    XT500 Now those are sure popular and seem to be high in value. They sell fast.

    That's a very cool bike! The cylinder head was prone to cracking. Since you're going into the engine, acquire a 1976 to 1979 cylinder head. I believe it's a direct swap. It has a 180 degree crank. I believe they lend themselves well to cafe touches.

    Too bad most of the links in that wiki are broke. Could have made for some interesting reading. One link did work though. I threw it into the Road Test thread.
    Apparently, the demise of the 500 and 750 was the 650's salvation.

    Another link from that wiki.
    Looks like 78 was the Crème de la crème of the 500's. With all the bugs sorted out, it was finally a solid bike. Unfortunately it was too little too late.

    The original silencers were long gone when I got the bike. I experimented with several types, eventually fitted these, they are Triumph T140.

    Lakeview has had really good luck with H-D Sportster mufflers which are very commonly available at swap meets as the Harley crowd like noise. The Sportster mufflers fit the XS650 well and sound good plus, H-D chrome is very durable and nice.

    There is no doubt that the TX500/750 were overly complicated and didn’t have a great reputation, but as an engineering tour de force, they showed what Yamaha could do. We can only wonder what impression the four cylinder two stroke road bike would have made.

    Yes, seen it :geek:
    But just look at those long shiny T140 mufflers. Almost original looking.
    :cool:

    It would have been a mistake to pass it up at that price.

    Also on a plus side as far as I’m concerned, they are quiet, noisy exhausts just drive me nuts these days.
    I’m wondering if the Tinnitus I have is from a misspent youth riding around with open meggas.

    I think it's still a good bike. A cracking head? That seems a little far-fetched even if it's happened before. How often does it really happen?

    Could that be why this engine is stuck, because of a cracked head?

    I concur. As I recall it, the head cracking problem was related to the design of the head casting and any overheating or improper torquing could make it more likely.

    The “seizing” is most likely just gummy crap sticking the rings to the cylinder walls. More often than not, it can be unstuck by pouring a bit of lubricant down the spark plug holes and letting it sit - and then putting a wrench on the crankshaft nut (usually on the alternator end) and gently working it back and forth.

    NOTE: do not stomp on the kick start lever. That seldom breaks loose an engine but it can cause serious internal damage.

    Maybe an "exploded view" of an TX500 engine posted would be beneficial.
    Cafetools, how many miles are on that. I cant quite make out the odometer reading ?
    And do you have the title?
