    The barrel will keep going for easily 17k more miles.



    What you need to be thinking about is your rings. Have you ever changed them?

    I thought i replyed to this. Hmm.



    They should need to be changed yet but without a compression tester it's a bit hard to work out if they should be changed.

    first thing you notice with worn rings is its hard to start off electric even tho it turns over fine.

    you should see a slight increase in the amount of smoke but only if you check normally anyway

    can't you check compression by covering up the exhaust and seeing if it cuts out?!



    So if it doesnt cut out you have bad compression and if it does your ok.

    no, that so called "test" is only to see if your exhaust is blowing.. i recomend you never cover the pipe as it throws pressure back towards the engine and can do damage

    No. that "checks" exhaust sealing/back pressure just as minor beat me to it and correctly stated it fucks about with the shockwave effect, not good.



    a quick compression check is to whip the spark plug out, keep the throttle open and then kick the motor over keeping your thumb over the plug hole. If its blown off or a loud pop occurs compression is ok to run generally. If there is no pop or pressure coming out you are either doing it wrong or your seals/reeds etc need replacing.



    If your handier with the tools whip the variator out and look for oil weeping from the bottom of the crankseal.

    ive found an engine will "fart" on your thumb at anything as low as 10psi so you wont really notice any dropped pressure this way till its totally fucked :nerd:

    just go get a tester, there fairly cheap, wind into the plug hole and tells you exactly what the pressure is.



    150 is good but anything above 120 is usually fine

    O right, it was just what I had been told Minor, I don't like doing it and I only have once.



    My mates at school did it to each other and it used to piss me off when they tried it as I had a feeling it doesn't do any good.



    :eh:
