Why is my VStar 1100 idling rough and backfiring?
This problem might ‘solve itself’ with a little time. As far as the backfire – this might be either from the carb issue or it could be related to that rattle you mentioned – you could have a loose connection at or near the head – this can **** air and cause a backfire. I hope this helped! You can’t post conmments that contain an email address.

Why does my motorcycle backfire all the time?
If your motorcycle only backfires at very specific times, such as when it’s really cold, really hot, when it rains, when you turn left, etc. then you could possibly have the issue of intermittent spark.
What causes a motorcycle to have intermittent spark?
When there is fuel and air in your cylinder and the spark plug doesn’t ignite it, it gets pushed out of the cylinder on the compression stroke and as soon as it hits the hot exhaust header it combusts. An intermittent spark can be caused by the spark plugs, the spark plug wires, or the ignition coil.
Why does my car keep sputtering and backfiring?
Another way this happens (too rich) is the float needle in the carb isn’t closing, so the carburetor is flooding the engine. This happens when a little bit of dirt gets stuck on the top of the float needle so it can’t close.
How to get Briggs and Stratton backfiring to work?
Thank you in advance. Try spraying a 2 second burst of spray carb cleaner into the carb throat and then see if it will start and run for about 2 seconds before dying. The symptoms you have described sound like it is not getting sufficient fuel from the carb.
What causes a backfire on an unburned engine?
Unburned fuel then is allowed to pass into the exhaust system where it can backfire. The same type of problem can be caused by a worn out or damaged spark plug wire. A bad wire will make the spark’s travel difficult, weaken the spark, or simply push it into an adjacent wire or to ground, resulting in a backfire.
Can a worn out timing belt cause a backfire?
A worn out timing belt can upset the combustion process and lead to backfires. Gasoline engines need to fire spark plugs on time to properly ignite the air-fuel mixture inside a cylinder. On time means that sometimes the spark needs to be fired ahead in advance or retarded depending on engine speed and load conditions.
