Delkevic exhaust installed. 

Turns out #4 spark plug was bad;  that and idle adjustment and she is purring like a happy kitten.    I took out the bulb that keeps reminding me air pressure in rear shocks is low - because she has progressive shocks instead of air shocks.
 
She is so different from 750K, I have to really  fold my 6'2" to sit down.

I will put on her the touring windshield from Dorothy, and replace the tank lock.  Somebody unlocked it with screwdriver.

I put on her about hundred miles on local roads. I can imagine her as a commuter bike, ride all day would be painful. 

She starts quite well, yes it is Summer but still. I spoil her with ethanol free gas, she is too old for that nasty #$%*.

Plenty of power and Delkevic makes it known  ;D

I had to fabricate rear tank catch, there was only a piece of rubber.

First gear sometimes does not hold when idling, gotta shift and keep her bit under power.

Anybody have different seat than this one position only? I would love to see some pictures for inspiration.

I still want to synchronize carburetors, but I do not expect much from it.

Brings back fond memories.  I woke up Christmas morning 1983 to find a new CB900C (my dream bike at the time) sitting in my living room.  My wife bought it and had my best friend ride it over Christmas eve and they brought it in through the sliding glass door.  Only problem, it was a sunken living room and the wife wouldn't let me start it and ride it out.  ;D

I eventually put a Hondaline fairing, panniers and top case on it and kept that bike for 23 years.  I never did replace the seat and it was not very comfortable for my 5'11'' frame.  I had the fairing lowers on it and my knees and shins were pushed up to the point where they touched most of the time.  But the bike was fun, and very reliable.  Only real problem I had with it was the rear brake caliper would stick and drag.  One time I thought I'd lost a couple of cylinders because the power just dropped.  Turned out the rear brake was dragging so much it had turned the rear rotor cherry red.  WOW.

I am 6'2" and 260 pounds and I can fold on it alright but after 30 miles I feel stuck.  Commuter bike  ;D

Otherwise I love the power, she starts easily with the choke, runs like a champ.   For the size and weight, she is easy enough to lean in corners. 

I got used to feeling the shaft kick in when shifting, it may be just this bike, little warn out.

Also in Low you have to keep your foot on first, otherwise it pops up, it will not do it in High.

The rear brake pedal pivots steel on aluminum - it took some effort to take it apart and clean it.  Aluminum and steel connection is prone to oxidation.  I used vacuum grease on it.


It must been some effort to get it out of the living room, 500 kilos or so  ;D ;D

Carburetor number two had stuck float or something like that.  Had to pull the rack and clean, nothing new.

But when I put the rack back, I swapped push and pull cables  ;D ;D

Nothing like little practice on removing carburetors.

I remember hearing good things about these from some truck drivers I used to talk with at work about 20 years ago. I figured one might be in my future someday. There are several around, maybe its time?

You are right, they seem to be easy to find and cheap.  I like it - up to half an hour ride  ;D  The seat makes you stay in the same position, I will eventually replace it with just a plain bench seat.  With the original seat I eventually end up sitting on the passenger hump.
