    I think the Airhead in Whitworth"s post is cool. The best thing to do is sift through the advice given here and decide what is relevant to your idea of building a Bike.

    Leave the swing arm, as a new comer to bikes you won't get to the limit yet (or should'nt try right now)

    Fit a couple of Mikunis, get the thing running, get new Tyres, and ride the thing. Then save up some money for the nice bits you want and do it slowly.

    It would however be a good idea to pull the heads and check the bores, its a simple job to do on those bikes.

    I have yet to see a barn find BMW from the pre-nikasil era that didn't need everything from the piston pin up done (Rings, seals, gaskets, valves both guides and seats, etc...) in order to just be a runner. Budget $1000 at a minimum if you are going to do all this your self.

    If you haven't seen this yet...then read every stinking thing on the site and do all that apply to your bike. I know it is literally the worst designed 1990's retro website on the internet but there is enough info to keep you busy for two months.: Snowbum BMW Motorcycle technical maintenance articles, snobum, Airhead, K-bikes, Oilhead, sidecars, prostate cancer, insurance

    It is pretty cool, though...

    Imagine the compression … probably diesel
    and the shear mechanical torque of having all that shit flying around at high speed.

    BALONEY.

    What you don't see in this photo is the crushed left side head-



    I got this bike running pretty well in one afternoon. The forks were a bigger problem, having been left with the weather boots holding rain water...



    Sold it before I had a chance to really make it look nice, but it had some guts, and was only an R60

    you live in Texas where nothing rusts. I'm from the Northeast and live in the Midwest now where things rust so fast they sell "rust warranties". I'm still surprised that it didn't need at least pushrod seals and base and head gaskets. Or did it and you just rode it leaky anyway?

    Texas is far from a "no rust zone" They don't get the salt that the north east....and even more in northern Ohio...., but Houston, where I grew up gets over 30" of rain annually. And the average relative humidity is 75%.
    I always find a soap box useful to get on my high horse.

    I got a new head gasket & rocker cover gasket with the replacement head I got from Boxers by Bruce. That was it. No leaks.
