[140cc_OnERR]

haha soz what are the jets in the carby ?

 

[JuzzzzzY]

yeah jets control the flow of fuel to the bike

yeah jets control the amount of fuel that goes to the engine.
if you run premium fuel you should re-jet the carby a little leaner as it burns cleaner.

i dont think this is your problem tho, as a lot of people run premium on a standard tune with next to no drama's.

does the engine blow smoke? if so what colour?

show us what the spark plug looks like
