    Ever notice you rarely see an engine for sale that is described as "seized up tight sometime long before the last time I tried to ride it"?
    Glad you got a refund...

    Yeah I guess so, it came from a breakers who said it was turning over when they stripped the bike but had to drain fluids to store, which was 3 months before I bought it. I can't get the head off at the moment because of the way the cam shafts are positioned I can't get to the bolts to release the sprockets. I've tried removing the tensioner and slipping the chain, but can't rotate the cams or get the chain off.Unless there's another way I'm missing?

    Separate the chain..... Get a chain breaking tool, or, if you don't care about the chain then just cut it.

    Thought about that. It'll mean an engine rebuild right?

    If you cut the chain, yes. If you use a chain breaker, no. The breaking tool pushes the rivet out. Tie a string to the chain. Pull the chain through, the string will be used to pull a new chain through.... Or him the new chain to the old chain. The tool also installs the new rivet.

    BUT, if you have a chain with high miles or unknown miles, why not just put a new one in anyway?

    Last question.... If you're talking about the new engine you got- you're gonna do a rebuild of a seized engine anyway, right? Put a new chain in.

    Yeah the new engine. The seizure is in in the barrels I was hoping not to have to replace to much, I'm expecting to have to change the barrels. I've got a chain breaker/riveter so will look into replacing the chain as well.

    If you can get Acetone there, use it and an equal amount of Automatic Transmission Fluid. That is the best penetrating oil ever devised.
    Heat can be your friend here too. Heat the barrels with a torch, allow the engine to cool, and repeat the process several times to help break the rust up.
