I just had to overhaul my engine because of this. It is indeed valve stem oil seals. My valves were leaking oil so bad it was fouling the plugs on a daily basis.

Pull the head, take it to a good machine shop (like whatever one the local bike dealers farm their head work out to) and set it on the guy's desk and say:

"FIX, PLEASE!"

They know exactly how to do it all.

thanks for the reply. people told me valve steams is a possibility but i didnt notice that the valves were wet until today. i was only going off how it ran. so my memory is not short, i just explained exactly what i found today to give me that added sense of security knowing that this is truely the problem.

The valve stem oil seals are there to control the amount of oil to the valve guides. If the guides are worn, you can get oiling issues similar to bad seals Since I don't have any info on your bike, just wanted to toss that out. To swap the valve stem oil seals which ARE likely the cause of the issue (would still check for play in the guides), you need a valve spring compressor. You compress the valve assembly and remove the split keepers and then just pull the parts out. The valve stem oil seal then slips onto the end of the guide. It isn't hard to do. In your case, if your cylinder head has been getting a lot of oil, you would do will to clean the combustion chambers (wire wheel disk - fine and/or brass is best) and lap in the valves after re-assembling them into the head. It is best to keep all parts from a specific valve well together because you won't have to re-shim when you reassemble.
