Do carbon fiber pipe guards work?
It’s a legitimate carbon fiber product, not just fiberglass, and it’s rigid enough to offer true protection. When you place the guard on the YZ250 pipe, it’s clear that the guard is a precision fit. A hard impact can distort the pipe without making a dent. This is actually a good thing.
How does a 2 stroke pipe work?
Each time the piston uncovers the exhaust port (which is cut into the side of the cylinder in two-strokes), the pulse of exhaust gases rushing out the port creates a positive pressure wave which radiates from the exhaust port. Early two strokes had straight pipes, a simple length of tube attached to the exhaust port.
Should a 2 stroke smoke?
Since the engine is burning pre-mix oil we have to be careful here, because blueish-white smoke is a normal occurrence of two-stroke engine operation. However, excessive smoke after warm up can be an indicator of a couple problems.
Why does 2 stroke leak oil?
2 stroke engines almost always exhaust some unburnt fuel, due to the nature of the engine. “Each time a new charge of air/fuel is loaded into the combustion chamber, part of it leaks out through the exhaust port. That’s why you see a sheen of oil around any two-stroke boat motor. “
Can a 2 stroke run without expansion chamber?
2stroke doesnt need a expansion chamber to run. they can run with a straight pipe, and even with no pipe if your brave enough to do it. expansion chamber, often called a tuned pipe, greatly increases the performance.
Can you run a 2 stroke without a silencer?
2-strokes arent like 4-strokes you can actually run them with no pipes at all just a small header or whatever because there arent any valves to burn up if theres no backpressure.. the thing is that they arent going to run real great.
Why do 2 strokes have a big pipe?
On a two-stroke engine, an expansion chamber or tuned pipe is a tuned exhaust system used to enhance its power output by improving its volumetric efficiency.
