    Hi,
    I got lucky and found a muffler on ebay for my '89B 510TE.
    There was nothing inside it except for some nuts actually.. So it's popular with some rodent too apparently.

    Anyone got an idea of what the innards of it would've looked like when stock?
    I'm guessing a perforated steel tube with fibre glass wrapping but was it like that for the full length or was there some kind of baffle too?
    The parts manual seems to show a full length tube with fibre glass.

    I would want it to be rather quiet and I presume a stock 1989 TE-model was that.
    Pics show front and rear caps, can you tell if the end caps are stock?

    If you know diameter or other dimensions of the perforated steel tube please let me know. Thanks!

    I've found out what the baffle looks like now. These are from a 510TE 89A model.

    They came with this bike that I bought yesterday - a 1989 510TE with only 918 kilometres on the clock and one previous owner.

    Very cool and well kept bike. I prefer the suspension on the A model, my B model got a shock change over to Ohlins.
    They must of put the 88 swingarm decal on it, like I also did too, Easier to read those ones ;)

    Thanks Steve!
    I've read there were ~400 510 89A's built in Sweden of left-overs under Cagiva management, up to frame no. 7T000400, mine is 318.
    If they were sold thru Swedish dealers they also had the SIMA-plate riveted on the headstock, like this has. The engine says "Made in Sweden" too.
    It shows that it was built from left-overs. The sub-frame is for the previous plastics and the frame still has a lug for the older style airbox.

    I have your no. 7 as an inspiration to keep on getting mine running again! ;)

    Interesting, my model B cases have the elephant logo by the drain plug.
    No SIMA plate on mine.
