Is my Harley running rich or lean?
Running to lean, the bike will run hot, spit out the air cleaner and so on. Running rich, the bike will break up down low if the pilot jet is rich, will smell, and might get some black smoke out the exhaust, to rich up top the bike will really lack top end.
Is running lean worse than rich?
Running lean can give you more power but to lean will blow your engine. Running too rich can also hurt your motor. Think of it when you are mixing gas for your weed wacker. It is always safe to add a little more oil than not enough to the mixture.
How can you tell if a motorcycle is running well or lean?
A motorcycle running well will have a little bit of wear on the end of the spark plug. A motorcycle running lean will have little or no wear on the spark plug because it’s not igniting near as much fuel as it should be. When a motorcycle runs leans, the likely culprit is the fuel delivery system.
What does lean mean on a motorcycle engine?
The perfect ratio of gas to air that a motorcycle should be receiving is 14.7 parts air to 1 parts gas or 14.7:1. If you have more than 14.7 parts air, then your motorcycle engine will run lean, meaning the engine is getting more air than it needs and is not getting enough fuel.
Can a motorcycle overheat when it is running lean?
It is possible for your engine to overheat while it’s running lean because the air and fuel mixture is burning at a higher temperature. If you have a temperature gauge, look at it closely while you’re taking a normal ride down the road and you suspect a lean issue.

Is there such a thing as a lean running engine?
Lean codes and lean-running conditions are a widespread problem that you’ll likely see again and again, on all makes and models. Year after year, state inspection/maintenance (I/M) administrators across the country report P0171 as one of the top ten DTCs that are set.
What happens if you mix oxyacetylene with lean running engine?
The composition and relative abundance of other exhaust gases changes as well. Your experience with an oxyacetylene cutting torch is a good analogy. Too lean a mixture will result in popping or a misfire; too rich a mix produces sooty smoke and a flame that won’t cut. For proper torch operation, you need a proper mixture.
