Look on ebay, I've seen several on there lately. With those mods I'd be looking for a 36 to 38 mm carb.

[albi0609]

ive...been looking for 1 for the last 3weeks and nothing ..ive bid on someon ebay but i alway get outbid at the end ......thanks guys

but i can get brand new mikuni flatside carbs i think 37mm or 40mm for 140$ brand new are those carbs any good?

[matt250r21]

The only Mikuni carb I would go with are the new TMX style. Look on ESR's website to get an idea of what they are.

[zedicus00]

hey i just posted to links an my posts got deleted... do this go to ebay an search for kx carb you want one off of a early 90's 250 dirtbike

[zedicus00]

ebay item 230019809136
and 250021510239

NOTE TO MODS: these aint even my auctions im jus trying to show these guys what to look for.

[zedicus00]

ALSO: other brands of dirtbikes have the same carb, be carefull some are short body an some have lots of electronics on them. these can be made to work on R's but take more work. the early 90's dirtbikes are USUALLY a standard 38 A/S carb.

That's some good info Zedicus. Has anyone tried the new and improved PWM 38mm carb? Any better than a pwk air striker?

[zedicus00]

PWM's r like an updated PJ style carb, the idle an choke are on the same circut. they arent bad but arent any better then pwk's

also if you need a BIG carb ive had luck with snowmobile carbs.

[Aceman]

Oh alright, thanks Zed.

250 ktm also has a 38 a/s fitted to it .

[86250rrider]

unless i am mistaken the 38mma/s is less than $140 new from honda . look up 2000 cr250 and price it. the 199 esr and others charge is for billet jet board and jets along with pressed on adapter. check it out spend you money wisely the a/s works better than the tmx38 i had .

[albi0609]

will a 2001 KTM250SX dirtbike carb work theres 1 going on ebay foy 70$ buy it now lmk
