i'm fairly sure it's the same as the one in the early link "crank link" bbecause it is 1.5kg lighter than standard weight. or maybe iv'e just been thrown off by the head and carbies?
it has standard stroke because we built it with standard pistons, rods etc. also the race head has had 255 thou off with only small reliefs in the pistons and the cam has 515 thou lift and nothing crashed.
i should clarify as well this engine is a later engine (middle dizzy) so if it is a gx then it is a b210 gx, it is definatlley not a an a14. so it has-gx style closed chamber head -with the double springs -flat top hitachis -twin outlet exhaust manifold -this lighten crank i speak of it was given to me ages ago so i have no idea of its origin. anyone else got a clue??
thanks Fandatstick its looks like it could be it im going to go out and do a comparison. i did say this engine was supose to be a gx1200 but im starting to wonder, the hitachis are square top as well and after reading wiki thats not gx1200? i wonder if the head with heart shape chambers and same double valve springs as gx1200 is actually off something else? with this crank as well that makes this engine what?-ta
