Zxr750 cold start unpredictable choke?
Discussion
Just balanced carbs, sorted out and replaced all vacuum hoses in correct order at last after finding diagram.
Bike is flying, runs sweet as a nut, but would just like to cure cold start problem, however it does always start!
I put choke all the way on, bike starts but for a few seconds will idle at just 1100 rpm or thereabouts, after a few seconds idle shoots up, I put choke off slightly, then it will stall. Start bike again, same thing happens but this time when I put choke in slightly it doesn't die, but will sit steady so I just leave it for a few minutes to warm up, putting choke in bit by bit, then everything's ticketyboo, will eventually idle perfectly?
I would just like the choke to make the engine rev to wherever you put the choke at when cold starting, like normal chokes work! :-) Thanks.

My SRAD does the exact same thing, sits nicely at 1100-1200 rpm for a minute or two and then starts to rev up, back the choke off a bit, revs come down again - then shoot up again etc. Once the temp gauge starts to display it settles down and is fine for the rest of the day then. I tried all sorts too; cleaning and balancing the carbs, re-jetting, adjusting the throttle and choke cable freeplay, fiddling with the idle adjuster and checking for air leaks. Non of it made a difference so I just learned to live with it Bike is flying, runs sweet as a nut, but would just like to cure cold start problem, however it does always start!
