excellant man now can u tell us what u did with it?
what head and cylinder u installed?
also the lack of air filter is bound to cause a very premature engine failure,, u will get ur bike seized very soon,
what was the reason for not installing air filter? i think the opeing of carb where air filter lota goes is very large then the pipe,, so u left it just uncovered? i also face the same issue,,thats y i bought another carb that has small opening,,
also u seem to be using the cg 125 carb its venturi is 26mm and the inlet pipe (the one which connects the carb to head) is that of cd 70 ,, its 20mm Internal dia, so u r not taking fu;l potential of the carb,, if u install a wider pipe then u will get a lot in terms of top speed
any other mods,, i m also modding my bike have few questions plz have a look over there as well,,
