ok i tried looking on sudco website for mikuni parts i need and its a nightmare. did the '02-'03 carbs use the same jets and needle as the '04-'07 ? anyone know anything bout these stupid carbs, im totally lost because it seems mikuni had 10000 versions of carbs and 1000 diferent styles of jets . my manual says i have a TMX 10A, im assuming thats a 38mm but i forgot to measure it and i dont know these carbs for shit

Put a PWK on it and call it good

i would never own a mikuni on my 500, this is on the 250 motor. im going to run it a few times before i get rid of it

Put your PWK on it....

Stoffers!!!!

Word!

Tip! the needle #s/letters are all over the place.

Most of the time the nozzle that the needle slides into is changed.
Example my old RM stock was a Q-8 but needed a R-2.

I think her quad went from a O-6 to O-8. Both richer.

See if FMF.com has the 250 specs.

Oh and last I read in one of the mags said the last years of the CR250 the jetting was all over the place and never really got it dialed in.

i know a guy running a mikuni from a 2000 250? on a 500 thats over 80hp

yeah, the needles are weird #'s and letters, really confusing, like the xx41j and xx40j and on either size on a xx46m which is the middle. I'm running a r-8 needle jet and 40j needle and still have starting issues, but otherwise in runs tits.
the carb you have is a tmx, most components are shared with all the '01+cr250s and uses the same jets as other TM series.
and yes, its a 38mm

i dont see why they would take a simple thing and make it complicated

Getting something to run good on the main jet is the easy part
