Plug Chop Pics


Recommended Posts

too lean? :shootself: .......throw a set of new plugs in and do a wot 1-6 run! kill it and pull in clutch. those plugs look like they have alot of hrs on them... also wack the plug threads off at the base so you can see whats going on better.

Them plugs had about 10 minutes of ride time on them.

 

I put them in, let it idle, rode it a bit to warm up the motor, then did WOT run and killed it and pulled them.

 

How far down am i supposed to cut them? All the way at the bottom of the washer?

I haven't done a chop for years, when you can do it by seat of the pants, feel and knowledge, its better and faster and you don't waist plugs and time.

 

YOU CAN DO IT!!!! nana2.gif

your waaay fat. I would drop 3-4 mains

 

 

Am i focusing too much on the electrode colors?

 

I know what to look for in the plug chop, but does it mean a pinch of shit how the electrode tip looks or is it just how the smoke ring looks and measures?

 

thanks for all the help fellas, i appreciate it. Im new to this but not new to quads.....jetting is a new battle for me but im catching onto it.

if your only doing short wide open bursts like motox track you can get away with lean jetting on the ragged edge. running pinned for 600' you probly want the brown ring alittle higher up the porcelin. 1/3 to 1/2 way up. im no carb expert but i run 600' and it dont take long to ruin a engine if you get caught with your pants down

The ideal Soot ring thickness for WOT jetting is the thickness of a dime. "Light light bown as thick as a dime" is darn close to perfect.

according to some tuning books the ideal ring for maximum power is about 1/2 - 2/3 thickness of a dime. basically just a whiff of brown. most people ride for fun and dont need to be a hero running their stuff at the extreme. racing for a million bucks or pink slips it would be a different story. not sure about anybody else but i already burned down one piston this year and thats one too many

The way to really tell for MAXIMUM power, so to run on a dyno, and put a exhaust bung in that reads Air/fuel ratio. Keep leaning it out until the power starts to drop off. Then you know your perfect. USually peak power is around 13:1-14.5:1 Depending on the engine. Every engine is alittle bit different. I will agree "Peak" power on a spark plug soot ring will be less then a dimes thickness. But if you go with a dime thickness its safe and its close to perfect.
