So to bring back a dead thread, I did want to mention I figured out the issue. The barrel for the enriching valve was leaking air, so it was just running super super rich, despite the spark plug looking clean.
I ponied up and got the Lectron carb. The throttle response is weirdly fast, like a tuned EFI bike. It has power everywhere. Also, these don't have a choke or enrichening valve, so you just start your bike, it's weird. Lol
PS: never mind the incorrect hose clamps, the correct size ones are already installed...
