hi

yesterday i saw qinqgi 100 .. i tried to observe it and to my surprise it had the same cylinder head as other 70's have .. it was E22..
the cylinder was 97 cm3.. and the crankcase also seemed to be the same as other 70s... rest body etc was same except the fuel tank was a bit bigger...

so my question is that is it just 70 with few more components ?
any more info regarding this ?
i wonder when people go for engine overhaul y they stick with the default cylinder size and head etc.. y they dont go for E22 head and 97 cm cylinder so as to get a 100cc... i think 100cc just 70cc on steroids..?

what u guys think ?
