Malaysia / Oregon (winter)...our climates are very different, and theoretically maybe it shouldn't matter, but I've had 2 difficult start ups the the last 2 winters as I've posted [url=http://cb1100forum.com/forum/showthread.php?tid=13697]HERE.
My start-up display seemed to indicate all normal, fuel pump whir was there, bike cranks great but would not turn over. I normally don't touch the throttle upon start-up. But both times when the bike behaved like this, I got the bike to start by opening the throttle about 1/4. Throttle fullly open would not start, just when it was open a little. It turned right over after 2 seconds, sputtered, and then ran smoothly. Each start-up after this was fine. No throttle necessary just like before, zero issues afterwards.
The only two issues in common for these two instances--which happened a year apart from each other--were 1) bike sat for 1 week to 10 days, and 2) cold weather (32-37F).
Maybe try starting bike with throttle 1/4 open to see if that helps.
