Starting Issue - AGAIN

[darrsi]

Went to start the bike outside work last night and had to hold the starter button for a few seconds rather than it instantly firing up like it normally does, then there was an almighty backfire before it sprung to life.


Again tonight, not as bad as yesterday, but it was definitely hesitant before starting compared to normal.


I get the feeling something's about to peg out but i'm not sure what? The bike runs absolutely fine otherwise.


Quite recently had:


New battery
New reg/rectifier
New fuel filter
New Iridium plugs
New TPS
Air filter cleaned and re-oiled
Carbs balanced by me
I did have an issue with the side stand switch, but ended up bypassing it completely, so that's ruled out.


What am i missing?
Apart from this possible upcoming issue the bike is running as sweet as a nut otherwise.


Any thoughts welcome.


Thanks, D.
