    New member / new bike

    Traded a old honda for 73 75/5 toaster. It needs some work but not real bad. I need to replace the right head and wondered which years/ models interchange. The bike looks pretty cool but dont know much about them. All the body work head light stuff is there and in great shape. I think it hit a curb then got parked. is it worth fixn?

    Is it worth fixing? YESSSSS

    It is one of my favorite models, I love the tank. I don't have one, and never have, but if things worked out I could see myself with one. Welcome to the Forum and post photos as you work on it.

    Total write off... I'll take it off your hands, no charge

    Not sure what heads you can use, I do know the rockers changed in '74 (http://www.largiader.com/tech/rockers/). How about a picture of the damaged head?

    The best thing you can do is to join the Airheads (airheads.org) in your area. Most hold Tech Days where you'll be shown how to fix your bike. Many experts who can figure out your problems. I was at a Tech day here in Florida yesterday. I took a dissembled gearbox to get opinions on what was needed to fix it.

    Edit: Looked at Max BWM website and the part # for your head is 11121337870. This same part number is used for the all R75's (/5, /6, /7). Other here will be able to say if you could use a head from a different bike.

    Unless your new bike is seriously effed up on the inside, I'd say you definitely got the better end of that deal. Very nice work! 1973 R75/5 LWB (Long Wheelbase, which yours looks like it could be) Toasters are among the most desirable BMW bikes of the 70's, and yours looks to be in very nice condition!

    Welcome aboard Mike. What a sweetie!!! Too bad it's a total write off. I'd leave it out on the curb for the scrap guys ... where'd you say you live?

    I've been riding a '73 R75/5 since 1974. Take a bunch of detail shots of it for us.

    Did you mean "head" or "valve cover"?

    More pics

    So the frame was bent but its not any more. They are not the toughest frames as it pushed bact into shape pretty easy. The guy i got it from thought it needed a whole motor. It made crunching noises when you pushed it. In neutral. It bent the frame and the drive shaft hit the inside of the swingarm. I think it would run but it would leak oil out of the damaged head. It didnt hurt anything inside except the head and cover. Looks brand new inside.(35,000 miles on speedo) From what you guys are sayin I think I found a treasure. Never had a BMW before it sure is easy to work on.

    Check out the Flea Market

    Dale Linhert had a set of heads for sale for that very motorcycle. Don't know if he still has them but I've been real happy with all my dealings with him. He might be able to help you out with any lingering frame issues to.

    Never mind.. .. .. wow. I'm trying to visualize this bike sliding along the pavement and then hitting a curb.

    Bent frame, tweaked swing arm, crunching noises ... .. and who knows what else. Looks can be deceiving, and one man's trash is another man's treasure.

    I'd send the frame out to be checked for alignment/structure if you decide to keep it.

    Im pretty good at fab work. I got the frame perfect. It does need right head, Needle main jet and the nozzle that it screws into. Points and condenser are missing and right side cover is gone and no key. Thats it. The motor is tight and clean. Any help finding these parts would be awesome. Im a pretty good TIG welder and machinest if you guys need anything like that. Check out the frame jig. That and a porta power made it easy to straighten. Whats the best ignition system for these bikes? I like points myself, are they reliable if set right?

    You might want to check around to Ebay, Ibmwr.org, and other dismantlers to locate a good used frame. It might be worth the money to replace it with a used one. Just thought I'd throw my $0.02 in here. On the other hand, maybe the frame wasn't out that much and you are sure it's now all straightened out. Anyway, best of luck on the restoration.

    Hucky's BMW Parts has a key (among others) which looks like tis:



    As Jeff mention Internet BMW Riders Marketplace is a great resource.

    MAXBMW is another (especially microfische files).

    Ted Porter's Beemershop in Scotts Valley, Fornia. Well versed in "airhead"; the best shop on the left coast, for my money...

    Vech's Bench Mark Works ... way long on BMW experience.

    so how old is that picture in the first thread, what does the other side look like, not just the head

    for sliding down the road, bending aq frame, bending the swing arm, engine making noise

    that picture is not what I would imagine to see

    regardless, that picture is a beauty of a bike
