    Yamaha 1.8 SHO 2013. Compression Specs

    Hi guys
    Im doin a compression test on my Yamaha 1.8 sho engine.

    I cant find the specs. What should the compression be on this engine?

    I guess its the same on all yamaha sho 1.8 but i cant find it.

    Why you doing compression checks? Routine maintenance or you have a problem?
