I have a full Dyna system on my 500 and have no issues with low battery. Longest run was about 120 miles last year.
Hope the info helps

Very good work as usual. Had a few sets done by them.
Dropped off the last set and picked them up in person. Took at least 40 minutes to get away as I was chatting to the manager about bikes. He is really into his bikes.

Sprinta, did you fit a standard A10 first gear set or the A65 version? Both obviously lower than the RR box. Not been out on mine yet, so wondered what the RR first gear was like to ride on

Sounds like zinc or cad plate. I got a load of bits done at a local zinc plater and he just popped all the bits in a basket. A week later, they were all done. I asked for bright zinc, but it can be done with many different finishes.
Cadmium is poisonous and you are not recommended to suck on plated bolts  ;D. Believe it is also absorbed through the skin, so doubly dangerous

Good luck with the repair, At least you know its possible.
Had similar with a K1 750, working on the motor and found a load of epoxy resin around the front of the sprocket. Damage where the chain had popped in for a visit. I was very fortunate as a mate had a bit of Kawasaki case that could be made to fit and had it welded up by an FIA approved aircraft welded. Only cost me a case of beer too.

Thanks for the kind words.
For info a real RGS was made between 1962 and 1963, only about 1500 produced. BSA decided to build them after Eddie Dow built a few for his customers from Gold Stars. There was a demand for a more user friendly Goldstar. The BSA version had a different frame as it was marked GA10 and the engine was a super rocket. Loke the 500 Gold Star, the options available was huge. Suspect this was also a way of using up old stock as the A65 was introduced at that time.

Mine started life as a 57 500 Clubmand Gold Star, but sometime in the 60's the engine was put to use for racing. A 1960 Super Rocket engine was fitted as a replacement as per RGS. It does have the RRT2 gearbox and all the correct RGS parts. I bought it from my brother's mate who owned it for 35 years, this came for another friend who had it about 5 years and the next previous owner is also well known to my brother. They even know the chap who fitted the engine.

Brother told me it was for sale as the PO had become dissallusioned as he had completely rebuilt the engine and collected all the correct stuff over his ownership. He could not get it to run properly and had a couple of other Brits to play with. I saw it and liked it straight away. Found a couple of dry solder joints on the electronic ignition wiring and it runs really well, starts easy too. Waiting for some decent weather so I can test the dexterity of my feet and see if they can still swap gears and brakes as they used to.
