Goldstar main bearing question

Yesterday I fit the crank into the cases and they fit up smoothly. The drive side is my question. It has two bearings. The large two piece bearing fits up next to the crank.
I shoved the inner race and rollers right up next to the crank cheek. The outer piece installed into the left case. With a little fiddling the two sides of the crankcase came together and after bolting, the crank turns over easily. HOWEVER...upon peering down into the case on the drive side I see the inner race has not made full contact with the outer race. I see the bearing rollers sticking out a good 1/8" or more. It appears I need a spacer between the crank cheek and the inner race but I have no recollection of such a thing. Ideas? I've always run the inner races right up to the crank cheek on other motors.

On the B50 which uses the same setup there is a spacer

Suggest you look in the parts lists

If anyone has a goldstar motor apart can you give me the dimensions of this part? I will make one on the lathe. Is there a Goldstar shop or expert in the USA?

Doesn't John Maloney at Autosport Seattle own BSA motorcycles?

problem solved. Yes he has more than one Goldstar. Haven't talked to them in a while.
Anyone have a spare DBD timing cover?

Always good to make progress.

Little off topic: John has got my P11 barrels. I went to John on your advice about who to see in Seattle about Norton machine work. He and I did not see eye to eye about what I want done. I left the barrels and I hope he follows my directions and doesn't go off script.

what was the difference? They should be standard Norton barrels, perhaps a different honing finish? He told me he would hone to suit. I generally take his advice.

Really want to know?

He was pushing surfacing the barrels without ever looking at them and didn't want to listen about the bore size I need for the pistons I am using. The barrels don't need to be surfaced. I had to make him check them while I was there, since I already knew they did not need to be resurfaced. My squish band is very thin on this build as it is. If resurfaced, I'll have to get a thicker head gasket than what is planned. I took my pistons to him with notes from Jim Schmidt to get him on board with the bore. I'm hoping that helped. Then again it may have just pissed him off. He's not accustomed to working with people that know what they want and don't need to be told what they need.

Hone to fit will get you out of round bores. Just saying
