unless u are modded up alot. i would keep my low end if i were you. and the right pipe will give more gains. a full pipe on 250x 300 ex helps cuz the stock one is soo restrictive. im only sayin this cuz i put a 16 on mine and ordered a 36 and i took em all off and put stock gears back in . cuz its no fun wit out the low end. my friend wit his had a 14t and thats it wit 22 inch tires. and he can keep up wit me untill i nail on it. but thats jus my opinion

i don't think a 15t will fit on the 250. I have a 14t on my 300 and i had to take off the case saver just to get on. Also, a pipe won't do enough to gain back all of the low end you will loose. Your best bet would be to get like a 14-36 and put a cam and piston and more if you want. Then it will hang with a stock 400 pretty good, or at least mine did when that's all i had done to it.

K i think that i will go with the 14 36, but what kind of piston and cam should i get?

Its possible, you have to take the case saver off though.

I dunno if im gonna get a 15t sprocket, maybe a 14, cause 15 wouldnt be any fun for trails...

but yeah, with that gearing and a 15t front sprocket, you could hit 65, probably more.


I'd get a WB E-series pipe, a webcam( a good one), and a reputable piston thats atleast a 10:1 compression.
Thats jsut me though, you can do whatever ya want.
