    It's probably the stepper motor ( auto choke mechanism) .
    It'll most likely need a clean with some carb cleaner .
    ..
    Try adding a little throttle when starting from cold .
    Make sure your battery is fully charged.

    Hope this helps.

    Hi Rick, thank you very much for your reply, I really appreciate it!!!

    Is that the one placed at the upper right side of the air box, correct???

    I will do as you suggest, I will take advantage of the fact that I already removed the gas tank (to check for water or any dirt) and that I also removed the air box cover (to check the condition of the air filter).

    Any other recommendations considering I disassembled all of that???

    Last January I installed it a new gas pump, cleaned the injectors (they were fine), and put in a new air filter and new spark plugs.

    By the way: the intake and the exhaust are unobstructed. The air filter is like new.

    To remove the stepper piston from the plastic cylinder, DON'T twist it. That is likely to break the stepper mechanism that stops the piston from rotating. Push it out if it is too tight to slip out.
    If it is very tight, once you get it apart, clean the cylinder & piston with carby cleaner to remove the varnish residues. If the piston is still tight after that, use some 400 - 800 grit emery paper on it to solve the problem. It needs to be a sliding fit, not loose or firm. Don't abrade the plastic cylinder, you'll mark it.

    It was a combination of:

    - Bad fuel.
    - Some moisture where the spark plugs & coils are.
    - Weak battery.
    - Sticky stepper motor.
