So I'm in Fort McMurray for 8 months and lately it's been between -5 and -10 when I go riding. I'm having trouble kick starting my 2002 RM125. Everytime I try to start it in the cold I have to pull the plug, let the chamber air out and then it starts with maybe 5 kicks.
I'm trying to understand why this happens. I've started closing the fuel line before the end of my ride and running the bike a bit to take some fuel out of the carb, but it doesn't really help. Since I store the bike in a heated parkade, could the remaining fuel in the carb be vaporising overnight, drifting into the cyclinder and then turning back to liquid as I drive out to the trails? My idle is set pretty high. And I'm buying pump gas which I'd assume is winter gas so it has a lower vaporization point... But if this was the case wouldn't every car parked underground also flood the engine?
Any ideas would be great as its annoying to pull the plug every ride and I don't like kicking too much.
PS: Yes I pull the choke out.
