Best way to choke?

Is it best for bike to choke and let the oils/engine warm, close the choke and ride away OR choke and ride away and then close the choke after 2 - 3 mins of riding?

And yes the first part is better. You should always warm up your bike even if it doesn't have a choke.

I choke and ride, then off until approaching stop, Then choke and repeat.

I find the load to help warm up, otherwise I used to leave it on until warm.
I read standing still is bad because of the uneven distribution of heat.

The whole point of using the choke to warm the bike up is that it isn't under load. If not then just start the thing and ride off.

Or am I just nutz?

Yes, it's like warming up a smoker. Slowly build heat then load it up. I don't imagine FI bikes need it as much as an older carb'd one does, but it doesn't hurt if you've got the time, especially in cold weather as we are having now.

What tiatool said.

I use choke to start the bike, and as soon as the bike is able to idle without it, it goes off and I let the bike finish warming up.

Tbh I could be wrong but my understanding is this.

The bike needs to warm to idle properly.
Riding off is fine but because the internals are smaller than spec and need to expand, engine damage can occur.

The load is fine but high rpm is bad.
The same is true for fuel injection, only it does all the work for you.

all the choke does is reduce the amount of air going through the carb. to create a richer fuel mixture. I always let the bike warm up out of habbit. so i would go with #1. Just dont bang it off the rev limiter for 10 min before its warm....lol

Hmmm.... Sounds legit.

I let the bike warm up on the choke. It gives me time to adjust gear and check the bike before riding off. (this is on my carbed cruiser)

The R1 I usually get to about 130 f and good to go.

In general, choke, start, run briefly to circulate oil to all parts, then ride. While warming up riding, reduce choke as necessary to maintain throttle response and keep idle from going too high.

There are exceptions. Some carb bike are just cold blooded. Had a '92 Seca II that absolutely refused to ride until the engine is good and warm.

Idle warming is bad, because even though engine load is low, the oil pressure is low, so lubrication with the cold and viscous oil is not good. Plus the engine bearings are all designed to work under load. Also, when engine is not doing work driving the bike forward, not as much heat is generated, so warm up time is actually longer. The cooling air flow offsets the moving bike's faster warm up, especially for an air cooled motor, but as long as you go easy the first few minutes of running, engine still warms up faster while moving.

Just make sure to accelerate smoothly and avoid high RPM while warming up.

this holds true for me. with forged pistons it runs like when cold.

My bike-if it's warm out, just Choke at 100%, then lower it to about 10% so it can idle and warm up while I get my gear on, As soon as I have my Helmet and jacket and gloves on it's usually warm up--Now in cold weather like this? It takes my bike a good 5 minutes before it's even running properly on all 4 cylinders, so I have to have it at 100% Choke to START IT--close it to about 50%...If I'm in a hurry, Kick the over-jump on it and hold the throttle open to about 3K Rpm's and ride off--Though it's a little awkward for me to be riding and all of a sudden the other 2 cylinders start firing correct. It's a "Man This bike is running like --THERE WE GO"

The also long winded route--Warm up the bike just tile the case gets warm--Shut it off let the heat warm up the Carb's--Turn on the bike and it'll be good to go--That's just MY bike though--I have no clue what kind of bike you're talking about nor how it performs in cold weather.

Its a 04 Shadow Aero... I had to hold choke full on for a good 2 mins at least in 40 degree weather. Any less, engine stops.
