Simpson,
Here are some shots of my lower front attachment struts.
I don't know how they would work on a 4/4 system as mine is aftermarlet 4/1.
I ended up making my own rear attachment struts to narrow the bags to the bike, but the front lower ones are stock as far as I know.

Some reason I'm having trouble attaching pics....here's a couple more....maybe!

Simpson · « **Reply #152 on:** July 27, 2011, 04:58:51 am »

Thanks a million for posting the shots! I heard of that support but never seen it. The 4/4 makes it a tad more tricky to route the support. Have to think about it some more.

No problem!....And your bike looks great!

And riding without bags is like wearing pants with no pockets.......my .02 worth!

Okay...

So as I approach 25k the oil leak from the head went away but has come back 2 fold.
This winter I am forced to do a top end re-build.

This is my list of upgrades or fixes I'm hoping to accomplish.

-Top end rebuild replacing all seals, gaskets and piston rings (cylinder hone, valve lap etc) - Most parts ordered
-Seal engine tight for future synth oil - Investigating
-Refinish external surface of forks - Waiting on Fork dismantle, service arranged
-Upgrade forks with progressive springs - Ordered!
-Update Wheels with new Honda spokes - Ordered!
-Update cam chain train with Honda original parts - Ordered!
-Fix random hole in unicorn tree from Previous owner - Weld and powder coat Investigation
-Consider Handlebar vibration update - Investigating

Tomorrow I complete the tear down and get the motor out...

I think the lesson here is that if you already have the engine out you might as well fix it. You sure have a great bike. I am sure it will give you many more years of service.
You have done a lot of work to make it a good bike too!

Very true, I should of rebuilt this engine when I had it out last time.
I desperately wanted it to be an unspoiled machine, meaning before I touched it no one has even opened the tappet valve covers.
The idea of seeing how many miles it could run on just good maintenance was too tempting.

Runs great now but the oil leak is getting bad.
Before pulling it apart couple weeks ago the compression measured within about 3% of each other.

It was a smooth sounding machine.

Since I'll be in there, might as well update several weak points line tensioner train, seals and what have you...

On a side note, I definitely getting more proficient taking these things apart and it gives me a chance to give it a good cleaning.

Simpson · « **Reply #159 on:** January 02, 2012, 06:39:25 am »

On a side note, I will not re-install the saddle bags. My wife and I will soon be buying a Goldwing within the next 1-2 years.
This gives me an opportunity to shine up refinish parts and move towards the classic configuration.
Until then we will just use the detachable top case or use a backpack for trips.

-Top end rebuild, thousand pieces

gaskets - All surfaces ready for assembly. Bad case of baked on old gasket, created "Worlds Strongest Gasket Thread"
Required paint remover, high pressure washer and 3M gasket remover tool to fully clean surfaces.
piston rings - Next to complete
cylinder hone- In machine shop
valve lap - Next to complete

-Seal engine tight for future synth oil - Investigating
-Refinish external surface of forks - Waiting on Fork dismantle, service arranged
-Upgrade forks with progressive springs - Ordered!
-Update Wheels with new Honda spokes - Ordered!
-Update cam chain train with Honda original parts - Ordered!
-Fix random hole in unicorn tree from Previous owner - Weld and powder coat Investigation
-Consider Handlebar vibration update - Completed!
Scored a vintage vibration handlebar set on ebay. The vibration is non-existent until I hit upper speeds past 65-70.
It's not bad, I use the bike for a lot of trips with my wife. So any helper, like the throttle lock is nice.

Enclosed are pictures current state of bike, somewhat vintage vibration handlebar update purchased and some of the gasket removal tools.

Simpson · « **Reply #161 on:** January 26, 2012, 07:22:07 am »

Current State:

Cylinder honed, valve inspection in process.
Concerns on cylinder #1 exhaust wear. Valve seems to have slightly more play.

I replaced my 550 with a vintage ('77) Goldwing with a Vetter SS and Bates bags/trunk last Fall. One highway ride and I understood why they are so beloved as touring bikes and really came to appreciate the benefits of a dresser.

The engine is amazingly smooth. I do want another SOHC4 as a commuter around town bike, but I plan on riding the wheels off the 'Wing this year.

Okay parts are starting to arrive, so the bike can hopefully be put back together.

Just got the rims back from the chrome platers, the new NOS rotor came in the mail and the spokes I've had for awhile.\

No, I've never laced up a rim and it shows.

Simpson · « **Reply #166 on:** March 03, 2012, 12:55:11 pm »

Success! Laced up... Now to figure out how to true these suckers.... $:-\$

Simpson · « **Reply #167 on:** March 06, 2012, 02:53:24 pm »

Laced and trued last Saturday. Not perfect but seems to be good enough.
Did myself during Rainy afternoon.

Triple tree back, little upset the cost of doing this one part along with some imperfections.

Simpson · « **Reply #168 on:** April 09, 2012, 12:48:49 pm »

Just a status report...

-Forks arrived back from california and assembled
-Wheels laced, trued, with new modern road tires front and back
-Triple Tree ready to go
-Head should being coming home soon!

Coming along real good. Are those Dunlop 404's? I run those on my KO and K6 also. You making me want to tear down my bikes and do some serious detail work.

Actually they are the Duro brand. After trying them out, I actually like them. Tire life is great and traction seem fine.

Time to put this thing back together again!!!

Really enjoying this thread and very good photos. What did you do to the front forks - I may have missed it.

Glad you asked! Just got a new camera yesterday and I'l about to post a bunch.

The forks were dis-assembled, cleaned, the casings were refinished by a guy in CA and the springs updated with hyperpro progressive.

Simpson · « **Reply #174 on:** April 15, 2012, 11:25:06 am »

Here's a re-cap of my assembly today with the head rebuilt by Mriek.

Note the "My CB750 Book" in the back ground.
There's a plug for you Mark.
