Hi Art,
Fully open throttle worked a treat for me Art, permanently! As I say, problem has gone away now. Normal starting resumed. I guess sometimes engines need a little coaxing. Like humans, they're not perfect.... 👍

At full throttle mine will not start, that is how I test the battery CCA's and that is how it should be. However, if you fully open the throttle and then shut it off after say 5 to 10 seconds of cranking, similar to the flooded engine start procedure, then it should start but while the throttle remains fully open it should not start. If it does start at full throttle then there must be a fault in the Starter Circuit or Engine Control Module.

Don't take my word for it, its all there in the Owners Manual.

Honda Owners Manuals - CBF1000/A (MKI) page 62 and CBF1000FA (MKII)  page 58

The engine will not start if the throttle is fully open (because the electronic control module cuts off the fuel supply).

Hi Art,
I think you need to read my personal start up procedure  again? Throttle only held open while fuel pump cycles? I also have an open mind 👍🤗

Note to self I need to pay more attention, more or less the flooded engine start up procedure then.

I'll go sit on the naughty step

I wonder what exactly happens when you do that. I believe it works but cannot puzzle out why it does.

Well i tried the method yesterday and today and it seems to work.
It does (re)start much easier, i cant really figure out why it would. but it does.

@Art, I will test the battery voltages, you might be on to something.

Glad it worked for you J.
As I've said, mine now seems to start ad normal without this procedure, so maybe something in ECU or sensor has righted itself? Don't know.... but I did have to carry out this start-up procedure for about a year. Also during this period my bike was showing unusually good fuel consumption according to the dash read-out? This may have been linked to the bad Hot Start problem?
Maybe yours will right itself too....
All the best

Hey guys,

the subject kida got away from me but i just wanted to rapport that a new battery solved the issue completely.
Now i notice the difference in the battery's starting performance.
ticks over with ease, thanks again for the advice.
