When doing plug chops you new to read the band at the bottom of the porcelain insulator. For this you need a new plug. Just looking at a plug will let you know if it's running ok but beware as each oil and gas type will leave your plug looking different each time. An oil like yamalube will give a black sooty plug but as long as the tip of the electrode is clean it's running fine. Amsoil will leave you with a clear caramel colored almost reddish looking plug. This is why they tell you to read the bands.

I am like V in using a used plug. I have trouble seeing very much with a new one and getting one into the ball park and spending plugs to do it didn't seem wise to me. When you get down to really trying to determine your jetting for maximum power in full throttle situations though, one of those little magnifiers that come with it's own light and a box of plugs should be in the bag you carry, I think.

I also think that most of us can take a look at a plug that is taken out of a bike and know if the jetting is very far off or if the bike and or heat range is wrong for the type of riding.

Let's face it. Guys like us don't do plug chops anymore. We just look at the plug "just in case". We know when we start the bike how it's going to run that day and just adjust accordingly...:thumb:

It can be a really long day to get one down to the proverbial "hair" it isnt as much fun as it sounds like either.

Can anyone tell me where the airscrew is on this carb. My bike hasn't fouled and plugs and there isn't any oil coming out of the exhaust. But when I rev my bike up while it's idling it seems to bog. Even when I'm just putting and then I want to give it has. It bogs for a few seconds and then it kicks in. I'm thinking it has to do with the pilot jet but I have no clue where the air screw is at.

Right side of the fuel line between the intake boot and carb bowel.
