    If it is oil starvation, you may find damaged rings, cylinders, valve stems & guides, rockers, bearings of rockers, cam, cam bearings, and that is just the upper end.
    If the oil starvation is bad enough it could be crank bearings, con rod & con rod bearings to include wrist pin and piston.
    You might be advised to find a used replacement engine to use while you do a complete rebuild of your original.
    Form what you say, the engine is not safe to ride at all. Find a friend with a trailer.

    The cylinder is also scarred but not bad considering how bad the piston is. The cylinder can probably be honed out and is reusable with a new piston.

    I haven't seen the cylinder but I bet a lot of what looks bad is aluminum transferred to the steel cylinder lining and that can be cleaned up and you might have a usable though less than ideal cylinder. Honing or boring to the next oversize will definitely save the cylinder.

    I have used many cylinders that others said wouldn't work but they worked fine.

    Once there if you have the tools might as well remove the cylinder head. Perhaps carefully bag and label all the nuts and bolts if you think another mechanic might finish the job eventually.
    get the kids to help, yes thats one tip i'll note down for future!

    i just managed to reach my work place, luckily in between the pouring rain as its raining season down here in Singapore, took me about an hour & half for 5km, with some pretty steep slope.

    striped the bike, would label the bolt and nuts as advice! thanks so much Fred for all the helpful tips!

    Oh, guess I didn't realize you had ridden 400 km after changing the filter...right then. If it is an issue with the filter, it would be some other issue than "that one".

    Though it is just as bad ... I just opened up my oil filter, it's the correct one with 4 holes, but the oil filter compartment is filled with gooey metal chips.

    haven't got the chance to pull the top and cylinder, but a very kind friend had brought his tool set so i can continue.

    though here's what i managed to open up yesterday:

    1/ Valve cover exhaust end (does this look like the valve is intact?)


    2/ Valve cover carb end (does this look like the valve is intact?)


    3/ Timing chain cover


    4/ Oil filter


    5/ Thick gooey metal chipped oil


    6/ Oil filter (correct one with 4 holes

    Good photos. Valve stem, keepers,spring, rocker, cam chain, chain tensioner,cam gear all look good.
    Amount of metal shaving at the oil filter does not look good.
    I believe things will not look pretty when you remove the cylinder head. Post more photos of what you find.
    But all is not lost. Now with tools we can lead through next steps. The videos and the thread r.e. base gasket repair should show the next disassembly steps.
