Hi folks, long time no blog!
Something interesting happened this week. And it happens every couple of years. After not thinking much about the BMW for a while (I just finished my work busy season, which coincides with the lovely grey Michigan winter) I received a message on Ebay from a pleasant gentleman who asked if the BMW was still for sale, referencing the ad I had posted two years ago.

From the ad:
In October 2010 I bought what is call a BMW /2 “Conversion” Motorbike. It is constructed from taking a /2 bmw chassis (1955-1969), and implanting a /5 Engine (1970-1973).
In the years since it has been completely rebuilt mechanically, while preserving it’s look as an old bike.
You can keep hitting the “next” button in the upper right corner to read through it all, but here is the bike in a nutshell.
1973 R75/5 motor with Siebenrock 1000cc Big Bore Kit
Stainless steel pushrod tubes.
Lightweight 9.5:1 1000cc pistons .
Dellorto carbs, Real Paul Dunstall Silencers (not copies), SUPER rare Sig Erson cam.
New /5 and /2 wiring harness, Rear Fender Wires Replaced, Valeo Starter, Dyna Coil, Uli Electronic Ignition with adjustable Advance Curves, Omega Alternator, 12v AGM Battery, H-4 headlight, new handgrips, mirrors and turnsignals.
All engine, transmission and Final drive seal replaced.
Final drive rebuilt with new gear and spacer plate.
Head redone: Valves, Guides, Springs, Pivots, lifters, and Hardened Valve Seats

RARE tachometer installed, with specail cable to mate to the /5 engine.

“How does It run?” I cant believe that in my effort to get all the mechanical details correct I did not talk at all about how it all works as a motorcycle.
It stars, runs shifts and stops just fine! Because of the cam its happiest at higher revs, and drives like a regular R1000 engined bike until about 3500 rpm, and thats when the cam really comes on, then it pulls like a freight train! The Dellortos have accelerator pumps in them and are very responsive. The brakes have a high friction lining, but are still R69s drum brakes……
I should mention that the full persormance potential of this bike has yet to be realized due to having less than 1000 miles on the new Seibenrock cylinders, pistons and rings.
I told him that I had not really been thinking about it, and the last ad had not met my reserve, but that I would take some fresh photos for him, and add up my receipts to try and come up with a price.
And then this happened…. The bike had sat all winter, I put air in the tires and well…
Now I’m conflicted.
I mean it starting like that, even better than my newer fuel-injected toys, is no accident, its the result of 6 years of work, and a hot coil, and an electronic ignition, and endless fiddling with Italian carburetors.
Can I put a dollar value on that, even if I don’t ride it enough? To gain what? A wider driveway and a new fence in the backyard?
conflicted…
Rational brain, emotional brain…
Eros VS. Thantos … (Google that one)
