A stupid noob question??
« on: July 29, 2010, 01:40:21 PM »
Okay i know it sounds dumb. But where is the choke on a 2004 yz250? Im curious if there is one. The bike starts 1st kick regardless. but i know it must have a choke.

At the front left of carb. Just in front of the vent hoses.
It has a black knob on it.

Okay i found the actual "choke" Knob. But that brings me to the second question. How does it work? when i pull up on it, it just springs back down??

You need to pull up harder until it "clicks"It should stay.If not,unscrew it and have a look.If your bike starts without it,you're jetted too rich.

Okay it does click. So im guessing with a cold start i should turn the gas on then choke it then give her a kick. are you supposed to leave it choked for a bit or just start it with choke then turn it off?

If the bike is jetted properly you should only need the choke on 5 seconds or so.
It will depend on air temp tho.
Just keep the bike going with abit of throttle.

What I usually do with my bike (which is jetted quite lean) is to turn on the gas, turn on the choke, then give it a couple gentle kicks to get things going in the crankcase.  Then when I kick it for real, I keep the throttle off and it usually fires pretty quick.  I leave it running with the choke on for a few seconds, then when I turn it off I listen to whether it wants to die or not.  If it sounds like it's going downhill I'll put the choke on a little longer, then try again.  Usually after a month or so of sitting it's good to go in well under a minute.

Is this Maico a 440 or only a 400?  Well in all the confusion, I forgot myself.
But considering this is a 1978 Magnum, the best-handling bike in the world, you have to ask yourself one question.

I have 2 bikes that do not have chokes, they have what you call a tickler.  The tickler does one of three things.

1. Nothing
2. Primes the engine so it can start
3. Floods the engine

I have found that it's usually 1 & 3 for me, I've never mastered the art of cocegas. 

So, for those bikes I have a most unusual starting method.  I take a hose and blow into the overflow for a few seconds.  Then I just kick it with the throttle closed and it usually starts within a kick or two.

Yea + i think the heat here in Florida makes the choke unnecessary. You're lookin at 90+ degree weather every day...

I've been to Florida a couple of times, I can't imagine how an engine can run in that air.  Honestly I think there's less humidity at the bottom of the Columbia River.

#'s 1 & 3.....LMFAO :D :D :D Just like being in Amal country.

BTW braap, regardless of your conditions,if you can start without choke,you're too rich off the bottom for those conditions.
