jet size on aerox :)

hello,
i have a 70cc aerox
the kit is athena 70cc aluminum 1 ring
and carb is 19mm DELORTTO
the jet now is 72
and i with standard airbox

the aerox start with the airbox and if i want to drive i need
to put out the airbox if i will stay with the standard airbox and i
will put al full gas the aerox will turn off
the aerox stay on rpm with the close airbox but withot the airbox
he not

so i need anther jet? i think smaller i right?

thanks

 

Try till u get the right size...

 

id think bigger mate, with my zx pipe and standard 50 im running 68, gonna stick a size 70 in cause its not big enough i dont think

 

try popping the breather out of the top to give it more air, failing that. run a filter or just jet to run with airbox

 

u deff need a bigger jet i have a size 72 in ma aerox nd that has standard exhaust just de restricted
