    Source for BBK headgaskets

    Alright, when installing my BBK yesterday I had a ponderance. If i did want to pull my head off for some reason (put a modded head etc on) where would i go to about getting a new headgasket? I have a kitaco 164cc bbk (60mm bore), I probably couldnt get away with using a stock headgasket as there would be extra junk in the combustion chamber at that point.

    And from the looks of it i cant find just a kitaco 60mm bore headgasket.

    The 170ccs come with the stock head gasket (or similarly sized). On mine there were just 2 small burn marks with it near the exhaust valves. It barely gets into the combustion chamber.
    Finbro and Takegawa might have their own gaskets (or maybe finbro uses takegawas).

    Oh really, well then, for my 164 ( which is 1mm less diameter than the 170's ) stock head gasket should work fine then, I like that!

    if any hangs into the chamber unsupported it will get really hot and can cause pre-detonation (as the hot 'sliver' of head gasket in there can ignite the fuel too early) . be careful on this.

    Kitaco has 3 different part numbers for the 133, 164 and 181 BBK head gaskets, you should be able to find it back on your detailed packing list.
    133 ø54mm 961-1432300
    164 ø60mm 961-1432310
    181 ø63mm 961-1432320

    Nevermind, i lied. The one i measured was from the Koso 170 kit. I just got my stock cylinder back out and the head gasket is definitely the exact same size as the bore.
