Good idea ojstinson, I'll see if I can find one of those around here.

It's not that the oil level was higher, I think it might have been like that since I changed the oil. I have taken my carbs apart to clean, I also took a look at the floats when I did this and they appeared to be fine.

I have been reading a little more and am starting to suspect the valves. I bought this bike recently, in April, and when I got it the bike had 12,600ish miles. I don't think the PO ever did a valve adjustment. The reason I say this is because when I did the first oil change the oil was really dirty, so I don't think maintenance was on the priorities list for this person. Heck, the bike had bent handle bars and the owner said he couldn't tell. I got a good deal for it that's why I went for it. Anyway, right now the bike has around 13,000 miles and I am waiting for a metric feeler gauge to check the valves.

This is what made me suspect the valves. This is in regards to different engine but still an air-cooled engine. It seems like the info would still apply here.
"A tight exhaust valve, for example, will never completely close and will let partially unburned fuel escape into the exhaust system, which in turn gets extremely hot. Moreover the loss of compression in that cylinder translates into loss of power, hence requires more work from the other 3 cylinders to keep up initial speed. "
