When my bike is already warm, I need to crack the throttle for it to start, and rev it for a little bit to keep it running. After that it idles fine. It does this regardless of choke position. It will start whether or not I touch the throttle, but won't stay running if I don't.
I recently cleaned carbs, installed the next size up pilot jet and shimmed the needle and the gas is fresh. Battery may be a little tired, but seems to hold a charge for a week or so if sitting. Long enough that I don't think it's an issue.
The same thing happened to me when I test rode it before buying, but at the Tim's, I assumed it was because it only ran with the choke on.
Is this normal? Anything I can do about it
