    crf 250 r . head blowing?

    by merky369 » Fri Dec 14, 2018 8:10 am

    firstly . hi guys and glad to join the forum.

    right.. i have just rebiult my 250 r after big end dropped out on me.
    everything fresh from the ground
    started up no problem from a bump and sounds and runs well.

    anyway to the problem, as soon as i applied revs i heard a loud cracking sound as if the exhaust was blowing...
    so i went to look a the side whilst my friend applied the revs and its blowing straight out the side of the cylinder head gap right side of the bore. ...

    anyone else heard of this? brand new headgasket kit was fitted.

    do the head or bore need to be skimmed when applying new gasket?

    any help will be greatly appreciated . i need to get back on the track !!

    thanks for reading
