Re: choke how to use it!
All bikes are different - all carbs are different. That's the first thing to understand. My ZZR is fine riding with the choke on for 2 minutes, doesn't foul my plugs. My R6 doesn't require it, I start up with full choke until the idle (not the temperature) runs up, it usually peaks at 4.2k with full choke, I try to cut the choke by 3krpm. At the first idle peak, I cut back to around 1/2 choke and get my gear on. By the time I'm done I turn the choke off - depending on the outside temperature, sometimes she's warm, sometimes she still needs a minute but the engine can sustain combustion.
You need to use choke for a little time as is necessary to keep the engine running. I can cut my choke after about 15 seconds, the engine will stay on, but I don't because it idles at 1krpm for a few minutes if I do that. I prefer to cut the choke when the engine can idle at its running speed (I keep my idle at 1.3krpm), not below.
As for idling - there's no reason not to idle in neutral, matter of fact, I'm not sure where else you'd like to idle.
As for riding with the choke on, like I said above, my ZZR does it without fouling the plugs. On most bikes, if you run with the choke on you'll be fouling the plugs up fast. It doesn't take long either a 1 or 2 minute ride with full choke is enough to demand a clean up on the plugs. Long story short, don't ride with your choke on, not even partially.
If you find that you MUST ride with your choke on to keep the bike running for a few minutes, that's NOT normal and you need to check your carbs, A/F ratio and fuel pump, filter and lines.
