My '73 850 rebuild..

Not open for further replies.
Mine's still at my dad's, still unfinished and in need of some finishing touches (such as throwing away the stupid Mikuni and installing my amals, honing in on the leaks, figuring out the charging issue, etc). I haven't had any time to even look at it as I'm readying my house for market and hopefully readying my featherbed project bits to ship.. Ugh.
 
Hmm. Well, dad's working on the bike today. The Mikuni is getting pitched in the parts pile. The stator is still being a pain in the ass (won't charge the battery at idle even though we made absolutely certain it was centered when we reinstalled it in the primary).

As for the leaks, I don't know. I'm sure some of it is the bike trying to find its natural levels, but that can't be the whole story..

I'm going to go purchase paint supplies ($200 for the "CRAPPY" Nason stuff at O'Reilly but it's what I can afford so it'll have to do) to redo my disaster of a tank that was painted last year. Assuming the proper amount of prep-work is given this time around, there shouldn't be awful waves in the paint like the last fiasco. What a frustrating waste of money, especially after I repeatedly vouched for the person. Sickening.

Anyway, for now the black/gold tank is installed along with my stock interstate seat. I still need to get my custom seat redone as well but the bike needs to make it to my upholsterer's shop for that to happen.

I don't know any stators that charge at Idle, Some HO units will send a trickle but really not expected to deliver what you may be expecting. Not till 2000 or so will you see what you are looking for. This is normal.
 
Good to see you back here Jordan.

Maybe the rotor magnet is weak? What is your idle speed?

Time to move on.
 
Interesting information about charging at idle. Did not know that.

Hopefully the kinks can be worked out and it'll be up and running. Then if the tank and seat situations are resolved I can call it 'finished'. We'll see.

Only sort of back. Still not much time of my own to work on anything.

Not sure on the idle speed. Probably around 1000 rpm I'm assuming.

Trying. Irritated as all hell with the whole situation, even still.

Hi Jordan,

These old tarts don't charge till about 2500 - 3000 RPM (If I remember correctly). Also as batrider mentioned check the rotor, remove it from the bike and try lifting it with a wrench, the rotor should be able to hold its own weight.

As for replacements, some of the cheap(ish) eastern made replacements are pretty good, I've got 4K miles on mine so far without a problem.

Good Luck

If I remember correctly we tested the magnet before putting it back in and it was strong. Sounds like I'm expecting it to do something it wasn't designed to do.

Someday I'll ditch the Boyer, stator, and rectifier. I could give a crap less about originality these days, it would appear.

Paint update--

I took everything to a local hot rod resto place and the owner said the tank would need acid stripped because there is a bit of tank sealer that was sloshed around the bottom of the tank (?!) and is now flaking out. Once that happens, I'll take it back to the shop to be blasted and hopefully move forward on paint. It will need a good amount of body work to look 'right' but its probably no worse than the average tank from this era.

The estimated cost was actually a lot more reasonable than I thought. They looked very busy with several restorations on the floor. As I would expect, the quality of work looked solid, at least from what I observed.

I still need to work out the gremlins with the leaks and whatnot. Dad said we might have to take the bike partially down again (gearbox, primary, most likely) to really diagnose the issue. The oil tank was sent to CNW so that shouldn't be an issue. I need to replace the neoprene rocker gaskets because they won't seal no matter what I try.

That basketweave seat you have there - is that the original, or a replacement. ?

Methinks you should have saved the repaint until something happened to that paint job, looked good in the pics ?. The original factory paint was sometimes pretty thin ...
(where did the factory get the paint done, they didn't have a paint shop ?).
 
Which seat? I've bought and sold about five of them now. :p

My bike was originally a Roadster. I sold the stock seat when I ditched the tank and covers.

And what paint job? I still have the black/gold set. I pissed away $1100 on that and decided I didn't like it..so I took dad's set, which was in red oxide primer, to get it painted in the scheme I liked. It would probably be done if I'd have just looked locally the first time around. Live and learn. My bike is sporting the black/gold set for the time being.

I hope you have a kegerator in that garage of yours. It's the most important part of the build!
 
Nice. I'd be surprised if there wasn't. These Cdo's are a real lesson in patience. I do a lot of timber framing and stain grade carpentry, so I'm used to being patient. Rebuilt motor and trans coming soon from CNW, then I'm gonna start catchin up to ya! Best of luck.
 
My '73 850 rebuild..


She does two things well:

1) Sit and collect dust
2) Leak fluids (notice giant puddle near center stand)

Summer task list:

1) Remove stupid Mikuni carb and replace with the dual amals I already own
2) Track down all leaks and install new/better/whatever gaskets to prevent further issues
3) Research any possible charging problems that may or may not exist
4) Finally get out and ride this bastard

After only ten years and two engine rebuilds my '69 Fastback is running beautifully and not leaking a drop (still looks awful though, unlike yours!).
 
Well mine looks beautiful and never moves. I think I'd take your situation all day, every day. Sounds like you had a better plan than I did--lol.

I love those fastbacks!
