Did I mortally wound my motor? Previous tune up valve clearances set to tight.

    Why? This is 100% accurate, no mistakes, every time:

    Always looking at the right cam chain:

    [​IMG]
    See the arrow, adjust the right valves.

    [​IMG]
    See the lug, adjust the left side valves.

    This is only applicable to the 2004-2009 Hexheads.

    On the R1100/1150, the arrow can be there on either side, but to be sure you are doing the correct side, make sure both intake and exhaust have slack, and you are on the correct side. When done, rotate until the arrow comes around and ensure valve slack and do the other side.

    This is much simpler than some like to make it in philoshphical discussions.:norton

    If you look at the boxer camshaft base circle, the stick in the cylinder plug hole method for TDC (approximately) determination works fine.

    If you have changed the camshafts, all bets are off.

    Hmmmmmm.....interesting question...how many of you have changed your camshafts from stock?

    On a boxer? Few I would say. IIRC there is only one company making them, and they aren't worth the cost IMHO.

    Well it is quiet easy really if you move the crankshaft through 45 deg each side of TDC you will see the cylinder that is not on compression stroke one valve will be closing and the other will start to open these valves are on the rock adjust the other side. Its the same with all 4 stroke engines with even number of cylinders
    eg 1-6 2-5 3-4 gone are they days of setting tappets but I remember them well you dont even need to look at timing marks.
