It's the circular-shaped piece that holds the needle in place. Proper orientation of those parts...

So I think I'm going to change from 155 to 152.5 main and if the mid-range symptoms persist, I'll just shave a bit more off the spacer. Thanks for the help, guys. Really appreciate it. Good stuff.

So I changed the Jet to a 152.5 and everything got worse. At around 4k-5k rpm, wot, the bike jerks back and forth really hard. With the 155 main, there was significantly less hesitation. Should I try a 150 main? That seems too small for my pretty much straight pipe exhaust and big k&n intake, so I'm not sure. Any help would be appreciated. Thanks.

Sorry,........many here call it an enrichment valve, probably because it doesn't shut off the air like a butterfly choke does. I myself call it a choke so as to not confuse those who don't know there is a difference.

But at most any speed....short of WOT, pulling the knob 1 click will tell you real quick whether it needs more fuel or less.

When mine is warmed up, I can't even get it to the first notch without getting major stuttering and chugging and smoking. Going to the first notch then causes the engine to die. On cold start below 60 degrees, it needs it out to the first notch, and that works all the way down to below freezing. I never need to pull it out any further than that, as the motor starts chugging and spitting then.
