It used to be that alot of the old racers used to feather the choke control to gain just a little more power from their motorcycles.
Try raising the clip on the carb a notch if you can and see what it does then..
Cleaning off the plug with a wire brush will give you a better clue of what its doing per run..

You actually need to lower the clip a notch to richen it up. Lowering the clip raises the needle, which allows more fuel. |

Ok. I'll lower it. I noticed yesterday a chip off the flange on the exhaust. Wonderful.

At 3100 miles, maybe the thing is getting tired? How's the compression?

Ok, so let me get this right, I need to lower the clip... Maybe all the way down and work it upwards? The plug was dark brown suggesting to me, it was getting near being rich?

Lower the clip one notch at a time and try it, open the choke, mix fresh batch of gas/ oil, check for intake air leak....

Two of my customers bikes would run better with the choke half on.
I drilled the jets a little bigger, & it fixed 'em both!  |

Ok, today at the lowest notch I got a medium gray plug. Bike runs about the same....
I'm stumped.

It's just for putting around the block every other weekend for 15 or 20 minutes, it's not a commuter....
