Cold starting issues

[Foggy19]

Hi newbie to this forum I have a 2008 GS1200, when I try and start the bike in the morning or anytime it has stood and cooled down, it is very hard to start, it cranks fine but struggles to fire, as if there's a fuel shortage, if I open the throttle it will eventually catch, I then have to leave it to tick over, if I try to open the throttle it dies, as soon as it's warm it runs and revs ok, checked valve clearance checked fuel filter, replaced fuel pump controller. I have run out of ideas any suggestions much appreciated.
Regards

If in doubt always check the coils.

2008 models had the black coils that will probably be lumpy and smell burnt by now. If they do smell of hot electrical insulation buy two because they both fail around the same time.

I would have thought coils would cause the fault regardless of bike temperature? if anything they would get worse when hotter?

there's a number of temp sensors on the bike, I would get the fault codes checked, from memory there's one for air, one for oil and two in the heads (on some models?)

Balance throttle bodies and do a TPS reset, then see how it goes.
