R-90 S mirrors

There are ways to determine originality. Shape and flat black paint are indicators. A real give away indicator on original mirrors is the copper -based brass or bronze stem material. If a scratch on the paint reveals copper colored base metal, its the real McCoy. Marriott 1975 R -90 S 1951 R-51/3 1...

Ethanol-Chemically harmful

Our horizontal twins and singles are made of mostly metal and rubber-with a minimum of other products. The engines were designed to best function and run reliably on pure gasoline. They were NOT designed to run on alcohol or alcohol by-products. Gas lines are adversely affected, steel tanks will ru...

Parisian French- Vintage motorcycles law

According to a reliable military source of mine: The local government of Paris is considering/implementing a new law barring motorcycles older than the year 2000-from entering the city. If this is confirmed, it creates a hardship on owners. This fickle law also ignores an existing ordinance in Paris...

Brown-Van Farowe

If your bike is not heading to concourse gatherings with judges, there are other options. The Brown and Van Farowe side stands are the way to go from a functional perspective. I have them on my /5 through /7 bikes, including a black R-75/5 Toaster. They are very reliable and eliminate the weaknesses...

In its history-a few 69 S bikes were known to self-destruct pistons. Craig Vechorik has seen my 69-S. It is all-...

Del Ortos Leaning out on Curves

On my 1975 R-90S, the Del Ortos seem to lean almost bog a bit on curves. This may just be when the engine is not at fully warmed up or hot from a long run. Particularly noticeable on first few hard curvy turns.... Does not occur with a 77 R-100S with 40 mm Bings. Has anyone else encountered this pro...

R-51/2 Engine

There are some small differences. Same dual chain-driven camshafts. Check with Richard Sheckler-who has had both pre-war and post-war R-51s and knows their intimate mechanical details. Crank pins and spacers. His email is: rishelaverne@hotmail.com
