Carburetor running lean?

[wordslinger]

...Agility 50...I'm Installing a K & N air filter...

..may need to re-jet my carb, but that's OK..


Comment:  Make sure you don't run it lean!


Question: ..how can I tell if I'm running lean?


Comment: Burnt (hole in a) piston. 


Question: ..Is there any other way to determine if my carburetor is running lean, other than burning a hole in my piston?

..I'd surely like to catch that before the burn...

Hey!
I am being quoted here! 

Too much air will burn away white insulation around central electrode and corrode the main electrode too.

Also if your exhaust pipe is white-ish inside instead of black, it could be a sign it is running lean.

Finally, do not check that until engine is warmed up because cold engines usually run lean as more air is getting inside due to choke action.

p.s. Here we have probes at technical inspection station they shove up your scooter's/car's ass and measure exhaust for CO, CO2, NO2, SO2 etc... if you know somebody there you could try asking them to help you...
