I thought you Goldstar guys might appreciate my 1953 Alloy BB34 with a 33 Norton girder. It was specially ordered by Hap Alzina and raced in the LA area in the 50's. Supposedly, they were dubbed "Goldstar Specials". This weekend it took the trophy for Top European at the Born Free show. I know it's technically not a Goldie, but with it's stock high compression alloy top end and close ratio gearbox it's damn close and even more rare.

Sweet looking machine.

Do you know what it has in the way of a crank? It could well be a full GS bottom end and not the B34 crank with the small drive side roller. I have a 1950 ZB33 Alloy option engine and it was built with the full GS crank set up but only stamped as a ZB33A. What letters are stamped on you cases?

Thanks guys. I really love this bike, I just don't know too much about it yet. The bike isn't in front of me right now, but I know the motor prefix is BB34.A. with H.C. stamped right by the vin, and the frame is BB32S. Trans is stamped "CR1" I have a Goldstar book that confirms both numbers as 1953 and curiously they both end in "40"- maybe just a coincidence. I don't know what crank is in it, but a few Goldstar guys have said the motor (and frame) is Goldstar from top to bottom, except the VIN. I guess even the head is the same. When I got it, it had telescopic forks with no headlight ears on the covers, and a 7" brake. It has a 10TT9 on it now, but it had a 289. If anyone can share anything else about this machine, I would be very appreciative. Also, the magdyno seems to be on the fritz, and I have one I removed from an M21- will it work?

Also, I just won a pile of old "Twitter" Goldstar Club journals on Ebay, so hopefully they will have some relevant information.

The M21 mag should work even if the HT lead is on the front as the BB small fins should allow enough clearance.

Thanks Gormo- I just checked the magdyno from the M21 and the HT lead is on the back and the tag reads "MO1L L1" made in March or '54. If I remember right, the M21 was a '56 meaning this may not be the original mag anyways.

Ray- I sold some unit Triumph parts to a kid in LA a while back, and later, he offered me this bike in exchange for some parts and a few bucks. It kinda found me. The Norton girder came from Canada- it was on the BCS classifieds a few years ago.
