    So i killed the battery by leaving the park light on by mistake, so i just recharged it to full.

    When i go to start up the bike cold, i play with the choke about and put it about 3/4 the way open, and the bike just wont kick. I click the starter and it is acting in a way as if the choke isnt even open? Like, i try to start and the RPM is at less than 1000 and it just wont start.

    Then when i give it some gas while holding the starter (With the choke still 3/4) it will rev up and THEN it will kick, and then a few seconds in the choke will start going to work and the RPM needle will spike to around 2-3k while the bike warms up.

    Why do i need to apply gas and why does it seem like opening the choke isnt doing anything? The RPM needle when i dont touch the throttle is below 1000 and therefore the bike will not start up, it will kick a little and die out, or i hold the started and it just keeps trying and doesn't start.

    Is that normal that i need to give it gas to start it?

    I also checked when it was warmed up and it started fine, 1 quick press of the electric starter no problem. So i dont think its a starter issue?

    Cold start routine should be as follows:

    -Petcock on PRI for 10~20 seconds if bike hasn't run recently, otherwise just leave in "ON."

    -FULL "choke" (it's not really a choke, it's an enrichening circuit.)

    -NO THROTTLE, hit the button. The bike should start, stumble a bit, and then the revs start to rise. Begin to SLOWLY and GRADUALLY reduce the amount of choke so the bike holds around 2K as it warms up, you will need to continually reduce the amount of choke during warmup so it won't race.

    At this point we still haven't TOUCHED the throttle yet. You can go ahead and "blip" it once it's begun warming up.

    If it doesn't work that way, you need some carb cleaning/float level attention.

    Thanks for the post. What do you mean "It isnt a choke, but an enrichment circuit" ?? I actually noticed that when i move my choke about 1/4 of the way, it actually isn't even opened at all yet. For some reason it doesnt start to open until i move it a good half way (When i move the choke and look at the carburetor i realized that what i thought was half open was really BARELY opened)

    So for starting the maxim 650 i should

    Open choke all the way?
    Bike will sputter to life and then rev up on its own, adjust choke so RPM is around 2000?
    Do not touch throttle at all?

    Is it bad to touch the throttle to get it started?

    But yeah i think the issue was the choke not being opened enough. I was moving the choke lever about 3/4 open (Which really wasnt enough to get the bike started because when i look at the carburetor it was barely opened)

    So i should always set the choke full to cold start and then adjust while the bike revs up?

    edit: wow wow wait, i just realized what you said about the PRI position. What?? The guy told me i never need to touch that valve, only to put it on reserve if i ran out of gas.

    Now youre saying i should put it in PRI position on a cold start for 10-20 seconds, then turn it back to the "On position" and then choke + Electric start the bike?
