I roughed in then body work on fairing then hit it with a few coats of slick sand polyester.

Comstars are not a much used wheel , many other better looking alternatives out there.

I blocked down the polyester and threw a few coats of primer on fairing today.  Pretty happy with the results.

Fairing looks great.  What do you have in mind for the paint job?

The separation is final.  Tough job for one guy.  Kind of like a Rubik's cube.

You might want to take Hondaman's suggestion and grind down the inner lip of those lower engine mounts on the frame.  The motor often hangs up on those as you try to reinstall it into the frame.  If possible, get your motor finished first, lay it on its side and mount the empty frame around it and bolt in. Easiest method.

Thanks for the assistance.  That is how I took it off.  But you are right.  Those flanges hung me up a few times.  I will do that when de tabbing the frame.

Oh man is this GOOD advice. I ground down the lip on the front right mount and it made all the difference in the world when reinstalling the engine.

I cut and ground tabs for a couple hours this eve.  Made some progress there.  I modified the inner splash guard to be able to work with tail section installed. Also mocked up some gussets. Here is a rough of a scheme I have been playing with on the computer

One more version.  This time I lowered the fairing down a bit and modified the stripe through tank and fairing.

Thanks!  Is it something I will need in order to connect the stock wiring harness or can it be stuffed into back of headlight?

I haven't tried it but doubt it can be done. The pigtail coming from the stock main harness that enters the junction box is too short to reach the headlight and the F bucket is a little shallower than the K bucket. I also haven't tried using a 77/78 F harness either! Those do not have the junction box. Perhaps. I'd love to see you find an easy solution as I'd like to add an oil cooler to one of my F's and that's where I'd place it. 
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

Thanks Mutha.  That was my worry.  It is an ugly unit.  I just may have to make a new harness to clean it all up with out it.  But if a later model harness is available, that is probably a way to go for an electrically challenged guy like me. 

Even if the lines are long enough, there probably isn't enough room to stuff it all in the F headlight.   >:(

I ran a Bates type light with stock harness doubled over a lot of the wiring bunch, and taped it. Tucked it under the stock tank.. Would pop out or hang down. I am sure you could hide most under there, and make a few longer wires to get where you need to go.  Be much easier if you trim some of the unneeded off the harness .
 I usually run bare clutch lever, a 70-72 right hand switch/throttle housing . That gives me Off, Low High for lights , kill switch, and starter button... I used that for the horn.
 If its a 75 76 harness , you may not want to cut it , get another...earlier has less fuses ,no clutch interlock..etc

...for an electrically challenged guy like me.

Just jump into the deep end like me.  If you can wire a guitar you can wire an old motorcycle.  I ditched all the Honda stuff and started from scratch.  I'm working on the wiring right now and everything is going well.  I've just got the handlebar switches left to do.  Everything seems to be working fine so far.  I won't know if the electronic ignition works yet until I try to start it, but I'm pretty confident I got it right.

There is so much bull in this wiring harness.  Cornfusing.  Even with the diagram.   :)  I have wired choppers all my life, breeze.  10ft of wiring and the bike was done.  But this little import has me wondering where to start.  Originally, I was going to run kick only and no turn signals.  But know, my old ass is thinking....electric start is nice.  ;D
