So there it happened, the rear bottom oil drain screw is missing.. so is the engine oil.. I noticed a very noisy engine when i got home, and saw oil drips under the bike after few seconds..
I could have gotten lucky, but i dont take any chances...
Guess i will take out the engine, and try to open it and change out bearings, rings and look for other damages now..
Life sucks sometimes.. Allthoug, life was great only seconds before

Ripped off the head, and cylinder now, and found the piston in a bad shape..
The camshafts are ok, and they had plenty of oil film on them..
The piston`s rear side, has heat damage, so the rings are stuck there..
The cylinder has marks after the heat of the piston, but it feels like it`s something stuck in there if you know what i mean.. Seems like the piston metal has melted on the nicalsil cyl or something.. I`ll try to "hone" (is that a word for cylinder "grinding/polishing" in english? ) the cylinder to see if i get it out..
But a much more important question:
The cranck is a little blue on both sides of the rod. Is this normal?
I can feel a little slack sideways (from left to right, not twisting) but can not say that i feel anything up/down..
Is there hope for not splitting the engine, or is it just a stupid thought not to?

I've always drilled & safety wired my drain plugs as well as the oil filter screws. Indy's advice is sound.
to do this do you just drill a small hole through the head of the bolt and then safety wire it to where? just want to make sure this doesn't happen to me and burn the piston.

now is the perfect time for the 490 kin in your SM bike .

I ordered a standard size wiseco piston today, so i will try this out first..
If the engine still makes alot of noise, i will pull it out of the bike, and do a full makeover.. Perhaps i build it up again with a ported head and big bore then.. But for now i`ll just stick with original ccm and my hotcams+ setup from before..
If this goes well, then my cristmas is saved A full week free from work, without my bike running, could be boooring...
