I'm going to grab the mikuni I had on my WR300 and see if that will fit.
I jetted that once and it was perfect for 700hrs. Stu Sent from my SM-N950F using Tapatalk |

It'll let you know if the carb is at fault or something else at minimum.
Very strange that the idle screw has no effect. Has the tip been snapped off it or something similar? Air screw can have little effect until you get everything else where it needs to be. |

I would double check the crank seals. Especially the one on the clutch side as it will consume trans oil and make jetting impossible.

Sounds like a worn carb. What would be a needle jet in a Mikuni and made of brass is not replaceable on a Keihin and aluminum. The needle will over time wear that hole larger and make for a rich low throttle mixture. I had to go to a larger (leaner) base diameter needle on my bike with similar issue. Same needle with an "E" first letter in stead of the earlier "C" first letter. Now I could turn the idle down and adjust the air screw with results. A new carb is the real solution, but mine is a RB modded carb and I like it again with this change.

So....swapped out the Airstriker for a Mikuni TMXX38 from a 2011 Husqvarna WR300...
Wow...now I know why everyone falls in love with these bikes!!! Brilliant!! Smooth, powerful and Linear from the bottom all through the rev range! Love it. Thank you to everyone who has helped out, it's so hard to diagnose a worn carb but we got there in the end!!! Stu Sent from my SM-N950F using Tapatalk |
