    Nitrous oxide?

    hey mate your choke is exactly that a choke its chokes the carby but still lets the fuel in thus starving your motor of air but flooding your cylinder.. so bad idea as you need wide open throttle for nos mostly... NOS (brand name) N2O expandes the oxygen particels surounding it when realeased...

    125cc, China Mikuni jetting and porting

    hey i recently ported my head.. just cleand it up and a little bit of shaping very minor... now i put it back together and it starts and runs great untill about just over half way thru the rev range and it stutter really bad...i can hear how lean it is.. i'm thinking this is due to jetting...

    Front suspension

    just pack it up with washers... works a treat if you dont want to spend any money... i got about eight in each side,handles much better... but do it to suit your weight and the way you like it....

    Engine options,

    a 80 is smaller in size then your 125! and if you find an old air cooled one its a breeze... but i would prefer to go with a watercooled which i will when my ducar dies but it just aint... i might choose the KTM 65 because its a screamer but an 80 just sounds better... look on a few american...

    Engine options,

    drop a cr80 2 stroker in it with the box fits fairly easy if ya handy with a welder.... just make sure you can hold on... that could be done fairly cheap to. alot cheaper then putting a crf50 modded motor or stock that matter in...

    Stock Muffler Fun

    by no exhaust do you mean no end can? because if you have NO exhuast you will burn out your exhaust valve... p.s i thought a JR50 was 2 stroke so no end can would make less power more noise.
