Reinforced Passenger Peg Muffler Hanger tab on BMW motorcycle

This is one of those things I try to do to every BMW motorcycle I rebuild.
This area is cracked on nearly every frame I tear down. It is the rear foot brake area which also is the muffler / silencer hanger, and where the passenger foot pegs attach. This frame is a 1978 BMW R100s. If you are considering rear sets on your bike that attach to this section, then I HIGHLY RECOMMEND doing this procedure.

New piece of metal to weld onto the old cracked section to reinforce the area making it MUCH stronger and no longer prone to cracking.

Just an update… I have 3 bikes in the works but they have been taking longer then expected.  I’m trying to customize many features vs buying the available parts out there.
And, I’ve been busy over at Oshmo.com helping to develop some Airhead aftermarket parts that look good, and function, for customizing these old BMW’s.

Recent additions are rear sets, and top clamps…  more ideas to come!!

Ed Korn Cycle Works Swingarm seal removal tool

Removing these seals is a frustrating process.  Prying them out usually doesn’t get you anywhere.

I bought Ed Korn’s tool a while back and it can be used for pulling both the races, and the seals.

Here is how you use it to pull the seals.

Here is the tool assembled

I first cut out some of the seal’s rubber with a razor blade.
It was easier to get the tool installed that way.

Then you tighten the threaded rod with the allen fitting at the end of it.  By doing so, it expands the nut against the screws and presses them outward so they ‘catch’ under the metal part of the seal.

Then you install the collar, plate and washer and nut.

Once you begin tightening that nut, it will pull the seal out into the collar.

You can then loosen the nut, and break the old seal free with a few taps with a hammer.

The new BMW R90S Concept bike

I was just having a conversation with a buddy 2 days ago about how BMW should ‘remake’ one of their old bikes.
Triumph did it with the Bonneville. Ducati has the Paul Smart bikes (which i love).
Well, here it is. The homage BMW R90S.
The original R90S is a true classic.
While the new bike looks amazing… i fear that it looks too much like a new bike and not enough like a classic.
Of course, i’d still love one in my garage….
