xr650r uncorked with tm40-6 acc pump jetting

2 posts in this topic

I have a stock uncorked xr650r and i am thinking of replacing the stoch carb with a TM40-6 acc pump.

So anyone with the same setup or any other good ideas on the carb setup, like main, low, needle and acc pump.

I live in sweden at coast

Many thanks

Hey,

I run a somewhat quiet aftermarket pipe, stock headers, uncorked, but NO holes drilled in the side panel. I'm at sea level in Florida. Mikuni TM-40 pumper.

pilot 22.5 --------------------25

air jet (in mouth of carb) 1.2

needle jet Y-4 ----------------Y-6

needle 9DJY2, middle clip------9DJY3 or Y4

main 140 ---------------------145, 147.5 or 150

Left side is what I'm currently running, which is on the leaner side, and gives decent gas mileage. With an open airbox, headers and loud exhaust , go more with the #'s on the right. Good luck.
