A question regarding engine rotation: must I disconnect to oil lines (old type, all lines at the bottom of the swingarm) or will they bear the bending? I need access to the front rocker box cover, could this be done without fully rotate the engine and leave it on the jack halfway down?

Oil lines OK left connected on '04 XB, except (2) at base of oil cooler.
Engine always supported by jack/blocking.
Once you're in there, why go only half-way?
: )

I was impressed with XB's multiplicity of mounts re-aligning so nicely at engine reset following rotation.
However, now it seems to vibrate and shake differently than it did before rotation, particularly at hard decel/braking.

Thanks for the reply. I was asking about halfway rotation in case the oil lines would be stressed too much. So I will give it a carefull try this way.

I always try not to disconnect oil cooler lines, but leave v-bracket mounted to the engine and have it rotated with it. Oil lines are a PITA to install.

Novice at this/Buell: I followed '05 factory service manual's procedures.
Good tip at oil-cooler & Y-bracket.
A lot of disassembly - reassembly with engine rotation, none of it tricky.

Procedure as described in the SM is much too time consuming.

I usually
- remove chin spoiler,
- remove sprocket cover,
- remove muffler,
- remove driver footpeg mounts,
- unfasten coil, but leave it in place,
- release clutch cable from handle,
- disconnect rear oil lines to swingarm at engine (and found out yesterday that it's not necessary, just as you said),
- support engine by a jack,
- disconnect v-bracket from frame,
- disconnect upper tie bar at engine and rear tie bar at frame,
- losen rear isolator pivot fastener,
- remove front mount
and then I'm ready to rotate the engine.

I don't remove fuel line, connectors and the venturi stack. The wire harness can be released in the middle of the front also and follows the engine nicely without being stretched.
