Resurrecting this post from the dead in case anybody has had cold starting issues after winter storage.
To preface - I put my bike away at the end of November. Fuel (91 octane no ethanol) stabilized and topped up, battery on a tender, stored in a cold garage (never below freezing mind you).
Pulled it out of the garage today - wouldnt start. Battery was fine and it kept cranking and cranking - but nothing. I tried half throttle, full throttle and only got a couple little stumbles out of it as if it wanted to start. I cranked (5 seconds at a time) until the battery could no longer crank, but would still run the lights.
Charged the battery again for a few hours, and then I started by flipping the kill switch on and off a few times to get the fuel pump going (read this from searching the forum as another user suggested it). Then I gave it a little throttle and cranked it. Little by little it got closer and closer to starting. I kept repeating the cycle - getting the fuel pump priming a few times before trying to start it, then laying on the starter for a few seconds at a time, giving it time to breath so I didn't burn it out.
Lo' and behold it finally gave. It rev'd up to 4K rpm for a while and then eventually settled in as it approached operating temperature.
I read here from another user suggesting the fuel lines lose pressure over time, and I assume that's what happened to mine as it sat for 4.5months. Just took a while to get the fuel to where it needed to be again, as opposed to settling way down in the tank.
Best of luck to anybody that has this issue. I know searching this forum was very helpful to me in getting it started - just thought I'd help consolidate.
