If it runs better with the choke part way on... that means it's starving for fuel.
I had this same problem with a customers bike. After checking EVERYTHING ELSE first... I started drilling the jet a tiny bit at a time and test riding it each time; & it started running a little better every time!!
I have two other jets one from my old carb and one from the free replacment i will chang it tonight I think you hit the needle on the head!
Do you think I shound change the needle too?
