Lacking any inspiration for a witty title, this is simply going to be called #4 This follows my previous project threads following my R80G/S, R65LS and R100RS, and this one very much follows in the same vein as the LS and RS. To start, I'll quote both the LS and RS threads: My list the qualities that would identify the perfect project bike include: #1 BMW Airhead #2 One of my list of 5 models; R90S, R69s (any /2 really), R100S, R65LS and a non-airhead a K1 #3 Local bike #4 Known History (1 owner?) #5 Stored for some time (longer the better) and needing to be put back on the road This next project hits one, combines two bikes from 2, misses out on 3, I am working on 4 and hit 5. Backstory - The G/S was as finished as I was going to make it, then I found the LS which had the Luftmeister catalog thrown at it.... got that as done as I am going to make it, then found the RS which had even more of the Lufty catalog used on it. The RS is in it's final stages now (at least I hope so), and will be getting sold (as much as I love it) as I just can't use three bikes that do something similar and my wife really prefers the R65LS. Knowing the G/S was getting sold, I put up a general wanted add on the /2 conversion Facebook page, and was pinged by an inmate here who I have been chatting with for years. He said he had a 1966 R60/2 with a 1975 R90S engine that had reportedly been assembled in Austin TX years ago. He had another /2 conversion, didn't need this one and a deal was struck. The R90S engine had a number of period hot rod things done: Briel sump extender, welded intake stubs, lightened flywheel, dual plug heads, intake porting, etc. Here are some of the first pictures I received: So, last week I rented a van and tackled the 2,100 mile round trip Played hooky on Monday and put the bike back together to see what I was missing. This is step #1 of the dry build Some things I discovered along the way: Luftmeister "high performance" clutch friction disc... well used I would say Holes for a blanking plate I am assuming Some of that period hot rodding Given the wear here, I am guessing that there wasn't as much engagement here as would really be ideal... I have the recent Vintage BMW Mag on conversions that details options to address this More hot rodding What's next? Well I am ordering parts from lots of different sources and will have quite a few boxes coming in shortly. Next, I am sure is more parts orders. My plan is to do a 100% dry build, including wiring and plumbing, then have any fabrication and repair done, tear down and paint (already have two possible colors picked out, and the options are not red nor black). Following the dry build and fab, while the paint is being done I'll tackle the engine and wheels - more correction I will have the wheels addressed. I need the change away from the 19" front and want to use matching alloy high shouldered rims on both ends. I will probably insert getting the motor running in there before paint in truth. For now the plan is to maintain the character and history of the bike, with the exception of new paint. I will be keeping the ATE calipers and (gasp) the under tank master cylinder as well (double-gasp). The engine and drive line will be cleaned and refreshed as needed (I have a Matt Parkhouse freshly rebuilt trans on the way now) and I will run the /2 final drive and swing arm for now as well. There is also a decent sized list of used /2 parts I will need, so if you have a stash please reach out to me and let me know. This bike really spoke to me. I am really happy to own it and am looking forward to this journey. *Update* A bit more on this bike's history - I purchased the bike from CA, the CA owner got it from a friend who had it in the NE, and that owner had purchased if from a guitarist in Nashville. The owner trail dies there as the guitarist didn't want to share the earlier owner's name. I also tracked down the builder of the bike who had an independent shop in Austin up until 2000. He built the bike, then bought it back (after the Plumber had an accident on it I believe) and then "rode it around Austin for years". He sold the bike in 2000 when he closed the ship, and it toured the country from there but the title never got out of his name, so I believe it toured as a project and not a runner. The builder said the bike came together in the early 1980's for a customer who was a plumber. The builder had purchased a large lot of R90S parts from another local racer (the builder raced an R100RS, and also won a race at Daytona on a Japanese 2-stroke of some kind). In amongst all the R90S stuff was Reg Pridmore's Daytona winning R90S, which he put back together and only recently sold it to Udo Gietl. The bike had the script "The Plumber's Bike" on the tank, and was at the 1984 BMW MOA rally in Missoula, MT and several members here remember the bike. The tank was loaned our by the Nashville owner and lost, but he still has the fairing. As much as I would like to have (not mount) the fairing, the cost of shipping isn't good. I'd also like to have that original fiberglass tank. IIRC, the tank was for sale on Craigslist years ago and I think I traded emails with the seller and only passed because it was fiberglass.
