I had another one of these follow me home this weekend . . .





Fortunately, this one is not mine, but I will be restoring it for my good friend, Dan, aka BritTwit. This is a numbers matching '63 Goldstar Twin, despatched to Hap Alzina on 6/20/63.

Dan had accumulated many parts and a significant amount of information on his bike to provide me with an excellent starting point. This will be mostly a photo documentation of the progress, and as always, any and all information and comments are greatly appreciated.

Dave

Looks like a good restorable machine.
Do you have the correct fenders, fuel tank, cylinder head etc ?
I am looking forward to see the progress of your resto.
Good luck bigt

So you let Dan talk you into it. You must of got him to throw a few more parts in. Now that you're in the resto business when will you have time to finish the T100R?

I'll be one of those who will be following your progress on this.

Thanks, Peter. We do have the correct tank, fenders and head plus a pretty good stack of NOS parts. The tank is in pretty decent shape and will be sent out to Ross Thompson for proper reconditioning. The fenders are older reproductions but very nice.

Bill - I have finely honed the art of multi-tasking. I have learned this skill from my wife who is in IT management. With as many projects as you have, I think it's best for you to just send me your T100R and I'll go ahead and restore that too.

Magnetoman - Compared to my RGS, when I started that project, this one is relatively complete.

As for my progress so far, I have a severly seized engine. I tried slowly heating the cylinders with my heat gun and it melted, so I tried the Swan approach . . .



I did not succeed this evening, but with everything I've learned about British motorcycles, patience is key.

Until next time...
Dave

Okay, I'm spiting out crow feathers. My T100R project is definitely more complete with your help, that's for sure. I had a friend over today to look at the BB Gold Star and he wanted to see my next project! I'm still mowing grass from the two weeks I took off for the rally.

Well, it took a week, but it is finally unstuck. A mixture of acetone and ATF and a couple of hours each night with a heat gun, it finally broke loose today.



Right side piston was the culprit. The rings are locked solid to the piston.



This machine and my RGS both have this inner primary, it is the short-tailed, not drilled for the chain guard, but there is a casting mark where the hole should be drilled. I was told several years ago that it should be the long-tailed inner primary, like the Goldstars. Have any RGS guys had any experience with this? These were both west coast bikes.



Until next time . . .
Dave

I went and checked and FWIW, my two West Coast RGS's have the same inner primary as yours.

Thanks for checking that, Bill. Four RGS' with the same inner primary is enough proof for me. I spent quite a bit of time, Saturday, doing the final teardown of the bike and running some stuff through the parts washer. The engine cases and gear box are in excellent condition. . .looks like they've never been wrenched on before. The headstock of the frame looks like it has a bit of a tweak to it, and I will cover straightening the frame in an upcoming post.

Like I mentioned before, the frame has issues.



I spent several hours at the shop today building a jig and moving the frame around. I have achieved 27 degrees rake again, but I might still have a little side-to-side tweak. I will need to reassemble the chassis to check alignment. I have about 20 tons of moving power, way more than this frame needs, but these BSA frames are strong frames.













I also discovered that the inner primary is extremely twisted. Has anyone had experience with straightening cast aluminum?

Well, Brett, I've straightened a handful of motorcycle frames at the shop where I work. We are right across the street from a large Kawasaki/Honda dealership and we do a lot of straightening of ATVs, same, but different. Shoot me a PM about what you have and how bad it is. It can get pricey though; the frame machine I'm using is a $30k machine and the shop rate is $75/hour and the RGS frame took 6 hours so far.

Yeah, Fred, I assumed that the center stand was not right, but luckily the center stand mounts aren't broken off like mine were. I will have Dan contact you about the inner primary, he has someone that thinks they can straighten it.

Paul,
Next time you're in KC, shoot me a message, it would be nice to meet you.

Just like the RGS' began, a Super Rocket engine in a Gold Star frame



I was actually doing some repair on a Gold Star frame today for Dan that had the trans cross members hacked out of it and all I had was the RGS engine to line it up.







More on the RGS soon.

I posted this on the BSA Forum but thought I might post here as well.

As the parts manager for RGS Dave's current project, I need some info.

I have the following RGS related parts bulletins.
G21 April 1962
N8 August 1963
Is there anything else out there that I may be missing?

Yes, there's more. For example, there's an October '62 G21B that has ~15 parts that are ones that differ from those on G21.

A few weeks ago I started (and then stopped; but will start again) to organize my fairly large collection of bulletins, service sheets, etc. While doing this at the same time I've been photocopying everything that mentions either a G.S. or a RGS to have in separate folder. Realistically, it will be a few weeks before I get back to doing this, and some time after that before I finish.

So are the bulletins G21 and G21B East coast related? I have what I think are a complete set of bulletins from that period and only have the N8.

G.21 doesn't give any indication of East, West or otherwise, but G.21B's title is "A10 Rocket Gold Star (U.S.A. West Coast)."

Good news on the inner primary. I remembered an old tech tip I read in "Twitter", the old Gold Star Owners Club news letter.
Cleaned up the threads with a 1/4x20 tap and cleaned up the screw holes.
Bolted up an old outer primary cover with allen head cap screws and torqued to 25 ft lbs.
Oven baked at 400 degrees for one hour. Let cool. (frosting optional)
What was one a 3/16" gap in the middle is now gone. I test fitted my NOS outer primary and it now has a nice fit.
Clubman tank is on its way to Ross Thompson and then on to Brown's Plating in KY.

I finally have some updates on the RGS.



I have the frame where I want it to be. It was a little more work than expected, but now I can move forward with the restoration. With the engine and gearbox in place, I have mounted the siamese exhaust for fit and it far exceeds any after market exhaust.



I just don't understand why anyone cannot make a decent exhaust to fit for the price charged on after market pipes. Below is an example of after market pipes.



Here is one thing that you won't see on an Armour's pipe:



It actually fitting!

The project should progress a little quicker now that I have everything aligned.

I'm enjoying following your restoration and look forward to your future posts. Your work on measuring and correcting the frame is especially interesting since most people seem to assume all is OK with the frame. As tweaked as yours was some people could have overlooked it, and even quite a bit less deviation than it had could have caused some "interesting" handling issues.
