Jetting Question

So how exactly do you tell when your needle setting and main jet are just right, not too lean, not too rich?

I think I've got the pilot/fuel screw adjustment figured out.


Good question, I have pondered this also.

I believe the only EXACT way is to get the bike on the dyno and have the sensors analysing the gases.

No bike dyno's where I live so its just trial and error for the best throttle response and good old plug colour at various throttle openings.
