    Steven, do you have the Riva valve train upgrade tool kit?

    I took the hose from the kit, screwed a schrader valve in the 12mm end, and attached the hose to my compression gauge... works slick!

    Just don't forget to remove the schrader valve or you may drop a valve on your next upgrade... don't ask me how I know.

    Make sure you do a warm motor or the test could be all over the place.

    how warm?
    can the engine be warmed up on hose for a few seconds or does it need to have been run in the water?

    compression

    remember to hold the throttle wide open while cranking the engine over.
