S90: Major Milestone

Hit a major milestone today by dropping the engine out of the S90 for the first time.  Everything went pretty much "by the book" according to Clymer's, with no real surprises.  The only hiccup came when I couldn't get the engine lined up to the mounting holes for the re-install.  Then I realized everything would be a lot easier with the bike lying on the ground instead of standing up.  Once I laid her down, I got the engine installed in about 30 seconds.

The whole exercise took about 2 hours, so now that I know what I'm doing I'm sure I can do it much faster next time. 



First the drive sprocket had to come off.  Had to re-slot these screws and then hit them with the Lisle.  I don't really understand why you have to remove it just to drop the engine, though.

Detach neutral switch.

 

With all 3 engine mount bolts removed (plus the clutch, alternator, air box, muffler, carb, and gearshift) - everything drops right out.

 

Doing research after the fact, I learned that the ignition coil is supposed to be mounted to the top of the engine.  Clearly it's not.  I think the PO mounted it to the top of the frame where the winker relay is actually supposed to be.  Not sure why, but assuming it's another of his trail mods.

 Years of accumulated crap.

 First ever look at the rectifier.
