You tend to get gunk up inside the airbox because of the circulation with the crank case. There is a sub-filter (small black box on the right side of the airbox) that is supposed to filter most of this out.

Check if it's still there, and if it is, check the condition of the filter inside.

If you spark plug tips are black and dry, it sounds like you're running too rich, which could further lead to the smell of gasoline and wet plugs.

So could me running rich be connected to both the problems, If the filter is bad or not there. AAAAAAAnnndd,I'm not sure how to work the little **** the makes it run richer or leaner so I havent bothered touching it.

There's no little **** that makes it lean or rich, the jetting of the carburetor affects that as well as the air/fuel mixture screws on each carb.

Do you have an aftermarket exhaust?

I've got a D&D slip-on but the guy I bought the bike from said the little **** by the front of the rear cowling was a leaner richer kinda mechanism.

Edit: on the left side if your sitting on the bike.

The guy you bought it from was a "****"

That's the idle adjust screw... that just speeds up or slows down the engine while it's idleing, it just holds the throttle open to keep the engine running [:'(]

If your bike hasn't been re-jetted it's highly likely that it runs toolean due to the aftermarket pipe, this will give you problems in the long run... such as you are experiencing now.

Haha, at least you set me straight before I spent hours trying to figure it out. He did have a few screws loose. My spark plugs though did take a lot of effert to take off so I think that might...might be why im having a few problems.

I'd have to see the bike to determine if there's anything wrong with it...

Does it run alright?

When it was running, did you have a lot of popping and "backfire" from the exhaust?

if it was popping that's a sign of running too lean, but the wet spark plugs and gassy smell indicate a rich mixture, so I have no idea lol...

It runs fine except when you rev it she sometimes has a tad bit of a delay. But is jetting somethings I could do myself with a Clymers or more of a bike shop kind of need?

I did mine, if you know what you're doing it's not hard.

I believe the instructions that come with the dynojet kit explain most of it...
