Rough Starting

Happy Thanksgiving day to the fellow Canucks
Now a little background info.
I have a 1999 VFR800 ( 50,000km )( 30,000 miles ) that I rescued a few years ago from out west and since there was no fitness inspection done in that part of the county I spent a winter going through it from one end to the other, new tires, front end redo with new bushing springs etc, brakes , brakes bleed , new charging regulator system, valves checked, new O rings everywhere in the cooling system ( thanks for that suggestion Capt. ) fuel injectors checked and cleaned by a Honda Tech I know etc etc.
The problem I have is that when I go to start it after sitting a few days it is a bitch to start, I have to use the choke full on and crank it over a few times ( three or four cycles ) before she will catch and run.
Once she is warmed up or after a ride she will fire up all day at the touch of the starter button
So since it is very close to winter sleep for the old girl I figured it is time to have you guys feed me your thoughts as where I should start looking, personally I am thinking it is acting like the Starter Valves are not right, perhaps the fuel pump is loosing its prime after sitting around or maybe I have a bad injector hose somewhere\
I am not sure as you can see so any thoughts or comments will be great to have before I dig in

 

Spark plugs ?

 

I have never worked on a 5th Gen, but since it fires so nicely when warmed up, my next move would be to verify the operation of the Starter Valves. Eliminate that possibility, because if you didn't do it, how do you know it's working properly. Especially with the work that was done on, and around, the injection system.

If this was one of my carb bikes with those symptoms, the first thing I would do would be to verify that my enrichening system was working properly. Like is the cable functioning properly and is it, and the linkage its moving, adjusted properly to achieve full engagement.

Good luck!
