Title: Wanted. 1933 B33-2 primary chain cover / guard.
Post by: Makitalo on 01 Jul, 2026, 13:16
Hello

Looking for primary chain cover for my B33-2. I think it is 1933 only design with primary chain and magneto chain both in the left side. As far as I know this design has the outer part only.

If I cannot find one, I think I have to make my own replica. So if you have one, but you are not willing to sell, it would help a lot if you could take some measurements and/or pictures from the item.

The pic shown is stolen from the net.

Kind regards
J

Yeah, that seems to be the (only) way to go. Would like to get measurements from an original one. Seems that it is difficult to even find a person who has the original part. Of course it is somehow easy to make a working item, but with the same effort, could make one w/ correct dimensions.
Maybe in Veterama there is a dude from Poland who has a truckload of these for sale... 😁
