What to look for specificially? any common problems? The bike Im considering is 1 owner and has approx 125k on the odo...
When I was shopping for an upgrade to my T3 Guzzi's electrical system a couple of months ago. I saw that 450 watt alternators are available for some BMW's. I don't know if the bike you are looking at is compatible with these, but it's worth a look.the electrical system is not going to run a bunch of lights or full heated gear.
No, those carbs are Bings which came on all airheads except the R90S. The R90S had Dell'Orto slide carbs. Probably an R90S front wheel set up to get the dual ATE brakes.R90/6 did not have dual front disc brakes. Also has R90S bars. It might also have the larger R90s carbs - the intake tubes look larger than stock.
Thanks for the info...unfortunately the original owner is 92 and not long for this world... not sure what info and receipts are available or can be easily located...R80s are considered quite reliable airheads with few problems. The transmission output splines that drive the clutch friction plate are prone to stripping if they are not greased on a regular basis. The original valve seats were too soft for the transition to unleaded fuels in the late 1970s and would recede into the cylinder head. The original owner would or should have info on when the splines were last greased ( I and many airhead owners used Honda Moly60 so there is that to deal with ) and if the valve seats were replaced by BMW or later in life. I rode my 1981 R100 to 120,000 miles but I did get a valve job at 80,000 miles because I did not have history on the bike prior to 75,000 when I bought it and had to replace the transmission output shaft at about the same time. After that I pulled the transmission back about 3/4" to grease the splines every 12,000 miles. These are very simple bikes and easy to work on.
I agree...not a fan of the fairing...nor the seatRip the fairing off, but some R90/6 bars, and find the stock seat, and she should clean up real nice.
Here's a pretty nice R100/7 with only 23K miles on it. Fly and ride home.

All original, 2nd owner, 23,000 miles This bike rides and handles great. extras: saddles bags, tank bag, tools, manuels.sfbay.craigslist.org
The 1978 R100/7 is probably the nadir of the older Airheads. With 23,000 miles on it, it’s just broken in. Just a word of caution: odometers on these bikes were notoriously unreliable, and often don’t show the true mileage. Very easy to work on.
I’d recommend a compression test before handing money over.
As Ray said, they often had seeping oil leaks, mainly the pushrod seals. Easy to fix though!
Good luck in your search!
Your right, I don’t
Yes correct I remember now about the Dell'Orto carbs Trying to remember if the R100S had CV type carbs. The intake tubes look bigger than I remember though.No, those carbs are Bings which came on all airheads except the R90S. The R90S had Dell'Orto slide carbs. Probably an R90S front wheel set up to get the dual ATE brakes.
