4 Stroke vs. 2 Stroke Maintenance
 

I know that 4 stroke engines are a little more complicated than 2 strokes. How does this translate into maintenance requirements....does the 4 stroke need more TLC and if so...what would that be?

Thanks in advance.

The four strokes have the valves that should be looked after.

What I'm seeing is that a lot of people are not looking after them and the will have something damaged about the valve train after several years use. They will drop a valve or have extensive wear about the cam and lifters. These problems appear to be from excessive valve clearance in the engines I have repaired.

Enjoy,

It's not that much different. A valve adjustment from time to time (not everyday), and a good bit of oil at the end of the flying session and you're in good shape.

Skip the oil, and you can join in the masses posting things like "my bearings are all rusty". <GGGG>


4Cs are fun. Enjoy yours.

I've never, after many years of both 4 stroke and 2 stroke use, noticed any significant difference between 2 and 4 stroke maintenance. One wears out con rods and pistons and the other valves.
However, the 4 strokers seem to run longer than the 2 strokers to begin with, perhaps because of their natural lower rpm.
