    1980 XJ 650. Will start and run. After shutting down and trying to restart the engine hangs up and will not rotate. Hangs up at TDC.

    Stop running it.

    Pull valve cover; check cam timing and valve clearances.

    Do a compression test.

    So, it hangs up when it is hot, but it will crank and run when cold? TDC on the same cylinder each time, or TDC on any cylinder? When running, does it finally stop on its on or will it run indefinitely? The next time it hangs up, remove the plugs and see if it will turn over.

    Sorry for the long delay on response but been busy. Pulled head 2&3 intake valves bent. Must be valve timing. Cannot get dots to line up. Intake cam appears to be 1/2 of a tooth off. That's might tight clearance if half a tooth makes a difference but I guess I've got a stretched chain.
