ENGINE (Again, not detailed, just general order)
Install main bearings, check crank end float, shim as required. Install rods to crank, install built up crank & cam with appropriate thrust washers per model. Nip up cases. If appropriate, install rear crankcase breather assembly. Install cam drive & oil pump. nip everything up & install cover. Install ignition rotor & stator, inspection cover.
Assemble transmission and install in tranny cradle (don't forget the thick spacer washer between the top mount & tranny cradle). Install front isolastics in front mount, assemble front mount to crankcases, install bottom end in chassis.
Test fit inner primary cover, check backside shimming to standoff post, shim as required to avoid stress fractures to crankcase mounting area (front three bolts). When front bolts are snug, you should have shimmed the standoff to the point that the shim(s) are just snugged up by adjuster nut.
Install engine sprocket & clutch basket (observe circlip, spacer cup & spacer shims as required) with primary chain all at once. Assemble clutch, install alternator rotor & spacer, etc. Install alternator stator, nip everything up & install cover.
Install pistons & rings, then cylinders with cam followers (base gasket). Assemble head leaving rocker settings loose, then install head with pushrods. I use thin strips of cloth jammed in pushrod tunnels to hold the pushrods captive in the head while I lower it in place. Just before setting it down on the head gasket, I pull out the strips of cloth. Fiddle the pushrods into place while peering through the exhaust rockerbox inspection openings with a small flashlight. Nip everything up.
Install carbs, headers, top steady, electrical, gas tank, etc.
FIRE IT UP!
