Re: High speed questions.

You can totally make your own wires. It is very easy to do. I recently did this. Its also less expensive this way.

Get a length of solid core copper (not carbon) spark plug wire and 4 spark plug boots.

Take off seat
Take off tank
Unhook battery (just to be safe)
Cut wire to appropriate lengths (use old wires as guide)
Attach wires to boots (might vary depending on boot, but for me it was just removing a cap, pushing the wire into the boot and putting the cap back on)
Unhook one old wire from the plug and unscrew where the wire joins to the coil
Move screw cover from old wire to new wire and push end into coil
Screw in tight

Repeat for each wire.

Other than the wire cutting and joining the wire to the boot you have to do these steps even if you bought a ready made set. Buying the set basically means they're just cut and assembled for you, this is really the easiest piece of the procedure.

Spark plug wires. D'oh!

The boots are cracked, they look like they're original, and I don't really want 31 year old spark plug wires on my bike. Since I don't know wtf I'm doing to build my own (you know, just order the boots, the coil screw-on part, and the spark plug wire itself) I just want to get some new wires, remove the tank, throw the new wires on, and do it back up. Should be a 10-minute job if I can get the seat back on...

 That's how the tank makes me feel...

Sees' is right. Couldn't be that hard to do. I asked "my guy" about it today and he said he could,but that he really cant get any great deals on the wire and it would just cost you alot of extra money to get him to do it. Thats why I like this guy.Everything I ask him about he just tells me how to do it myself so i can save money.When I got my front master cylinder rebuild kit from him he offered for me to take his brake pliers home so I wouldn't have to buy a set. You just dont see many shops lending their tools out like that. That made me a loyal customer right then and there.

As for the shake, you have a number of causes. Your tire could be cupped or otherwise damaged, even if you can see it. If it is out of round a bit or out of balance, you can have issues.
Your rim could be out of round, you need a dial gauge to check this but it would be a good idea, especially if you have spokes.
head bearings could be bad even if they do not feel like it. A quick test would be to sit the bike on the center stand and put weight on the back to raise the front tire. Slowly rotate the bars back and forth and feel for any notching. You should also be able to set the bars just off of center on either side and they should turn that direction on their own with very little pressure. If not, new tapered bearings are in order.

Some new fork oil might be in order too. If the levels are of from each other, dampening can be affected.

And finally, the road you were on, did it have rain grooves cut into it or wheel tracks? Your bike might be fine and those damn things can cause wobbles.
A cheap stabilizer is not a bad idea though but check and correct any issues first.

Just got done checking the things you mentioned Rerun

Drained and replaced the fork oil. To the best of my ability the are filled evenly.The oil that was in there only had about 4k miles on it so I dont think it was beat up too bad.Still looked clean.

Steering bearings seem ok. No notching. Bars will fall to the left like you explain,but not to the right. I noticed that the clump of wires i have on the left side of the steering neck are moving when I turn right,so I attribute that to not falling to the right since it feels very smooth.

Front rim has .030" run-out on both side to side and up and down

Rear rim has .025" run-out side to side & .060" up and down.

Is this with in specs? The .060" seems a bit much to me

Tires are still practically brand new. I looked them over good for grooves,cups or chunks missing. Visually I do not see any defects. I ran a couple laps of masking tape around the center of the tread trying to keep it smooth as possible to check the run-out of the tire vs the rim. It was kinda of a hokie test and didnt really produce any results. It did not reveal any major run-out issues at least,but i really couldnt get a good way to run the dial indicator across it.Best I can tell the tire follows the rim fairly well.

I'm hoping my occasional wobble is just road related and a stabilizer will correct since it is intermittent and rare. I've been over 100 mph probably 15-20 times and it has only wobbled 3 or 4 times at most. Once I know was more than likely road related.Tar snake.

That .060" on the rear has me concerned to be honest. Any thoughts?

Concerning my previous post I found this in the FSM.Seems I'm within specs

I just did a speedo check on my 1975 CB750 SOHC. Using a GPS I found that doing 60 mph the speedo read 75 mph. At 75 mph the speedo read 90 mph. I purchased a new cable and I am sending it out to have a calibrator installed on the cable to correct the problem. These bikes will do about 120 max if everything is right on.
All stock except Dyna-S solid state ignition and tires. It has 32,000 original miles. The complete bike has had a frame bare restore.

Between work and the rain I finally got a chance to take a ride on my new Shinko's.I'm a believer in tire profile now! I still am amazed at how something so simple to overlook can make such a dramatic difference in handling. These tires have a narrower,sportier profile that just wants to be leaned over. I also returned to stock sizes.I am a new rider and will never be one of those guys that can get the max out of any bikes suspension,but these new tires feel great.They transformed my bike from what felt ok,to what now feels so easy to ride.My 500lb pig feels more like my 200lb dirtbikes used to feel like when you could flick them around in the woods. Until I find a better tire(and I'm sure there probably is)I am sold on these Shikno's! Love 'em!

I intentionally aimed for the tar snakes today and could barely feel them

I've been riding my new stock sized (slimmer) rear tire for over a month now and the handling is definitely better.  The bike leans a lot easier, specially on slower turns and swerves which allow me to react much quicker than with my old fatter tire.
