Sloper S30-13 compression test

[Gadorey]

Hi everyone,

Has anybody ever done a compression test on their 500cc OHV Sloper or on a similar 500cc BSA engine?  If so what values did you get.

I just tested my own Sloper and got 106psi with a warm engine, which sounds about right, but would like to have a comparison as reference.

Cheers,
Gui
