I understand that the choke is supposed to be up when starting the engine.

When do I lower it? When the engine has warmed up?

And how much to lower?

Thanks.

I will lower mine within a minute, depending on how cold it is I may run with half to 3/4 choke for a few minutes and then all the way down.

When an engine is cold and has been sitting you want to create a rich or excess fuel condition for starting. The choke does exactly that, it chokes your engine from getting the correct amount of air creating a rich fuel condition. This ensures that fuel gets to the combustion chamber.

Perfectly clear. Thanks.

is it only me or does this happen to anyone else? when i ride my MB all of a sudden it will start surging and losing power, when i stop to check it out i find that my leg brushed the choke lever and put it on (all the way up) any ides on how to fix this? i was thinking of just taping it down as i only use it to kill the motor, and i always have a roll of tape in my bag

antlers, ok.
if you take the air filter off you will se a nut that holds the choke lever on. tighten it up a bit. my MB would actually vibrate the choke into the on position till I done this. The nut will make the choke action a little tighter but then the choke lever will stay where you put it. It doesn't take much tightening though. just enough to make the lever stay where you put it.

the so cal mod, made popular by Norm from Venice Motor bikes, is to hook a rubber band to the choke lever, and then to the motor mount or something. it's classic old school ghetto-tech.

or just tighten it.

i was having a similar problem. i had an aftermarket petcock on the gas tank, and it stuck out at a weird angle. i used to rub my knee on it and shut the fuel off while i was riding.

If yer carb has a tickler/primer you could prolly get away with just removing the choke entirely. I've not actually bothered as I've not had problems w/it - but I also never use it despite ridin' all winter in Maine.
