Carbs and Poor starting
Discussion
Morning,
I have a 2002 900 diversion, 95k miles on it - choke bar hasn't worked in years.
When really cold I sit the hair drier under the fuel tank to unfreeze any droplets in the jets - then starts first time.
Weather is not cold anymore but there is still a reluctance to start - 10 mins or so. It might cough for a bit and then nothing eventually the cough become a few coughs then if held on the starter a steady cough, then it will start.
I have had the same issue with an old car where a potential pin hole somewhere in the pipe / tank system is causing the fuel to drain backwards so the pump has to work for 10 mins to drive fuel to the engine.
Why with a full tank sitting above the carbs would the bike exhibit the same fault / issue ?
To stop at a petrol station is starts first time, to start it at 5pm to drive home again "normally" first time, but if left a day or two, it is reluctant.
As it runs fine, and starts after a short stop, I am working on the basis that it gets a good spark, it has air, so it must be fuel related ?
thanks
Del

Sounds like fixing the choke would be the ideal solution.
My 2 carb'd bikes need some kind of choke to start unless warm (as in just been running, not just a warm day).
I say 'kind of' because the Monster has FCR carbs without chokes but it needs a couple of 'squirts' of fuel down it using the accelerator pumps or it won't start and then it splutters and coughs until there's a bit of temperature in it. The Guzzi on the other hand needs choke to start but then straight off or it bogs down.
But if it's not been serviced for 65,000 miles it could probably do with some TLC...

The oil leaks keeps the rust at bay....
