I have a 38 for sale for 250.
Thanks guys, looking for a 36 as the priority. If no luck, I will start looking at the 38's.

What bikes did these come on stock, if any?
late 90s japanese 125s
KDX 200/220s
various years KTM 125/200/250/300
i think newer betas and sherco 125/200s might as well
i used one on my 2007 Husqvarna WR 125 with success, want to experiment on my current TM Racing 125
Won't the significantly longer body create fitment issues? Why not a 36 short body?
Never had an issue before. Prefer screw top for quick needle changes.
Any idea what size came on a 2003 200SX? I have one of those laying around.
You can measure internal diameter on the engine side to confirm. But it might even be a 39mm, I think the SX models had larger carb than the XC models.
i have a 38 screw top
I don't think I have a spare but I mostly find the KX125 versions of them. Had one on my 01 GasGas MC125 (replaced 38mm PWK), put one on my 88 Cagiva WMX 125 (Replaced Dellorto) and putting one on my 94 GasGas EC125 (Dellorto again) project.
It's a great sized carb for a 125. You get so much more out of the bottom/mid (include ease of jetting) that it out ways the gains on top end which aren't much.
YZs came with 35mm mikuni's for a long time which is another great carb for the 125s.
Those 00s Gasgas 125's have great ergonomics and hydro clutch. I remember finding a mint 02 XC for $1200 for my cousin. He loved that bike. Should have kept it.
Agreed, I always wondered what a 36 bored to 37mm would be like.
