Sounds like 'Krossthread's' ST... I'm only seeing the red X here at work.

Odometer broke at around 40K; previous owner estimates total mileage to be a bit under 75K.

R80ST Riders Registry

I started a Registry* over on the R80ST Rider's Group (yahoo) being the central
locale for all things R80ST. Figure the more data the better for us R80ST owners! (*BMW R80ST MOTORRAD REGISTRY)

If you aren't a member and own a R80ST come over and sign in.
The list has been VERY helpful for me so far in addition to what
ADVrider has given me. BOTH sources in tandem are super, so
don't think I'm trying to take away from here by any means!

I could enter in your info with permissions etc., but then if you ever wanted
to update your record I would have to do it for you. Would rather have you
all on board.

Best Regards,

Andrew

Andrew,

Is this the link to your registry?
http://autos.groups.yahoo.com/group/R80STriders/

I don't find the "BMW R80ST MOTORRAD REGISTRY" on Yahoo groups.

I think you're right. I know Kirk participated in at least a few events with the SoCal Airheads.

I was able to view your pic at my home computer and that's the ST I was thinking of.
Eugene Kirk Krossthread... Rusty at Bob's NH knew him, Kirk referred me to Rusty when I was looking for a bashplate.

I believe your bike was well maintained.

I don't doubt it for a second. Kirk is a good guy, and has continued to give me information and advice. He said he'll teach me to tune the carbs & set the valves, etc. He was sorry to sell the bike, but he needed the cash to get his wife a new vehicle. I will try to maintain the bike to his high standards!

Yes, you hit the right place! You have to sign up for the R80ST Rider's Group
and it's well worth it having an ST. No spam or barrage of emails from there.
Group has been around a while so a good wealth of model specific knowledge
is there. OF course all of the Airhead knowledge on ADVrider in tandem is
worth it's weight in gold. Both sites have helped me. Hugo who moderates the group is in Tokyo. He has some cool pics of riding his bike in the snow in Japan.

Charging system

Went riding today. I do short jaunts on back roads since the bike is still "new"
to me. The longest ride I've done yet is 100mi. Generally get out and roam
for about 30mi. like today.

When I bought the bike, the previous owner gave me a set of brushes
and mentioned having seen the generator light come on at speed as of
late for him. I've ridden the bike a bit on short trips over the last few
months with last weekends 100mi.'er being the first time for me to see
the generator light come on.

Seems that when the bike has been running for a bit and gets good and hot
is when the light is coming on. It's all stock, so it's no big surprise. Any tips
from you seasoned ST guys? Replace brushes only? Anything else (diode board)?
Later i'll put in a better system like enduralast or motoradd elektrik's rig. For
now I can't have the bike dying on me like it did twice today!

Any help appreciated!

Andrew

I have yet to witness brushes wearing out.
I have seen them jammed immobile in their slides due to dust and crud, not that they need to move much but they do need to slip freely in the holder with the spring pressing down at the top.

Easy enough to look just by pulling the front cover, look to see how close the coiled spring is to touching the brush holder. If the spring's hairpin turn is resting on the brush holder then your brushes are worn and need replacing.
Three more screws plus a few connectors removed and you can have the stator housing in hand to inspect the rear brush.

Do you have a spare alternator rotor?
Has yours been replaced recently, with a fresh one from Motorrad perhaps?

They're known to fail after 30 years in service. Mine failed this summer after a long run on some washboard.
I believe it's possible you may be seeing windings open due to high temps. The stator is not usually the culprit.

Under what circumstances did it die? Not idling well?
If it died and you used the starter button to restart then it didn't die due to brushes and the charging system.

When I say died, I actually mean the battery (which is a fairly new Odyssey)
was dead so it's obviously not charging. Battery going "click-click" in other words. Had to sit and wait for a small reservecharge to get the bike started.

Will charge the battery up and check it. Then I'll start with brushes and voltage regulator troubleshooting. From there move to diode board if that's not the issue. If that's not the case will go through the rest and of course check all
connections.

We are sure it is the gen light coming on, and not the oil light when it is getting hot?

Ha ha...oh yes! Definitely generator light. I must be getting "some" charge,
but it's not full on. The light is dim when on, and sometimes flickers. To me
seems like brush "bounce" but V regulator going out can do this too?

Talking ST registry

I have an red 83 ST the last four #'s are 7224 looks like I have the second bike imported in the U.S.? I've had the bike for about 8 years and bought it second hand from a delear in chicago who sold it new. I have installed a PD Tank and PIAA lights mounted on a bracket that I found on ebay.de for the 79 R65. I plan on doing a complete service this winter on it. some mods I have been pondering is R100 jugs, taller 5th gear, a kick starter and upgrading the electrical, however I am not sure what electric system to use Endurlast or motoelectric?

Castironmeyer,

Congrats!

Looking at the serial #, though I don't think your bike would be that high on the import list - the first page has everyone listed in ascending number order. Without looking up your production date, I would guess it falls into Spring of 83 sometime. Mine is 7051 with a build date in Oct, 82. Hard to tell the sequence of imports, though.

I wonder if BMW can provide import info on a serial number?
