Is there a goldstar expert in the USA?

I have CB cases and a DBD crankshaft. Will it fit with no problem?
The timing cover is the quill variety. In Pearson's site he offers the service or sells a new timing cover. Anybody know how to do the modification? Perhaps I can do it myself. I did not get a response from my email to Phil Pearson, is he still in the Goldstar bizz? Sadly, a lot of these people such as OB and Phil Radford have retired or passed on.

Phil is still in business but I believe he is taking a break due to his wife being ill IIRC.

And he‘s seriously in demand. So I wouldn’t rely on him for remote FOC email advice !

Tom Heyser from Heyser Cycle in Laurel MD used to do a lot of dealings with
Jan de Jong from ABSAF in the Netherlands

Tom does know a thing or 2 about Gold Stars himself to .

or you could try Ken Rosevear but he is from Ontario Canada

I talked to Frank Diehl about this , he has timing covers. He can order one probably from absaf. That would be the best way to go. My MONSTER problem is worn bearing holes in the cases...by the time it reaches 120 degrees all three bearings are ready to fall out of the cases. I am in the process of wrapping the bearing in shim stock which I have been successful at so far but installing the crank carefully is a two man job and my helper is not available very often. Plus...making three bearings align while in sloppy holes is easy. Now they are shimmed and hopefully all in a row to the thousandth. Maybe. Will find out on the 20th.

@seattle##gs

How about putting the cases on a mill centering on the bores and boring them out and shrinking bronze bearing seats in there?
Or else i could imagine one could weld the original seats up and bore them out new, nonetheless i have the suspicion that during time one might have some relieve distorting due to welding in the bearing seat bore.

The bronze seats i imagine, would be a challenging although doable job.

kind regards

I tried that in the 1980's on a main ball bearing, after a few hundred miles it was not feeling as good as when first run, dropped the sump plate to have a look and found assorted pieces of shim stock loose in the bottom of the crankcases. Never tried it again, Loctite did not work either so now its either copper plate on the OD or new housings.

I found a place locally called FLAME SPRAY that would build up one bore for $350. The main problem is the left case...the outboard bearing is really loose and the inboard bearing could use a thou or two build up. The big problem is what to indicate off of when the metal has been built up.

Choose one hole and make that the datum, bore that hole to size first and then line bore off that finished hole to the rest, best to choose the one currently nearest to size.

I have a very skilled machinist friend, it's time to get hold of him again. Won't be cheap but better than new cases.
