If you go with longer pipes make sure your brake pedal and shifter don't interfere with them. I have had that problem before with some of my choppers and I'm currently going through it now with one.

I had to move my kickstand bracket twice because of different pipe configurations.

Headers that are on it now and the cb750 drag pipes that were on it both cleared the side stand.  Not sure on the controls as they were short.

Well I got some time yesterday in the garage.  Some steps forward and some things still on the list.
Got the carbs installed and no leaks....so no fires this time so thats good.  Bike runs well with the 42/110s in it.  Still some tuning to be done and they need to be synced.
Bike also needs new points and condensers.
Starts well when cold, less so when hot....but that might be a different issue...we will get there.....
Revs OK too.

Found that the black wire from the regulator was not connected.  I was already in there with another regulator so i just replaced it.  Charging at 13.4 volts?  Better then the 12volts it was at....or no charging.  I ran the bike around for a while, but when I got home and tried to restart the bike it was low on juice.  No sure if it is still the charging issue or I just ran the battery down over the day buy starting and stopping so much.
Lights where bright the whole day.

The bike is WAY to freaking loud.  I dont like any of my neighbors anyway, but this is making me mad....

With the new steering stem bearings the bike no longer flops from side to side like it did.
At speed the bike is stable enough to take your hands off the bars.

I need to replace the gasket in the gas cap....ask me how I know....

The sprockets that are on it now need to go.  55mph is like the middle of 3rd and its just a pain in the ass to ride around town with that gearing.  Could use some suggestions as to proper gear ratio and a place to source the parts.  I know sprocket specialist but the last quote I got from them was CRAZY money I thought.

Bars are super comfortable and give great control.

Now the big issue....
There is a MASSIVE oil leak.
Its coming from behind the engine cover that covers the front sprocket.  I assume its the oil seal for the output shaft.  Or is there a chain oiler in there too?  I didnt pull the cover yet.

Was trying to get to the NYCVinMoto show at Works Engineering with the chopper this year but I dont think that will happen.

Anyway, now for the pictures.



Do you know how hard it is to take a picture of a wall with no graffiti?
Going full hipster with the bell 500 and the freebie gico sunglasses.....




Look at that tail light....







Burn marks on the seat





How cool is that points cover?



Dont call the EPA




Had a funny idea while watching those idiots on gas monkey garage the other day.....
Well I figure over the winter the motor will come out to do the head gasket and while im there I should freshen up some other things in the motor.
While the motor is out I was thinking about having the frame clear coated.  Thought that it would preserve the look and protect the bike.  That way it can still be cleaned, but have the great look that only comes with 40 years of age.  Really you have to see the frame in the light to see the beautiful green copper flakes in the paint.

What size sprockets do you have?  JT sprockets are available on ebay and are reasonable.

Actually I don't know the size sprockets on the bike now.
Just know the rear is way to small.

You should have more than enough clearance to pull the head without removing the engine.  I know it will give you the opportunity to freshen up other things, but if that's your only reason...

Smart move for me would be to just pull the head while the motor is in the frame.
I have a tendency to make mountains out of mole hills.....see my CB/CR750......

The head will limit some of the trips I would like to take the bike on, but right now it's leaking so bad I can't go anywhere on it.  So that is the first thing that needs mending.

Seems the part is NLA from Honda...

I'm sure you know Jag, replacing the pucks is a must when you have an oil leak [as well as the gasket]

I don't know about the other sohc's, but the 750's have rubber discs about the size of a nickel under the cam holders.  Commonly called pucks.  They are notorious for leaking and should be replaced and have sealant applied as an added precaution.

Oh, yes.
Thought it had something to do with the sprocket shaft oil seal.

Nothing like taking a month to take an engine cover off only to confirm that the seal you thought was bad was in fact bad.





So now to order some parts...
Figured I might as well rebuild the oil pump while I'm here.
What do I need?

Got the chopper back to my garage finally.
Looks small even next to my 125



Tried to use my cb550 ard mounting plate to mount a magneto drive.


You can see that the mounting holes are drilled for a 550 and not a 750(top)

No cigar...


So now back on the hunt for some pictures to try and figure out what I'm missing.

Still have not sat down and found all the little orings and seals ill need to fix the oil leak.
Figured I would rebuild the oil pump too.  Been to busy with school to do much wrenching.

Does look small Jag.  Still think some Z bars would look cool....

I know the magneto position is adjustable, maybe it just needs to go counter-clockwise (looking at the bike from the points side).

I can't get the magneto tucked in with the carbs.
Maybe I need to mess around a bit more.

The magneto/distributor part of the ARD can be repositioned, or laid down to fit better.  I think that may solve the fitment issue.  There are pics somewhere on this site of an ARD on a 550.

More dress up parts for a non usable bike...lol




Did finally get off my butt and order the oil seals and a few other OEM parts the old girl needed.



Thinking that over the winter ill pop the motor out for a freshening up.
Might do a "gentleman's express" style motor, so I'm starting to collect those parts.

Great looking bike! I've been dreaming of a 550 chopper for a long, long time.

You can get all but one of the oil pump seals from Honda- the last one is the big one for the oil pump cover, which they DO still sell as the water pump seal for the Goldwing. Same seal, just no longer sold as 550 oil pump seal.

Awesome! Did it include a fairly big (maybe 1 inch diameter), thin o-ring?

It's not on there. It's under the three-screw cover on the oil pump. Honda sells (sold?) those only as an entire assembly.
