It's easy, unbolt the old one and bolt the new one in as close as you can remember and see what happens. If it doesn't work then you screwed up and have to start over. No problem. :lol:
Arrrgh. Nice one Ray! :****: :lol:
Is it best to leave the wheels on, put bike on center stand, unbolt and lower engine from the bottom?
--or--
Remove wheels, forks, place on ground and lift frame away from engine?
--or--?
Depending on your setup, as far as overhead rafters, what type of jacks you have, I'd say choice #2.
Remove front and rear assemblies, place something like a transmission jack under the motor, lift the bike off the ground from under the motor, unbolt the 9 motor mounts and lift the frame off the bike, either with elbow grease, or with comealong/ratchet straps hung from overhead rafters.
And when I say transmission jack, I mean something like this:
with a W-I-D-E support plate to really hold the motor balanced well.
And I DON'T mean some floor jack with a measly, round support pad like this:
Taking off the complete front steering section will make it much easier to work getting the radiator and headers out. You have to pull the drive shaft out of the motor, so the rear has to come off anyway.
Ideally, if you could hoist the entire bike up with a chain lift through overhead joists, lift up the entire bike, sans front and rear wheel assemblies, and set the whole thing down on a workbench/box set up around waist high, then unbolt the motor and lift the frame off the motor.
That way, everything's up much higher and much easier to work on.
Just remember, when you put it all back together, tighten the left-side motor mounts first, THEN the right.
