Question about Motorcycles
Rebuilt the carb, now bike runs like crap unless the choke is slightly engaged. Why?
Your Air/Fuel Mixture is wrong.. Your carb is getting too much air and not enough fuel. Have you adjusted the jet screw setting? Does it have one?

sounds like the main jets are partly pluged, you must remve all brass jets and seats including needle jet and its slide soak in carb cleaner and blow out with compressed air only.. hold up to bright light to verify if all are clean. jim

Sounds a lot like fouled fuel jets in your carb; you may have a little work to do.
If the jets do not allow sufficient fuel to pass, using the choke can 'cheat' the carburetor by restricting the flow of air and restoring the fuel-air ratio. You can't ignore this problem since the 'cheated' condition does not let the engine develop the power for which it was designed.

SOURCE: not sure why my bike wont start
How long did the bike set un-used? After years, gasoline turns into varnish after evaporation of the aromatic hydrocarbons. I've actually seen a substance like molasses in all the carbs and the gas tank. Take a bowl off of a carb and see what you find. If it has gone to varnish, you will need to disassemble every component that gasoline touches as a liquid and re-build and clean out the gunk. (yes, gas tank too and the diverter valve) This is a common problem.
