Now that I have sorted out the flooding issue, here is an oddity that doesn't make sense.
When I first start the bike after sitting for more than a few hours, overnight etc., she's a little testy. With a bit of choke she fires up and idles a bit choppy while ostensibly warming up. More choke will raise the RPMs, and cutting the choke drops them. Like it should. Throttle with the choke on causes it to stumble a bit.
Even after several minutes of warming up, it tries to fold on me if I cut the choke. But here is the weird part, if I blip the throttle between cutting the choke and the engine folding, it revs and then settles into a nice idle. Thereafter, it will start right up, like a well-behaved warmed up bike.
Basically, it seems like a solid rev to 2,500-3,000 without choke clears some kind of obstacle in the warm up process that merely idling with the choke (even at higher RPMs) never seems to break through.
The dependence on choke normally means the idle circuit is too lean, but once I coax it through the initial start up, the engine idles fine, perhaps still a hair on the rich side.
Unless it is a sign of some deeper problem, this starting hiccup is just a mild annoyance. Warming the engine on choke for a minute is generally enough to prep the bike for the blip through. It just puzzles me that warming the bike on choke for several minutes won't get it over the hump unless I do the blip.
Any ideas?
