I'm in the middle of my 750 build and honestly, I might be a bit over my head. This is my first four cyl overhaul and I'm relying mostly on old cycle world articles and what my dad can remember from doing it 25 years ago. I'm a competent mechanic, FAA certified aircraft brake mechanic to be exact, just don't want to have to rip this motor down ever again. If anyone in NE area can offer guidance, I will buy the beer and cook the steaks.

Buy the Haynes manual. http://www.haynes.com/products/productID/521. The biggest thing I can remember when doing the motor on mine was to make sure you build the shim stack for the starter motor correctly. I had mine in wrong and the starter would not disengage. First time I started it and reved it past 5 grand the starter exploded inside it's body. It didn't damage anything else but buying another starter and tearing the whole thing apart again wasn't fun.

Download the factory service manuals from www.hondatech.info any problems you have you can find the answer on sohc4.net

I'm actually in the middle of rebuilding my CB350F, and it's taking up most of my free time. I'm hoping to have it back on the road by next weekend, then I'd be more than willing to give you a hand.

Top end only there is very little to screw up. Get all the o-rings in place, make sure you re-install the oil restrictors, and adjust the valves when its back together. Triple check you get the cam chain in the right position. Don't wanna smash the valves once you get it back together.

Have you taken anything apart yet? I've got a cordless impact that makes easy work of all the fucking Phillips bolts on these things. Screwdrivers do nothing but mangle the heads. Impact drivers that you hit with a hammer work ok, just takes forever.

Eh, not having trouble so much as just a little unsure of myself, it being the first time I've done it. I'm only doing the top end so starter shims aren't an issue.

That's cool, I had done a full frame off on mine and split the cases. It needed a timing chain and a new mid-case gasket so the entire thing came out and apart. If I still had my book I would have offered to send it to you. I ended up giving it to the guy that bought the bike.

Like others have said, the internals are relatively simple. Certainly compared to a modern bike there is less to go wrong. I wasn't aware of that Hondatech website and if you can get a PDF copy of the factory manual for free that is way better that 20-30 bucks for the Haynes book.
