Steve,

Just wanted to add, when the time comes to actually buy handlebars, most right-side-up bike shops will let you take new handlebars out to your bike. Make a (NO TOOLS) test fit on the parking lot, one bar at a time. Good chance they will have the right stuff to fit you, after a few tries.
Just for future reference . . . 

Dean, on the internet I have been looking for FJ engine guards and ran across,

are you familiar with this group?  I have been inclined to join, which is required to purchase the engine bars and other items that they sell.

A very kind offer Dean...You're the best!

FJowners,
Just a quick note to add that Europe and the UK have lots of FJs on the roads over there, and they still have many good sources for FJ parts. They also have independent 3D printed plastics (or the .STL files for making them). You may want to join a few FJ forums across the pond, for better access to the non-USA FJ parts. Beware of any shipping and tariff charges, of course.
 

You have offered a lot of alternatives. Thanks!
I am only at the initial stages of learning what needs to be refreshed, renewed or replaced, and whether the engine will turn over or needs further work.  So a lot of discovery remains. 
Today was spent dismantling the front brake and clutch reservoirs.  Both exteriors are pretty weathered and have lost the white painted lettering on their covers.  My plan is to clean up and repaint the exteriors of the reservoirs and use kits to rebuild the innards, and also replacing the hydraulic lines. 

The Buell pegs look great and I will replace the Yamaha pegs with them to gain that bit of additional leg space.  That assumes, of course, that those Buell pegs are still available, which has been a problem with sourcing steering modifications.  Randy at RPM has steering risers, which may help.  Also, I will be trying the ABM Superbike Handlebar Conversion Kit for the Yamaha FJ1100 1984~86, which I purchased from Bikermart in the UK.

If your plastic throttle cable connector needs replacement I found this on eBay from a guy who 3D prints them for the VMAX bikes, it looked the same as the one on my FJ in the pictures so I took a chance and it's identical.

I have no affiliation with this guy, just sharing a replacement part that was helpful to me. My experience buying was good, he shipped quickly and the part seems good quality. The screws thread tightly into the body so it seems like it would last a while.

I'm assuming it's heat resistant enough to not melt but I may wrap mine in some insulation just to be safe.

I just used the fj stem in the 2008 gsxr1000 triples. You'll have to build up the bottom of the stem. Was done by running some welding beads around the base. Then machined down to the gsxr stem diameter. And pressing it into the gsxr triples. Could be done with any brand front end. I suppose.

Thanks Red!
 I've added ABM to my vendors list for FJ handlebar conversion kits. German TUV certification is a definite plus.
I would worry about Chinese quality.

The ABM kit comes with a longer single brake line for use with the oem line splitter...however if you have double brake lines you'll have to call Robert at RPM and have him make you a longer double brake lines along with a clutch line.

Cheers

The is company offers a service to make a custom stem to mount any forks to any motorcycle. I have a 1978 CB750 and this is a popular mod to fit a modern 2000's sportbike front end onto the old Hondas and other bikes from that era.

I'm considering seeing if they could make a stem to fit a modern R1 front end onto my FJ1200 but won't cross that bridge until I finish my CB.

In switching your stock FJ front end to a modern sportbike front end like R1 that should open some more options for you to install risers of your hight preference and superbike handlebars which would make the riding position better. But it's a costly conversion. $400 for the custom stem plus whatever you spend on used forks from eBay plus the risers and bars etc.
