    Compression tester for 250r?

    I want to get a compression tester for an 85-86 250r. I'm wondering if thishttp://www.amazon.com/INNOVA-3615-Co...ion+tester+atv is a decent one. It has not information on thread sizes. I'd hate to end up with three size options that don't fit.

    Thanks.

    The 250r has a 14mm thread. It states that the tester has a 14mm adapter. It should work.
    Remember you need to have the throttle wide open when testing.

    Hey, thanks man! I didn't know about the wide open throttle. You're awesome!
