Cleaning the motor.

[OrangeBrian]

It seems to me that my motor has carbon build up on the head of my piston. what can i do the clean it up also is it worth fully ripping the motor apart to clean it and regrease it?

I use a abrasive disc on a grinding machine, it works fine!

How much carbon? They all are going to carbon up some. If its running good why try to fix it? You might break it.
I'd leave it alone keep the out side clean so when you do have to tear into it you don't get quite as dirty.
