    Default Is there a big bore kit available for Honda CG125? Like 180+ cc's?

    The other day, I was at a 'Chonda' Dealer. There was a Chinese 100 on the display among many. I asked him few question about it and he said that this 100 is basically a 'stroked-up' 70cc engine and most internal parts are interchangeable with 70cc bikes. Upon closer inspection, I confirmed his claim. The bore seemed to be the same, with a slightly longer cylinder which possibly means a taller stroke... Hence the extra 30 cubes!
    Anyhow, I was wondering if there're big bore kits available for CG125 with a bigger bore? Like 150cc plus? Thanks.

    250cc? Woah! It sounds impossible to me. You've to 'shave' or 'peel' the cylinder internals to accomodate a bigger bore. Too thin of a bore, and the whole cylinder will EXPLODE! Boom...
