    Shaving an engine casing?

    after a complication with a cliff, my bike has been left with scratches (about 1mm deep).

    is it possible to machine these scratches out and re-powder coat my casing?
    I asked God for a bike, but I know God doesn't work that way. So I stole a bike and asked for forgiveness.

    Bog them and then re-powdercoat/paint what ever
    Don't machine then out

    Or get a welder to fill them and sand the weld flush

    PS - photos would help with an informed answer

    The trouble is, you put it down (or is it sideways ) on a rough grade cliff. What you want to do, is find a nice bit of super smooth road/wall, or perhaps a concrete car park, and put it down in exactly the same way for a much more even surface finish

    Or see what the powder coater you plan on using recommends as a bog, metal putty type stuff might be better.

    It depends what the powdercoater prefers.

    If you bog it with a good 'reinforced' bog and spray bomb it you'd be ok. Don't worrk about doing it properly until sale time.

    Whats a new cover worth? By the time it is welded and painted ......


    Check ebay for a replacement - you may find a mint one for little $.


    Many moons back we used to take Yammy XS650's and machine/buff out the Yamaha logos from the engine covers - mind you back then they were really thick alloy.

    Beadblast then fill with a high temp filler, sand then baked enamel.

    In your shoes OP I'd simply sand the case smooth and paint it with a good heat proof paint.
