Question about Harley Davidson XL 1200 C Sportster Custom Motorcycles
Since you didn't say anything about the engine not cranking over, I'm going to assume that the engine is turning over fine and everything else is as well. Some people do experience trouble getting their bike started on cold mornings because they are not familiar with how the enricher circuit works.
The enricher circuit works differently from the old fashioned "choke" found on older bikes. To get the enricher to work as it should, the throttle must be completely closed. A lot of people get ready to start their bikes and open the throttle just a bit. Do not do this with an enricher like your bike is equipped with. If you do, the air the engine draws in does not pass through the enricher passage but rather through the carb throat itself and then the mixture is too lean to get the bike to start.
The way I tell everyone to start the bike is first turn on the fuel at the petcock. If you're bike has the original petcock, it is vacuum operated and you don't have to turn it on, it'll turn itself on. Then, prime the carb by twisting the throttle grip two or three times. Then, turn the switch on and with the throttle completely closed, push the "start" button. The engine should fire right up. If not, twist the throttle one more time and try again. If it doesn't start up then, you may have a problem.
If you get the engine flooded and you smell gasoline strongly. Turn the throttle wide open, then push and hold the start button. Do not hold the button for over 15 seconds at a time under any circumstances or you may burn up the starter.
If this doesn't work, please repost and give me more information about what the bike is or is not doing.
