minor stalling issue

Though I have been riding the bicycle a lot more than the motorcycles I have managed to start riding the newest commando I bought. It finally runs well after a year of work and has proved to be very reliable this summer. I has one small issue I believe to be a fueling issue. The bike has a single amal sleeved and pazon electronic ignition. It starts first kick and once warm idles nicely at 600 rpms, never dies never falters. After riding it for awhile and stopping off somewhere I kick it and it wants to die immediately unless I give it throttle to keep it idling above 1000 rpms, even at 1000 rpms it seems to wander up and down. Occassionally it doesn't want to start once hot. Generally the idle issue lasts a few minutes and then the bike returns to it's flawless state of tune. If it doesn't seem to want to start at all once hot I have found holding the throttle wide open at least gets it to fire. I tried leaving the fuel off until I start it. I tried tickling it before starting it , but neither seems to help. This isn't a major problem just wants to start hard when hot and is bothersome and I'd like to fix it any suggestions?

Sounds to me as though it's a little too rich. Could be the float level is too high and or the petrol tap is leaking causing fuel to evaporate and condensate in to the inlet. Try before switching the motor off close the fuel tap and give the motor time to use up what fuel is left in the carb.

Ticking over at 600 is groovy and all but you are on that fine line. You really don't want to idle that low for oil starvation and what not. Re-adjust the carb for 800 to 1000. I say re-adjust because just turning up the idle screw may not help with the stall out as much as with the combination of both idle screw and mixture screw.

Perfection is very very very very relative with these thing. Tune for best overall running rather than just one aspect like a groovy low rpm tickover.

I would raise the tickover as advised, and richen the the slow running side. Any engine that runs wants to run and then dies is usually due to fuel starvation / weak mixture. At low tickover the carb will drawing less air into the venturi and therfore sucking less fuel.

To rich or not rich enough? Got both answers here. I can adjust the idle easy enough. If the consensus is the fuel mixture needs to be adjusted I can do that first and then raise the idle a bit, but again to rich or to lean, thanks for the replies so far.
