again while my motor is out I thought I'd post some decent pics of another common issue: oil leak in the front cylinder if the front of your engine is covered in oil from the exhaust down this could be why, in the pic below is the front of the motor, you see a little tube sticking out with a...

It's the smaller hole just below the crankcase vent. One on the rear cylinder also.
Pffft, oil leak? I'll show you an oil leak!
And that's just what's collected there since I degreased it two months ago.
Why haven't I mentioned this before? I guess because I also own an MGB and have gotten used to covering my garage floor with oil-dri sheets. But thanks to you Spockster and reading that old post you referenced, maybe this isn't something I have to live with.
It's kinda hard to tell if all this oil is coming from that weep hole though. There's evidence of some oil up there but the majority is around that oil filter (which I give a little snugging every so often).
Something else I learned from that old thread is why those spark plug holes are hexagonal! I had no idea they actually came off. I always thought it was a whimsical style choice on Kaw's part to shape them like that. I've seen other bikes with those deep holes that are round. I wonder how (or if) those come out?
So, is there only a weep hole on the front cyl.?
Also, will it be obvious upon removing the spark plug socket if the o-rings are responsible for my oil leak?
The parts diagram shows two o-rings in that same spot. Would I be wise to just order them both before I take the thing apart? Cheapcycleparts is no more, and the numbers in the original post don't match the ones I'm seeing on kawasakipartshouse. The 27.7mm 92055-1272 is the same but the other one lists as 92055-049 (and is described elsewhere as the 31mm o-ring used on the oil fill cap).
