Why does the exhaust pop when you run a lean engine?
Taking out air restricion makes for a leaner running engine. The reason for the popping is that the lean flame burns longer thus going out the exhaust (I could be wrong on this)
How can you tell if a motorcycle engine is running lean?
The engine isn’t receiving enough fuel to make the motorcycle run efficiently. You’ll also notice that if an engine is running lean, the engine and exhaust pipes will become very hot, even hotter than normal.
Can a carbureted motorcycle run lean or rich?
When we talk about motorbikes with carbureted engine there are two conditions that can be possible at any given point of time- the bike’s engine is either running Lean or it is running Rich. Since the engines with the fueling through Carburetors can be tuned manually we can always alter the condition by tuning the carburetor.
Why is my exhaust plug reading rich on my bike?
It may have already pulled away from the boot and caused a weak fire issue in cylinder 4 cause the plug was reading rich and cylinders 1 , 2 & 3 were light brown which is good. So there was a little problem

What happens when you change the exhaust pipe on a motorcycle?
The stock muffler that comes on a motorcycle is designed specifically to ensure the complete and proper operation of the engine. When an exhaust pipe is changed, this causes an unbalanced air-to-fuel ratio. The airflow into the motorcycle is increased because of the difference in pipe design and other specifics.
What’s the difference between a lean and a rich engine?
A lean engine means there’s too much air and not enough fuel whereas running rich means there’s too much fuel and not enough air. The biggest difference between the two is that running rich isn’t near as detrimental for your motorcycle as it is to run it lean.
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.
