Got a timing chain but I don't have a riveter? What the hell would you do with a riveter?
You can get an endless chain from DSS crack the cases and do it right, or get an aftermarket chain with correct masterlink for that chain if you didn't want to split the cases and make sure that journals are clean, but a riveter?
  Oh, and just I love that chopper.

It has the master, but I don't have the tool to make it work.
Have not had luck finding an endless chain.
Cases are cracked right now.

It has been a ton of fun, even with only a few miles of use.
I really need to clear off the project roster and get this one buttoned up.
I'll have some time in the shop tomorrow.

Really the master chain bit is holding me back right now.

Well the plot thickens a little bit.
I thought that I could just lift the crank up and slide the chain off to install an endless chain.  That seems not to be the case.  With the primary? chain in place I cant get the crank high enough to slide the chain off.  I assume that the shaft needs to be pulled out some how?  Cant seem to figure out how it comes out.  Any tips or help?


The one side, assume the bearing needs to be pulled as well?


Doesn't seem to be a good place to push from

There is a few ways to do it, this is the way  I do it.
I take the threaded rod from the drivers foot peg and screw it into the primary shaft on the clutch side, put the nut andwasher on the other end of the rod and either make a slide hammer out of it or set a wrench on the shaft in front of the washer and nut closest to you and gently tap towards you, removing the primary  shaft and and bearings together as one unit. Watch the oil pump side so you know how it goes back together.
Once that is out remove the chain and crankshaft together as a unit and do what you need to do .
 Goes back in the same way, align the shafts bearings and all and tap lightly back into position. easy peasy.

Oh , forgot it was a chopper and you don't have the stock footpeg mounts.... the correct size and pitch  bolt can be substituted for the stock foot peg rod into the primary shaft. still easy peasy.

I was able to do something very similar.
Didnt take much force at all.

Thanks for the tip

Well I tried to ghetto install the master link and was just not happy with the results so I ordered an endless chain.
Should have done this a while ago.

The hits just keep on coming.
Had some time in the shop to get the motor back together.....On the one side of the gear shaft is a needle bearing.
Seems that I am now missing a needle......
looked in all of my bins and bags from this motor.  Will need to go behind the bench and look.  Kinda pissed at myself.
Dont know if it is a part I can buy new, or if anyone has one.....

Good deal. I've seen people grease these bearings with axle grease to keep them together in the basket, don't do it, axle grease doesn't break down well there. I found it in a couple of old  motors so far...hampers oil flow for a long time as far as I can tell. There is probably some other engine building grease that would work...I just use oil.
Just sayin, in case the temptation of axle grease hits you.

The time has come to get back to this pile of awesome!

For a while now the bike has just been sitting.  I never put the motor back together or did much of anything.

Insert a million excuses of working of the Seeley or playing with Nortons.......

Well now I would like to get back to this bike so I have something funny to take to the local Cars&Coffee or just to aggravate the neighbors with.

Since the motor is apart I figured I should "build" it a bit.


Plan to keep things "old school" and run modified CB750 pistons.
Scored a set of NOS pistons for under $150!
Also scored a CB650 cam for $40!

Not looking for a full race engine or anything, just something fun and interesting.
Had been looking for an Abe Henry kit for a while, but no luck.
I have a CB550 POSA fuel injector (just a carb really) that I might run. 
REALLY REALLY want to find/buy an ARD magneto for it too.


So the basic idea is to have a fresh engine to drop back into the bike.
Few other small things need doing like a new harness.

Only thing that I have not figured out is exhaust.  I cant just headers as drag pipes any more.
Bike sounds like crap, is WAY to loud....also there was that whole fire thing.....

Long story short, I am back at this thing.
Nothing crazy epic to report yet.
Stay tuned.

What a neat bike/project! I know nothing about choppers (still learn something new every day with my first project that I'm working on now) but really love the way it looks. You say a friend of yours owned it but I don't recall you mentioning if he was the original owner or if he just acquired it at some point? Good luck. Have fun. And congratulations on finishing up your degree!

While the Chopper has been on the back burner for a while, it is not dead or forgotten.
During a spring cleaning of my storage unit I moved it to the front of the garage, and dug out some needed parts.

Last season my daily ride was my Norton Commando.


And the plan was to have my Moto Guzzi Ambassador be the daily mount this year, but that has not worked out yet.


Since I only have room to work on one motorcycle at a time, the Chopper has not gotten much love.
BUT, I can cross off some small projects.  I do this by bringing some small sub systems home to my apartment and working on them there after dinner.

What better thing to work on then some outdated and rare ignition?!?!
Not like the top end is off the motor, or that the bike needs a harness to run......NOPE....focus on the important parts....

Over the winter I did score some NOS CB750 pistons for my "Gentleman's Express" engine build.
Need to find a local shop that can modify the pistons and bore the cylinders.

Have a CB650 cam, and debating on a mild head job too.

Ended up with an ARD magneto set up for a CB550, NOT a CB750 one.
I really like these units, and have rebuilt a bunch of them.  Super simple, good spark, and look killer.

BUT, I just wound up with a Roto-Faze unit!
This is just next level strange!
Really have a thing for parts that make people go..."what the heck is that?" and this defiantly falls into that category.



Will need a major service, and some rebuild parts for sure.
Roto-Faze seems to be around still, so maybe they can help.
I assume that the service parts like points, cap and rotor are used in other applications.
Just like service parts for an ARD are the same as an old tractor.

So, the plan is to use the 750 pistons in the 550 motor, right?  What mod to the pistons is needed?  I would like to do this as well.  Thx

Jaguar,

Is there a performance benefit to cutting down 750 pistons versus going with a higher compression 592cc kit (Wiseco or Dynoman)?  Or is it more of a period correct goal?

I honestly do not know what would make more power.
For me I enjoy the "period correct" part......and I bought the pistons VERY cheap.

That's cool.  I didn't know if it was a cheaper and better means than buying a $450-$550 Wiseco/Dynoman kit.  I do like the fact that it's an old school recipe.
