    Choke RPM

    What RPM should a 450 go up to with the choke fully activated? I've noticed that it would rev at about 1800 RPM previously, but now it's going up to nearly 3000 RPM. Without the choke, it's still the same, about 1000 RPM. Thanks in advance for your help.

    Well, my '82 11E, which needs full choke on cold starts, immediately starts to increase to 3,000 or more if the choke is not quickly backed off. Cycle World said that is normal.

    I would adjust the choke after start up so she revs about 2k for a minute, then slowly back off until it holds a nice idle speed (1,200 rpm) without any choke.

    You can ride it away while still on the choke.

      Thanks for your reply. It seems that it's normal then. I might have not been pulling the choke out all the way (mine is situated under the tank).
