Hawk 250 clone carb tuning issues

Hey all, I've searched but can't find anyone asking this particular question. Little backstory, I'm new to the hawk life (absolutely love it) and have spent hours on here learning what I can. 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
