    This is my first Airhead. I got a great deal on this donor bike. Sorry to all the purists out there, but I'm converting it to a cafe/street tracker style bike. For what it's worth, I'm not hacking up the bike. It will be completely reversible. I'm an amateur wrencher (young grasshopper if you will). I need the Airhead community input on these 2 things:

    1. R80 gas tank conversion. Has anyone done one? I'd like to see what and how it has been done previously. The stock R65 tank is damage and I happen to have a cleaner R80 tank. Besides, I like the look of the R80 tank better. Pics of what has been done previously would be nice.

    2. I'd like to wire up an aftermarket speedo to the existing wiring harness. Any recommendation on a speedo? Acewell has some nice ones, which I'm leaning toward. Also, if someone has a wiring schematic they can share or written notes, I'd greatly appreciated.

    Here's some pics of the progress I've made so far: 03B564E7-7861-4FE2-9A25-7E49EF2EDFBF.JPG IMG_9859.JPG IMG_9860.JPG

    Tough crowd hey Planetducky :D.

    Re the gauges, there is a bit of info here: http://advrider.com/index.php?threads/hpn-i-just-want-one.787760/page-12 . I have a Trailtech Vapor and to be honest it's crap and needs rubber mounting, or it will reset itself at random (which it still does on occasion) The SpeedHut gauges seem nice ($) and when I contacted the owner he liked them.

    Welcome to the mad house :beer.

    Cheers,

    Adrian

    Thanks Adrian. I didn't expect much love going into this. I have thick skin, so it is what it is.

    I like it. It looks like you already set the r80 tank. What problems are you having? I installed an acewel on an r65. It did fine for 8 years, then it failed. There is some detail in the acewell thread. I can dig up my wiring diagram. I’ll have more time later to post. Good luck with the conversion.

    Thanks for the response CAW. The R80 tank isn't installed yet. I just set it on the frame just for pics. I ordered a bracket from BMW specifically for the R80 tank that I will bolt onto the R65 frame. That's my game plan. I was hoping to get some feedback from member(s) that may have done this conversion before.

    If you have notes on wiring diagram, that would be very helpful. I'm going to go with Acewell because they have a digital speedometer conversion cable that's plug and play. I'm tackling the wiring last. Here's where I'm at right now.

    R65's are a good platform and they handle so well.
    Mine came as a former racebike, I just added the seat, tank and wheels.
    Doesn't seem to attract the rivet counters much :rofl
    Even the badges are fakes.

    Very nice and clean sir. I see you've been to Vietnam. I just spent 2 wks over Christmas going from North to South with the family. It wasn't on a motorbike though. I'd love to do what you've done, but the wife objected.

    The R65 urban tracker project is close to completion. Thanks to forum member CAW, I was able to sort out the wiring. Ended up using a small Acewell speedo and kept the original wire loom. IMG_0242.jpg IMG_0243.jpg IMG_0240.jpg

    Lovely work.

    Have you considered pinstriping the wheels with matching orange.

    Right now the orange looks a little centralized, and the wheels a little flat.
    That would give it a nice sense of detail and scale. :beer

    One more thing... Did you shorten your forks? Looks like you did. I've always found the original R65 to be quiet agile with less rake, and trail then the other BMWs. If you shortened the forks it reduced the rake even further. How has that effected your handling?

    It looks to me like the wheels are pinstriped orange. :robin Oh never mind. I see you photoshopped them in.

    Overall, I like the look, but what makes the back of the tank sit so high?

    I did my first ever street race in Feb using what is an R65LS dressed up to look 1972, the handling and steering of the R65 is superb, odd really as the other race bike has Ohlins on the rear and racetech front fork inners....
    I'm keen to build a Helmut Dahne Imola Replica using R65 bits and a big bore kit....it would be blingtastic.
    My ST has the same forks and I really like riding that on a twisty road.

    Hi Jim,
    Thanks for the feedback. I agree that the orange is a bit centralized and doesn't completely flow all the way through. The orange pin stripe on the wheels is a great idea. I had thought about a partial pin stripe on the wheels before. Thanks for the photoshop pic.

    Yes, I did lowered the fork by 1". I mainly did it to lower the bike as I'm not an overly tall guy (5.5'). I have not ridden the bike with the lowered forks yet as the tank was just finished. We'll see how it'll handle.

    I had to add a bracket to the frame in order to secure the R80 tank. In doing so, I decided to raise the rear of the tank a bit so that it doesn't sit flushed to the seat. In my opinion, it also improve the line of the bike from front of the tank to the back of the seat. I'll take a pic of the bracket and post it. Thanks.
