BMW r 50/2 restoration project cape town
On the very last day of 2013 Mike and I began a restoration project on my beloved 1961 R 50/2 originally acquired from Westville Police in 1986 (I’m the second owner). My dad and I had restored the bike in 1987 but as I was in the army I missed most of it; managed to take completed bike to Kimberley for daily transport then back to Durban over Drakensberg. The bike has done about 25000 km since 1987 around Durban, Kimberley, Johannesburg, Port Elizabeth and Cape Town.
As the paint job was looking tired and with Mike insisting my slingers are gummed up, I am re-restoring and adding indicators and a back tray and headlight mirrors, maybe some more nice things to spoil it.
We found the bike to be in excellent condition mechanically and electrically, very little wear and tear (eg. throttle twist gears perfect, front electricals too) , testimony to quality of Bmw’s. Also have 99% of the original bolts, fastenings etc. Mike says this because I didn’t do any fiddly work on the bike; I don’t know if its a compliment or not.
As of today 10 Jan 2014 we have everything in separate boxes, parts for painting with Johnny what a blast…
I took friday afternoon off to visit Mike’s to tackle the engine. It took us 3 hours and lots of heat, pulling, some swearing and then its in pieces. As for the slingers they were less than 30% gummed up, so I win that one. The barrels have some strange motlings inside and one piston ring was stuck (5 per piston)………..I dont think they will pass Andy Johnstone test come Monday. (they failed; have to get first oversize)
And then we got to the carburettors on Saturday…….. and they are a mess; will have to replace jets , slides, floats etc and hopefully find someone to bore/sleeve/rethread main jet housing and idle jet housing ? The bike was running with one main jet completely loose !. The flanges to bolt to inlet manifold are curved badly, affecting suction. Various o rings and gaskets wrong……….how honest must I be ?
Saturday afternoon was spent cleaning with petrol, filing/sanding, then cleaning with brite acid on various aluminium parts. Now I have a box with parts to be cadmium plated bolts nuts washers , clamps all separated, parts for chroming, hard chroming, alum for polishing etc, all going to Glitterama also Monday and they itemise everything apparently!
Thomas came around earlier and brought out his encyclopediatic computer, showing what was cadium plated in 1961 (not the footrests), various original factory bulletins ! including one showing the correct indicator switch, manufacturing dates etc………the man is a mine of information, an expert on bmw’s
And then we got to the cylinderheads and we found 4 different valves only one being bmw, and the one valve was pulling back against its cotters. I have a list of over 200 parts to be ordered very soon
Paint : procured glasurit original avus black 086 from BASF Parow at R1.00 per ml and White for pinstripe , lot came to R 1460.00 only ! Its a base coat and clear coat going to Johnny tomorrow 18 Feb 2014.
First Parts Feb 2014 : Arrived from Bench Mark Works Sturgis USA (very small town) Vech sent them including set of Albert mirrors……….who says christmas comes only once a year !
My parts all R 31000.00 have arrived from Germany, with Volker in PE…….24 April 2014
Bike is painted at Johnie, but pinstriping is being discussed ! This after I visited Thomas and had to rethink it……….Thomas has a German hand painted tank ! (since 2007 not fitted yet ?!), pinstripes are big 4mm, gap 3mm, small 1.5mm.
