Wow, you really got that KO loaded down man. You need a Wing for sure. The selling point for your wife will be the comfort. My wife occasionally will fall asleep on the Wing and her helmet visor taps me in the back of my head. Not sure how many miles we put on the Wing every year. I only ride my CB's by myself. I don't want my wife to smash my nice Yamiya duckbill seat... ;D

Great photos Simpson and I like how you pack! Thats not a lot of stuff at all! Very compact!

Thanks also for the frame photos - I agree that for everyday riding the two top attachment points will be enough. However for rougher roads I would likely put a third attachment point down by the passenger footpeg.

good luck and looking forward to seeing more. Great thread.

cheers

Yeah we pack a bunch of stuff on some trips. You should see the CL360 when we ride 2up loaded down with our stuff. I've had the CL360 carrying 5 bottle of wine on the back rack. I've recieved many taps to the back of the helment on late days. I was hoping the wing would allow her to sleep without head butting me. The wing would let my 750 become a solo bike again.  ;)

Agreed! I wasn't sure how to mount a third gracefully. I would like seeing some examplesif you have some pictures. It might be in my future pending the how my setup performs.

I have no photos or even a frame yet...this is something I have in mind for when I get some aluminum saddlebags for my RTW trip. I figure the fiberglass ones will crack under rough road conditions and so lockable alu boxes seem the way to go....like this Finnish guy who did a RTW trip on his CB750 in the 70`s....

Thought this might be interesting to some people. This is a SS brake line I found on ebay the other day. My polished new one from last year was already very rusty. I'm thinking this one should fair much better to the elements.

I would absolutely set myself up wiith a set of panniers for RTW.
The documentary "Long Way Around" is a good example.

Bronze bushings installed!
Per Hondaman suggestion, they are recessed about .200-.210.

Waiting on new felts and dust caps to attach swing arm.

I believe the seller is a member here, his name escapes me, but they make stainless lines too.  *EDIT* meant to say "braided".

I have to say, that it is nice to see that you are doing two things:

1.  Keeping your bike mint.
2.  Actually riding it and enjoying it.

It's guys like you, who I am sure have Mr. Honda very pleased watching you from afar.

Not a whole lot accomplished on the bike this weekend. Mostly waiting on parts.
Spent most of the weekend updating kitchen counter top per girl friend.

Caliper completed this morning with the arrival of new parts from Yamiya.
Installed New SS piston and cup. The genuine Honda piston finish tends to blister and the brakes grab.
Updated the seal, bleeder and paint.
Prepared my parts Magpie style and assembled like a surgeon.  ;)

Also added a few shinny new items as circled.

After a full 30 minutes of power wash last weekend to the wheels...

Doing a quick update of some hardware but not a full restoration of the wheels this year (budget will not allow). Next year I will re-chrome rim, polish hubs lightly, replace spokes and replace bearings.

This year I will clean then replace rotor with something I scored off ebay for 20 bucks and update some of the hardware.

Wheels cleaned up a bit, although I need to replace the rear tire for this coming season.
On holding pattern until the remaining swing arm parts (dust caps, felts and misc hardware) get here.

Received swing arm parts today! Now able to stand on its own.
Painter has finished and shipped saddlebags and top case.
Hoping to to get them installed next weekend.

Things to do yet so I don't forget:
1.) Bleed front brakes again, still spongy
2.) Correct rear brake rod assembly
3.) Buy new carb drain hose
4.) Check timing and Sync Carbs
5.) Tie wrap wires
6.) Install saddlebags
7.) Wire saddlebag blinkers
8.) Clean and lube Speedo cable
9.) Polish chain guard and assemble
10.) Change out fork oil
11.) Attach vin plate back on and apply new stickers
12.) Change out counter shaft sprocket
13.) Glue Shoei stickers on properly
14.) Double check every single bolt to ensure it is torqued properly before riding

BTW - She runs great for not having been sync'd yet!!!!
YAHOO!
 
I'm thinking after all these updates, it should ride like a champ...

Everything looks great! I'd have some major ants in my pants if I had a bike like that in my garage but couldn't quite ride it yet. So close!

Hi Simpson!
Bike looks great!
"12.) Change out counter shaft sprocket"  What size sprockets are running at the engine and the rear wheel?

Cliff.

I'm going back to stock again (16T). Last season I ran 18T but had to cut out the sprocket cover to accomodate the larger clearance. Since I'm getting a NOS cover in the mail soon, I'll give stock a try again because it would be a shame to cut up a new cover. I'm running my stock 45T in the rear.

Thanks Simpson! I'll have to go through my sprocket collection. I wonder if a17 tooth primary would rub on the K0 cover as well?
Cheers,

Well, I can tell you that a 18T more than rubs!   ;D And I'm pretty certain the 17T would present interference fit issues also. 17T might be in my future. Depends on the K0 cover index you have as they changed them several times. -20 though -50 have big changes because of the sprocket size and gaurd changes.

Riding Notes:
Holy crap, the seat refurb, head set bearing fix, changing of fork oil to Belray and Bronze swingarm bushings have made a huge difference. Rides smooth and more like a modern bike.
