So a huge thank you! Anyway, I got the hawk, it bogged down in 5th gear/ran lean. So I got the vm26 clone and some jets and got to work. I started with the recommended 110 main, 25 pilot, air/fuel mixture 1 1/2 turns from seated. Bike won't idle. I try adjusting the mixture screw way out, still no idle. I repeat this process with a 27.5 and then 30 pilot jet and still no success. Also if I ride it tries to GALLOP in first gear, but will die if I let of the throttle or shift to neutral. I'm in SE Michigan, ~820ft, it's been in the 70s. Last thing of note, it actually idled/did low fears fine with the stock carb, was only bad/noticably lean in 4th/5th. I'm really hoping megadan will jump in here

I bought a Mikuni carburetor to replace the stock one. It runs great
