    Afraid to ask this one.

    The book says the motor turns in a clockwise direction. BUT is that when you are sitting on the bike OR when you are looking at the front of the bike??

    Don't know which way to turn.

    The general rule on that is it is when you are looking at the front of the engine. So it depends on which way the engine is.
    Most engines turn clockwise. However, there are exceptions.

    If it's the '95 RS, turn it clockwise while looking at it from the front of the bike.
    I painted an arrow on my pulley so I could stop figuring this out every time.

    Easy to figure out starting from the rear wheel --

    Rear wheel rotation makes the final drive pinion rotate counter-clockwise, looking forward from the rear of the bike (top of pinion rotating toward rider's left, toward crown gear).

    Counter-clockwise pinion rotation means the driveshaft and tranny output shaft rotate in the same direction.

    The tranny has three shafts -- output, intermediate and input, so after the double direction-change across the intermediate shaft, the input shaft rotates the same direction as the output shaft (still counter-clockwise, looking forward).

    The crankshaft (and thus the crank pulley) rotates with the input shaft, so the crank pulley also rotates in the counter-clockwise direction, looking from the rear forward -- or standing in front of the bike, clockwise.

    Short form: On a BMW boxer, the crank pulley rotates the same direction as the final drive pinion.

    Another reason I was asking is the Haynes book showed a picture of the Timing chain behind the front cover. The gear shifter side (as you look at the front) of the chain loop had the tensioner on it. I though the tensioner alway went on the non-load/return side. If the motor turns clockwise when your facing it then the load side of the chain in under the tensioner.

    Airheads have been the same way since at least 1969 -- tensioner on the rider's left (on the right looking from the front).

    Sit on the bike and have it in neutral.
    Rev it up.
    If it is turning clockwise you will tip to the right.

    Simple answer, put the bike on the center stand, pull the cover, put the bike in neutral, and have someone hit the starter while you look at the direction of rotation.

    That is the return side. The cam drive sprocket is below the crank sprocket. The crank pulls up on the chain to the oil pump / cam drive shaft on rider's right and pushes the slack to rider's left, where the tensioner is.
