ok my dad and i were doing dougnonts on the snow covered road yesterday.all of the sudden it stalled like it ran out of gas. we let it sit for like 30sec. and it started up.ever sinve yesterday it has been spitting and sputtering.whats wrong it idles fine but when u hit the gas it hits 5mph and it starts to sputter for 30sec.oh by the way it is a yerf dog 150cc.

Same thing happens with ours. Its just cause its cold outside. Throw a heater on it for about half an hour and then run it half throttle for about 15 minutes before going full.

Could be the weather or maybe some junk got dislodged in the carb doing the doughnuts.

the intake could be freezeing up causing the fuel and air mixture to turn to ice crystals. had that problem on baja bugs I built

I'm thinking there's something disrupting fuel flow. Is there an inline fuel filter between the tank and the carb? What about bad gas, water in the tank? Some of the older bikes I've worked on would idle fine but stumble when getting on the gas. This was always caused by either crap in the carb or in the gas or a dirty fuel filter.

I'm not an expert on the carbs that come on a Yerf Dog but they should work essentially the same as any other...meaning, they run better clean...just my two cents.

Seems to me the yerfs would have an inline just like the rest of the majority of buggies. Can't remember. Been a while since we had ours.

[yerf3206]

yea they have an inline.i think it is just the cold.i just want to no if it will hurt the motor or anything.

[Sheckells29]

It shouldn't hurt it at all. And just throw a heater on it. Thats what ive been doing and it helps it start up and run a hell of a lot better.
