I've just picked up my bike from the mech after the bike stopped on me, after I stopped at the lights, it started again but only after a few minutes of kicking it over then it flew, so the mech has looked it over and took the carb apart and cleaned it up and has discovered that the Jets are aftermarket and are not performing correctly (old), i.e. they're spraying an oval not a circle, so they may be causing the bike to stall/stop after riding for a short period, his suggestion was to replace the carbie with another one from a 99 ZX-9R to go back to the standard Jets.
My Question to all with more knowledge than me, do I need to get another carbie altogether with the standard jets in it or am I able to get some Jets to replace whats in there now, are they able to be removed?
