Hard starting when cold, choke problem?
Normally this bike fires first time, every time.
This morning everything was frosted over pretty well, bucket of water outside had a frozen layer on top.
When I pulled the choke toward me, it seemed like after about 1/2 of the way toward me there was much less resistance than usual. I pulled the choke all the way forward as I usually do.
Dabbed the starter, bike fired immediately, then died after about 3-4 seconds. Dabbed the starter again, same thing. I was able to get it started and kept that way by revving at the low end (working the accelerator pump), it wouldn't rev high in fact it would just cut out totally. So after a few minutes of flogging the poor beast I was able to get a low idle that would hold.
Now as I pushed the choke back to the half-way point, which for me is when about where the rpm's drop, nothing changed. Pushing it beyond that point did seem to make a difference though, where the idle feels like it's about to go too low, this is normal until after about 5 minutes of driving.
Is it possible the choke got stuck in the carb part way and didn't fully engage? I can't really see how, but that's how the symptoms appear. In hindsight, I would have banged the carb where the choke enters while working the choke.
Any thoughts appreciated.
