I did notice a very small amount of oil sitting in there though. a tiny amount, just enough to feel the slick on my finger after wiping it out. maybe 2 drops? Is this normal? could that just be from the couple times that I have forgotten to pull the wash plug before trying to start it? This is about to be a can of worms, I can feel it.

I would do a leak down test (pressure test, vacuum test) whichever you prefer to call it. That would tell you if your seal is leaking or not. Not sure if you have done this before or have the tools but here is a link to get you started. http://www.kxriders.com/forums/index.php/topic,6608.0.html Hope this helps.

No it won't discolor the oil , It sucks it into the crankcase , and there is almost a quart of oil in there , it doesn't take much case oil to foul the plug .CBX

I'm working on putting together the necessary pieces to vacuum test my motor. when testing should i test with the crank in different positions? or maybe slowly rotate the crank

I don't think it matters what position the crank is in. I've personally never done a leak down test. When I rebuild the top end I replace the crank seals as well. Keeps the down time to a minimum so I have more seat time.

you have to block off the exhaust and intake to get the leak down to work . most leak down tools for this hook up to the intake side.it does not matteras the leak down will bypass the rings . now if your head gasket is leakin yo find that out too. this test is for your main seals mainly.hope this helps
