cold starting at about 39 degrees choke on fully, starts. then takes forever to get full throttle. won't open up fully until very warm. after warm runs fine
I can see you apparently have never lived in a cold area.
The choke is used to help start the bike, and then you take it off gradually.
Mine will start below zero and burp, piss and cough till it is warm, but their is nothing wrong with it.
I know others have said make sure the choke is FULL on. You responded you had the choke on, well to please an old fart, please read and try it.
Choke lever, press it down until you hit resistance, now push it another 1/2 " down. NO, you won't break the cable, you are just trying to slide 6 enricher's into the choking position. The black handle should be pointing straight at the starter button when it is full on, or flat.
Now, please go check it out and report back... Old fart says thanks.
As Forrest Gump would say:
“That's all I have to say about that.”
