How much choke needed for startups?

How much choke do you use for your bikes?
My 750 Seca don't like much choke at all for startups, just a bit. I get it off the choke quickly and have to blip the throttle. Full choke fouls up the plugs pronto!
My 550 Seca likes full choke for startup and has a typical warm up, but you have to get on the road soon with a little choke on, or the plugs will foul.
My Suzuki GS1100G likes full choke, and I ease it off normally as it warms up, then it will idle fine off choke until I'm ready to go.

My 650 is pretty much like your 750 seca.

 

All bikes are different, it's just what works best & can depend on the state of tune, climate ect.

 

depends if there is gas in my carbs

if gas is in there she will start right up with no choke

if not, full choke

 

My 550 is about like your 550. She requires a fair bit of warm up before she'll purr at the stop signs. Of course, the longer I ride her the smoother she runs. Doesn't like to be left unridden for long periods either.

If she's been sitting more than a few days I turn the petcock to Pri for a few seconds and she starts right up with about 80% choke.

 

My 550 Seca is the dame as yours. it needs full choke to start although I move it down to about half choke and let it run on fast idel for a minute or so, then move it down as I ride away.

Both my 550 Secas are pretty much the same; full choke to start, then I go to halfway almost immediately; let it warm up as I'm putting on helmet and gloves, turn it down a bit if it starts racing, and then ride away.

I usually take it off the rest of the way within a few blocks, maybe a mile.
