    whats the coldest temperature that these bikes can run; is it possible to modify them to make it run at even lower temperatures?

    metal plates on the side of the carb would direct air from the engine around the carb.
    a air box or with hose or pipe that gets heated next to the engine would heat the intake air. and a drop of drygas in the tank would keep the gas from freezing. i bought my engine after winter was over and havnt used my bike in the winter yet,but i will and i belive it will run even at artic temperatures. plus i keep my bike in my apartment,no cold starts here. and the engine stays plenty hot while running,enough i could cook on it like a barbique.

    One of our members is from Moscow Russia and has posted videos of himself and his club members riding in the dead of winter...Cold enough for you?
    Actually there might be a limit but it has to be pretty darn cold. I've riden in winter often in Denver Colorado and when it's real cold I'll give the carb a shot of quick-start, ether, and after a few seconds of warm up and some choke my engines perform the same as they do in summer; maybe a little better. Hope this answers your question.

    I'll have to find that out this winter. I had a Harley-Davidson that started one night at 13 below.

    The coldest I've ever run anything at was -22 degrees F. These motorized bicycle engine kits will fire at just about any temp. you want to ride them in.

    The bike will start with a little extra priming, you however, will need mods. ;)

    I think at -20 F I'd be more worried about the tires and tubes cracking! For that matter I would also be worried about small bits like fingers and toes breaking off!

    at really cold temps, you could have cold seize issues just as a snowmobile can have.... might also be a good idea to change jetting on the carb but, it should run at any temp..

    i have ridden at zero and below but even though it gets cold here we get alot of sunshine, never had a problem starting or running even the 4 stroke starts up after a couple of choked pulls

    -20 celcius, not -20 fahrenheit, mind you. i see people running their gas snow blowers during the winter all the time, so it safe to assume the bike will rund as well?

    ok its starting to get cold here. i had a heck of a time starting the engine on a ride to the library the other day, i tried choke open, choke closed, half choke, but it took half the trip to get it to start with the choke fully open, pedaling up to speed and popping the clutch over and over. would using the tickler have helped in this situation? once i got it started it ran pretty well, maybe even better than during warm temperatures.

    It's easy to flood a engine when it's really cold. Try a 2 sec push on the primer and no choke. I'm with bike joe on this one you will need more mods than the bike motor will. It should run at any USA stateside temp.

    If you can't store the bike inside where it's warm I'd suggest getting an electric pipe wrap and wrapping it around the engine & carb. They do something simular with big trucks (Block heaters) and if you can get diesel to start anything'll start!

    2 second push on the tickler and1/2 choke. Still took it 50 yards to start, and that was at 50 degrees.
    Because it gets dark around 7 here, I only get to ride on weekends now.

    I feel your pain Barely, although the temps here are a bit higher. I just got my bike all working nice, and the temperature rapidly dropped.

    But think of all the great winter mods that will pop up! Maybe skis instead of tires, and treads haha.
