Airsal 80ccm cylinder for 139sqm


Today I found some time to measure the compression ratio of the Airsal 80cc cylinder for 139 square meters. I was really amazed! With an original 50ccm cylinder head (Euro2, combustion chamber volume 4,8ccm), the Airsal has a compression ratio of fabulous 15,5: 1 (!!!). I was excited about the test run.

I was not disappointed: here the P4 barrel with the 139 square meter engine, dethrottled original vario and ignition, otherwise unchanged.

[inspic = 79, left, fullscreen, thumb] Already pretty good for the fact that the cylinder runs with the original cylinder head. Comparable “online auction bargains” only manage their 4PS on average ...
