    I have owned a fair number of airheads over the past 12 or so years,done a bit of engine work, tuning, etc. never owned one of the /2 series. (I like to ride).
    I have a chance to look at a '68 R69S. Owner has had it since 1980, it has not been running for the last 10 years. I have read a bit about the oil slingers, and their purpose.
    The present owner has never had the engine worked on, and has no idea of present mileage.
    Could I,or should I attempt to start and ride it while I ponder it's future.
    I am not sure if I want to tackle a slinger change myself, don't really want the $$$ expense of getting someone else to do it.
    Thoughts,
    Thanks for any input.

    It's a really tough choice. If the slingers are full and you ride it much, you risk destroying the rod bearings, but it's a lengthy job to clean them, requiring some special tools.

    As long as you're not over paying for it on the buy in, I say go for. I'd drop the pan while doing an oil change and if it was clean, I'd fire it up and ride it around, as long as it's not already making lower end noises. You won't be doing any more damage to it than what was done the last time it was ridden.

    You might as well see if you even enjoy riding it before dumping the extra coin it's eventually going to take to go through it. Besides, when you finally do tear it down you'll likely spend so much on it that you might not even notice the extra $1,500 for a rebuilt crank.:lol3

    Keep in mind detergent vs non-detergent oil. From what I understand, if non-detergent was ran you'll want to stick with that. On a fresh build you can go either way. It sounds like non-detergent is the ideal way to go on the slinger motors. If you switch from non-detergent to deteregent, it'll pull up the dirt all through the cases that's been previously collected, too much in one go.

    Never owned a /2, so this is just my understanding of it.

    I would at least run it and ride it to see and feel if there are any developing problems. If the mileage is below about 36K, I'd ride it until any problems start to surface. A good way to check to see if it's been run on non-detergent is to simply open the dip stick hole and look inside. If the walls of the engine look almost black, it's been run on non-detergent. If the walls of the engine a fairly clean looking, it's been run on detergent oil. If it's been run on detergent oil and has 36K miles or better, it would be prudent to clean the slingers. If it's been run on non-detergent, you can probably see 80 to 100K miles before cleaning the slingers. The thing that mostly fills the slingers is piston rings and piston skirt. If it has had new rings or re-bore, the slingers MUST be cleaned before the motor is pressed into service.

    If it is a good price that you can afford, I don't see how you could resist.

    Well, I looked at it.
    Has not run since '94.
    It all is in decent shape for sitting for 24 years.(He did drain the tank).
    Shows a bit of rust on the tank and fenders.
    Nothing bent or twisted. 90% original.
    Does turn over, with signs of compression.
    Still mulling over a price, he mentioned one, as did I.
    A bit apart, but probably in the ballpark from what I have heard from down south.(But this isn't Calif),
    Do I need it? - No - Do I want it? - just a bit.
    I will never get a chance for another 5 miles from my work place ( 15 miles from home.)

    You're giving me a woodie just talking about it.
    I wish an R69S would come up for sale for less than crazy retail, somewhere near me.
    That is my "Valhalla" motorcycle.

    It isn’t that far away:

    If he’s near Edmonton, it’s even closer. Just a long weekend drive... :D
    You’re welcome.
    (I picked Cold Lake because I’ve been there, and I can’t imagine any successful human outposts north of it.)

    I would also say to ride it, get to know her, have a nice day or a few weeks together before you get her naked. The experiences together will let you know if she is right for you and the memories of those experiences will help get you through the tough times and expenses of rebuilding her.

    If you are still thinking of this, I would bring some oil with you, drain the stuff in there and put in the new before you even start it. If the old comes out goopy, it was run on non-detergent, then detergent.
    I suspect the grease in all the bearings (wheels, steering and suspension) is hard or non-existent, and it will ride and handle like absolute crap. Don't be put off by that. You probably need to replace some or all of those anyway.
    24 years is a long time. I 'restored' (in a continual process) my late brother's R60/6 that had been stored for 20 years, and the condition of the grease and the engine seals was not good. It had been in a garage the entire time, 15 of those in California. Nothing has been done to 'pickle' it- it was just parked. I did have to reseal the tank, but fortunately there was little rust.
    Sounds like this 69S doesn't need much- just everything.
    Grab it while you can.
    Then come back here to let us help you spend your money. Expect to part with about 6-10k by the time you are done.

    LOL. Sounds about right.

    I too would like a /2 someday, but, I just put $10k into a total mechanical restoration of my Guzzi Eldorado, including total rebuild of the engine including grinding the crank to 2nd undersize.

    So, the $6-10k number sounds about right.

    I thought aboutt it for the weekend.
    Called the owner last night and told him I would pass.(Price, and not sure how much more riding I am good for, also not sure if I am up for a refurb.)
    He asked if it would make a difference if he came down to my offer.
    Also said that he wanted it to go to a dedicated BMW follower,(guess I fit the bill, don't know how I got that across in 1/2 hour.)
    He wanted the new owner to enjoy it as much as he had.
    Given another day, I have to make up my mind in 5/6 hours.

    Send BMW vibes my way.
    Pete, it is in E.town.

    Yeah, post some pictures.
    I guess my sense is that it’s not a chance that will come again. If you decide you’re not up to carrying through with it in the future, you’ll be able to pass it along without losing money. If you pass on it now, you’ll never know what it might have become.
    I don’t want us to push you into it, but it is something a bit special.

    (I really like my /2, even just staring at it in the garage.)

    Buy it, raise the price $100, and sell it to one of the drooling inmates here. Take your wife to dinner.

    Like every one above said buy it do all the basic maintence that you can do ride it.

    The /2's are of a different animal lower slower but a 69s will go 80 all day assuming it is maintained properly.

    I ran out of garage space actually prefer working on later bikes.

    & you would be spending time working on it.
