    Do you have any mods on it now? Start with a aftermarket pipe, jetting, mabey airbox mods. Then if you want to spend some extra cash, I think there may be some internal engine mods for those. Not sure tho.

    Mine has a super trapp, K&N, Works rear shock, progressive front shocks, 200x front end with disc brake. 350x headlight. I have a 350x carb for it but haaven't swapped it yet. Just re-jetted to a 150 main jet so I could lose the airbox lid and use all 14 plates on my pipe. I bought it already modded.

    You need a 150 main in that thing? My buddy's has the bassani, k$N, 350x carb and a 130 is just right in that.

    i always wanted to bore a 250sx to a 350. i think the sleeve they use on the 250x big bores would work

    I listed it because if he was looking to make a mud machine the big red has a higher geared rear end so he could put larger tires on the SX without straining parts more than they should be.

    there is a considerable difference in altitude. i bought it withthe 140 and the airflow opened up like that to run in kansas. but man im in south louisiana. lots of O2! i had to choke off the air until rejetting. now its fine.
