I can't answer your technical questions, but ebay and forums such as
http://www.atvswapmeet.com/ are good places to look for used parts,
probably much less than $400.

I've been working on my neighbor's 1985 Honda Big Red 250cc trike
lately. 6 months ago, it wouldn't shift properly and he had a guy
tear the right side case off and the guy shafted him. He said the
clutches were bad and wanted $1,000 to repair it, then he stole some
parts, "borrowed" my neighbor's DR mower and didn't return it, stole
his Husky weed eater, and a few other things like that.

I got into it about 3 months ago and had my neighbor order the factory
service manual. We ordered what looked like all the missing parts
after I tore into the left side case and found the shift lever
actuator bracket in 3 pieces. We could have welded it but he wanted to
put a new piece in. C'est la vie.

OK, so I put it back together, it shifts fine now but I'm having
trouble with the kickstarter ratchet always being engaged, as if the
starter pedal is being held down. I've tried 4 ways to reinstall it,
reading the installation instructions time and time again but I'm not
quite "getting it", I guess.

Has anyone here torn these down before? What am I missing? I hook the
spring on the cutout in the case, and align the ratchet lever with the
ratchet guide, but the index mark is 180 degrees off. If I wind the
lever around to bring the index mark up, the shaft unwinds by itself
when I let loose of it to put the cover on. This is downright
maddening!

Clues, please!

I am not at all familiar with this machine but, in general, you need to look
at the case, cover, and shaft to identify the "up-stop" where the shaft is
positioned at rest. See what disengages the ratchet at that point. Check how
the spring has to be wound and secured to hold the shaft rotated to that
point. Also check how the ratchet is engaged and the spring wound when the
starter is pushed down. This may help if no one has better information.
