I am new to motorcycles. I have a 2001 Fatboy with a carberator. Early this morning when I first started riding bike was running perfect. I drove like six miles it started missing and cut off. The temperature was 28 degrees Fahrenheit.
I let it sit for a few minutes and it cranked up running perfect for a few miles. Then it went to missing and cut off again. I did this like five times till I got it home. This afternoon it was like 50 degrees Fahrenheit and it run perfect for like 25 miles.
Do I have water in the gas and its freezing then clogging the line or what. Then it warms up and the ice melts in the tank and it runs great. I'm just trying to figure out what's going on.
I rode it awhile back when it was below freezing and it did the same only one time though then it went running fine.
Any advice would appreciated.

 

I would take a look into anything that might cause a drop in fuel pressure/volume. Air leaks, filters, etc.

 

I'm cleaning the tank and changing the fuel filter.

 

My guess would be:

Dirty fuel filter
Clogged gas cap vent

Have had both happen to me & symptoms were exactly the same.

 

pull the petcock out of the tank, you will see the problem.
ten minute fix , zero cost

 

My bet is crank pos sensor or coil failing.

 

1) Push the enrichener **** in after the engine starts warming up, leaving it pulled out will foul plugs.
2) Drive with the fuel cap loose on the tank, if the bike runs then check for a plugged vent.
3) Crank position Sensor going/gone out. Little black sensor by the oil filter.

 

This bike has that epoxy coating on the inside. The Harley shop has removed a lot of it a and replaced the the strainer. We will see of it fixes the problem.

 

tank liner clogging the petcock strainer , you did see the problem.
been there ,done that ....liners are crap

 

The dealership cleaned the tank and put in a new strainer. They replaced the fuel lines also. Seems to be running great now
