based on that above principle i have an idea i thaught of sharing it......
as i might never do it
acha doosri cheez when i was in malaysia kl many boys wer using small small bikes mostly 50 cc and the small junior trails and they were very enthusiastic about it.
driving very roughly like some of our khi wild boys hehe i loved it.
any way what i learnt is
it is a new technique
keep your bike as low as possible and as light as possible.
how to keep it light
suggestion
(1) take a 70cc frame strip it off every thing just keep the front fork and handle bar along with tyres brakes and clutch and necesary items.
baki sab nikaal do.......put a single very light seat
basicly dont keep any thing which is un nesasary( dont care if bike looks ugly) just no extra parts
only purpose parts aur jo parts hai bi us ko bi lite kero use ....carbon fibre (metophoricly:D)
(2) step is install the heaviest engine possible id recomend atleast cb 180 (Saleem zindabad:P) or if u cant manage 180, then a CB 125 bore stroked to 150.
that will be addaquate power
(3) rd step will be to lower the bike as mush as possible
engine body should be just hi enuf not to touch the ground.
(4) th step is skim the bike from top and get it as low as posible reduce handle height reduce seat height reduce back joint height.
(5) step u will have to chop the bike from the middle and , make a sitting area, basicly u will be sitting in the middle of the bike with only ur head coming out. and also shortent the bike as mush as possible
(6) step obviously with all the above u will not be able to sit straight u will littrely have to lie on the bike legs back and hands forward almost 180 degrees.
now how to do that is on you i have given the idea if any one follows i will help out further
