Why does a 4 cylinder engine sound different?
Why does a 4 cylinder engine sound different?
Specifically, a 4-cylinder engine is going to sound different than a 6- or 8-cylinder engine. In a misfire, one or more of your engine’s cylinders may go entirely dead, and suddenly your V8 is a V7. To a trained ear, that loss of a cylinder will produce a different engine note, and it can be a sign of a severe misfire.
What does it mean when your motorcycle engine is making strange noises?
Locating the precise source of some engine noises can be tricky, but very helpful in sorting out what needs to be done. A mechanic’s stethoscope can be helpful in doing that. It works and looks much like a medical stethoscope, but with a metal probe replacing the diaphragm head.
How to tell if your motorcycle has a lean mixture?
Typical symptoms of a lean mixture are: 1 Backfiring as the throttle is closed (primarily during coast-downs) 2 Lurching acceleration 3 White or light gray spark plugs 4 Requiring excessive amounts of choke to run/start 5 White or light gray muffler end pipes 6 Bluing (on chrome systems) of the exhaust header down-pipes
What happens if you lose a cylinder in a V8?
In a V8, a loss of a cylinder still results in your engine being able to produce 87% of its capacity. However, in a 4 cylinder, a loss of a cylinder knocks your power down to 75%.
Can a MBE cylinder head be mass produced?
MBE doesn’t mass produce cylinder heads. Instead, it concentrates on producing highly efficient heads for top-level competition, and the result is precision far beyond what you will find anywhere else.
What are the names of the cylinder heads?

What are the port flow coefficients of MBE?
MBE’s port flow coefficients for these heads are unmatched in the industry: 440 cfm for the intakes and 270 exhausts—and remember, MBE is the only cylinder head specialist that guarantees its published port flow numbers. These heads are especially popular in nitrous and naturally aspirated applications.
How big is a 13 degree MBE head?
For example, in order to match more engine packages, MBE has designed three distinct port profiles for the 13 degree MBE head, and the largest works with engines up to 450 cubic inches.
