    ALL

    Last summer noticed misaligned chain....realigned w/swing arm marks & stored for winter (w/out using any alignment tool)
    Previous owner install new chains&sprockects
    Is there anyway to install a countershaft sprocket backwards....?...therefore misaligning front & rear sprockets...

    next issue.....Hi speed wobble @105mph.....read many threads on wobble & chain misalignment....possible relationship...?

    Just purchased simple metal alignment tool & gonna align to get sprockets straight ....then measure pivot point to axial....go from there.....thoughts.???...Thank you

    Perhaps you can also check the front / rear wheel alignment,  simply lay a straight edge (floor board or similar) on the floor with one side against the rear tyre, measure the distance from the edge of the board to the front tyre and repeat on the other side, the distances should be the same

    To properly align wheels and chain, you have to go through the following procedure once to ascertain your problem area.  :028:

    -----------------------------------------------------------------

    Wheel alignment should be checked first & any issues resolved, this gives you a solid & correct base for sorting out your chain alignment  :028:

    Firstly, with the chain slack, measure from the swing arm pivot to the rear wheel spindle on each side and make them equal.
    That will prove if the alignment marks are correct or not.  :028:
    (You only have to do this once unless you take the swingarm out for some reason).

    Then you should find, using the plank or string method, that your front and rear wheels align.  :028:
    If not then you have a twisted frame / forks.  :138:



    Then adjust the chain slack to the recommended measurement.  :028:

    If the above is ok, but then you now find the chain / sprocket do not line up (using a tool such as the promotion tool), this indicates that you have a twisted sprocket alignment or a transverse sprocket misalignment.



    A twisted sprocket alignment means that the engine is twisted in the frame. :33:
    This can be solved by shimming the engine at its mounting points.
    (Usually occurs if you have disturbed the engine mounting points at any time by having the engine out or even when crashbars are fitted and the wrong engine to frame mounting bolt tightening sequence is not followed :whistle:)

    A transverse sprocket misalignment means that the sprockets are running parallel to but not in alignment. :003:
    This can be solved by using shims at the rear or front sprockets to align them properly. :152:

    I used to do this with my British bikes and I found it much easier to do if I put a couple of bricks under the plank rather than have it on the floor. It's reall a two-man job because, I think, it's best if the bike is on its wheels but then it's a two-minute job to do the check.

    Also, make sure the front wheel weights are in the right place.
