I think I'm gonna get a bigger carb for the SX and I need to know from experience what sizes will fit it that are bigger than a 27mm

They are just two different catagories of carbs from DG Keihin, but if a 350x carb will work I'll use that and just change the main jet.

i used one off a 300ex on my 85sx that i sold.u have to jet it down and i think i had to use the 300ey intake as well. but the built in accellerator/primer pump made it start alot easier compared to the original carb.
