Update

I am not so happy to say that I still have the problem of the flashing charge light. The light is on a low revs like normal and when you give throttle the light flashes internittently and speeds up as you increase throttle. I have rewired the bike in its entirety so I am sure there are no grounding issues related to the wiring. I replaced the regulator with a NOS original bosch regulator with the intention of keeping the bike as original as possible so I don;t think that the regulator is the problem. I have replace the wiring harness, the terminal plate in the headlight shell, the terminal plate in the generator, the condenser, and the brushes. I tried the trick of repolarizing the regulator by touching the red wire briefly to the blue. The coils in the generator are continuous and as far as I can tell the rotor is not rubbing the stator.
Link to Electrics Installation
I have read Allan Athertons and your story Richard, over on the yahoo mono lists, and it seems to be the same story. I am loath to blow a load of money on a new armature, coils etc. and am now thinking of going down the 12v route as I want reliability with this bike. I want to be able to ride it when i want. It now looks great, the engine sounds great so far (not yet ridden yet tho) and I want it to be a rider, not a show piece.
I would appreciate any possible remedies and also views on the 12v powerdynamo installation.
Many thanks.
James

James - Where are you
Where are you located? It seems like this ends up being the go-to answer (I'm pretty weak on electrics), but what about touching base with Vech? Someone else had an issue with his R51/3 suspension and Vech answered an email. Worth a shot to see what your options might be...
Allan has pictures of the 12v install on his website. I know someone who went to the system on his R60/2...different than the single cylinder, but he likes it.

Fast. Neat. Average. Friendly. Good. Good.

As an aside, I just came across a R90S for sale that would make a lovely "next" project!

And yes, get the R90S.

Oh no, wifes coming home- get the engine out of the oven!

Video of the problem can be
I had changed my order once I found the NOS regulator and cancelled the electronic regulator. Anyway, I got on to Uli's today and ordered a new electronic reg and a nice pair of metzeler block C's to finish off the project nicely. I really hope this solves the problem as simply as yours got sorted in the end. I will probably end up going the 12v route if it is still an issue. It would be unjustifiably expensive to replace the generator, particularly when I want this to be a bike that can be ridden. I'll keep you posted.
The electronic regulator
I polarised the generator and then disconnected the battery and installed the new unit. It now seems to be working without any issue. I couldn't take it for a ride as new tires are being installed but everything seems to be good now. Hopefully that's the end of the problem and I can go cruising!!
Thanks for the previous advice all.
