B29 Tappet Covers
« on: 10 Aug 2018 at 18:54 »
Looking through the archives, someone mentioned back in 2004 that the London Douglas club may have these.  Does anyone know if this is true?  If they do, is there any way for someone in the USA to get a pair of them as the club says they will not sell to North America.

It looks like I am going to try to make some myself.  The question is should they have slots or should they be solid?  I've seen pictures of actual bikes with both, and the sales literature shows them to be solid.

I have the same problem with my 1930 H3.

When I got the bike, it had only a few original engine parts left.
With these parts came 2 different Valve  Covers.
I believe the slotted one (it is casted alloy) is the right one for the year.
The front is slotted, It is only on one side closed,the other side is open. May be it is modified?

I think the B29 has the same covers.

Thanks Michael, good detailed pictures that show how complicated the slotted ones are.  Looks like I will probably have to go with the unslotted design if I make them myself.
