Hi, does this sound like a choke cable adjustment?

Bike will Idol around 900rpm but only if the choke is on does the title diagnosis seem correct?

Quick facts;
Starts with a flooded engine? choke on.
(Why I think its a choke cable adjustment)
Symptoms of a lean air mixture, snapping?
(Had some old fuel I think has burned off)
Symptoms of a rich fuel mix backfiring?
(A louder more volatile sound)

I don't want to damage the bike by running the mixture too lean or too rich.
I guess what would help is knowing how fast the bike should be idoling.
How it should sound, at the correct mixture.

Thanks

Did you try turning the idle adjustment knob with the choke off? Should be set to +/-1100 RPM

Thanks John! Its a little more difficult for it to start, I'd be scared to keep it far from my charger.
Any other suggestions are greatly appreciated I added a little 'Gumout' to the fuel mix, carb and injector cleaner. It was outside for a season, I changed the oil, cleaned the airboxes, spark plugs. New fuel, replaced and or oiled the cables.

Actually I can't get the flooded engine to start in the normal way by closing the choke and opening the throttle.

These bikes can be hard to cold start, I have to adjust my idle when I start sometimes and when it warms up I adjust it back down. Just try and start her near 3/4 to full choke once the rpms start to pick up back off the choke and adjust your idle. The choke cables cannot be adjusted, the choke system is an enriching channel. If its not firing sometimes I have to play with how much choke I give her. For a little ease if you know your battery is charged but shes still really hard to fire up try new plugs, the irridiums helped my cold starts.

Well that did the trick I took it around at different times this evening, even stalled it started just fine.
I think I'll change the plugs just for fun.

Thanks, C

If you have a conventional wet cell battery that is more than 2 years old, you may want to change it out for a MF-AGM like this one too.

And get iridium plugs, which should last for 100,000 miles or more.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

Got the battery late 09! Love it. I'm comfortable with the engine, my biggest problem are the forks which may have been bent in a low speed dump.
