You can forget about those jet sizes altogether.
Start with a #128 or #132. Corrected for altitude.

So you took the main out and didn't look to see what size it was?
Mine was a #132. Sorry about the width!

Default Now I'm confused


So WestOZ, Your stock main jet was a 132, and you replaced it with what?
Or you didn't replace it?

This is true if you stick with the #35 pilot you can keep turning the screw out as far as you want and it doesnt richen up and its harder to start with #35. change to a #40 and its better, better low end response and better starting, you'll be much happier KA92064-1108

I've had the #40 in for a while. Runs a tad rich off idle to 1/4 throttle. Going down to a #38 (KLR650.) Worth a try.

I'm running the stock AUS needle (N1RX) raised 1.5 mm. It's about right.
Just gotta tweak out the richness down low.
