I just got done working on my bike today, I did a oil change, spark plugs, manual cct install, and check my air filter. My first concern was when we pulled out the spark plugs they all seemed to have oil on them but I think the guy before tightened them too tight, but is this a big problem? Second my air filter was drenched in gas. Lastly I think, not sure, but I think I smelt a little gas in my oil, but I'm not tottaly possitive. I also now need a new air filter, what kind should I get?

Thats a big question i've always wondered what would be a good kind from a riders prospective...they could just be all the same but im not quite sure.

When I get my bike all put back together I'll post some more pictures of it, and maybe video showing off it's D&D exaust. Just need to buy a few parts and get some free time in order to do so but I'm not in too much of a hurry since the roads are snow covered at the moment.

yeah thats a real good price for a K&N but from what i understand for our bikes its best to use a paper filter. i use paper but can not tell you K&N will be better or worse just what i read on here.

K&Ns are only beneficial if you have had a signifigant amount of engine hop-ups done (2mm over,good headwork,cams).If you have all 3 listed done,a K&N will help.Otherwise,paper is best.EMGO sells them for 25 bucks,and they are close enough to OEM.I learned this the hard way:time,energy,work and wallet.

My old air filter is odd its like a foam filter with a mesh screen, but should I be worried buying a paper filter if I end up still getting a little gas in my airbox?

K&N is good even without hop ups, but while letting in mor air, it does let in more dirt. Plenty of testing out there that shows that. As far as I'm concerned, with the recommended oil change and detergent gas we use today, not really a big deal.
As far as the plugs go, where was the oil on the plugs? If it was around the top of the threads and the tips were clean and not oily black, I wouldn't worry. If only oily around te top of the threads, the valve cover gasket could be leaking a slight touch. If the tip is oily or if an oil buildup is on the tip, you could have worn rings, or bad/worn valve stem seals. Either of these two things could also explain the gas in the oil. I would be doing a compression check ASAP so you'll know what you are getting into before riding season. if the air filter was drenched in gas, you have problems. The air filter normally gets some recirculated crank case gasses. I also suppose that a bad intake valve (hanging valve) could allow fuel to come back through the carb opening into the airbox.
You sure it's just not wet with a gasoline smell? it's normal for air filters that have been used quite a bit to smell like gas.

On the tips of the spark plugs it was black colored almost dry carbonized look but on the threads their was dark black oil. For the air filter I'll check it soon but I'm pretty sure it was gas because the whole air box had a sticky feel as if it was old gas.

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 knob the makes it run richer or leaner so I havent bothered touching it.
