wide open throttle test. pull the plugs. if they are white looking youre lean. if they are tan youre very close. if they are black and oily youre too rich.. you dont need to chop the plug to get your jetting right.

do it like loco said. you don't have to cut the plug, just look at the porcelain and down inside the porcelain. actually, i've never once "chopped" a plug but I know where and how to look at the plug. an old way of doing it is to jet richer slowly until you start to get some rich sputter, then back it off a tad. thats a rough way to do it but works if your that worried.

NO NO No hold it wide open, kill it then take out the plug then look through the plug hole with a light and a lil magnifying glass and you can tell if it is lean by how big the wet spot of gas on the piston...the smaller the wet spot the leaner it is. well that s how you fine fine tune the thing

Id like to see someone look in the spark plug hole. How the hell are you gonna get your head, a light and and a magnifying glass in there to look at it? Just do a plug chop.

ive never done a plug "chop" either.. i dont really think its necessary but, hey its whatever this guy wants to do..

 

and ive sure as fuck never used a magnifying glass and looked into my cylinder through the spark plug hole! haha.

I agree, if the bike is running pretty good, a normal inspection will be fine.

That is new to me, I don't think it would be very practical to pull the front fender and gas tank out in the dunes. I suppose I could bring a flexible borescope and take a looky looky..... :ohmy: .....no, just kidding.

Ok, here is how we do it. We We use the plugs that have been in the bike and have color on them. Ride the bike around and get the engine warmed up. Then take off in about a 200 yard stretch and get it in 5th gear pineed for about 4 seconds. Kill the engine and pull in the clutch. Stop and pull the plug. If its lean, the porcelain will be really light brown/white. If its rich it will be dark brown/black with wet fuel on it. If its just right, it will be a cocoa brown color and pretty close to dry.

hahah wtf? never heard that one?

like the shee siad, how in the hell do you get your head in there, with a flashlight and magnifying glass!?!

NO...they run real good lean...for a short time.

They will run their best just before they burn up. Most people call a "plug chop" just running wide open throttle for 3 secs or so pulling in clutch, killing motor, coasting to a stop and pulling the plugs and looking at color. Grey/tan lean Chocolate brown/beer bottle color Good black or wet is rich.
