    Your latest photos confirm what we thought, someone stuffed up. Follow Muddy Sump's video carefully and you will get your bike running as it should and have peace of mind as a bonus!
    Laterally unstable unless moving.

    I don't think the timing chain can jump a tooth when the engine is fully assembled and must have happened after someone had removed the tensioner, for example - perhaps it had developed a rattle and someone took it off to service and then rotated the engine with it removed causing the chain to jump a tooth :084:

    Unfortunately, you will need to remove the tensioner and the top chain guide to give you enough slack to be able to lift the chain off the inlet camshaft sprocket to allow it to be rotated. What I don't know is whether the inlet camshaft will stay in place when you remove the chain tension and how easy it will be to rotate it - that will depend on the force being exerted on the camshaft by any open inlet valve. Worst case, you may have to take off the camshafts and properly align the chain during reassembly.

    I should have added that it is best to lock the crankshaft after removing the side cover to make sure the engine does not rotate when you try to adjust the timing chain alignment :084:
