Hi Johnny,

Does anyone have an address of a reputable Home for the Bewildered? 

Looks like you found it here

John

its blue box, the exact kit you have kindly shown, the exact same coils etc

You say "coils"? I assume you mean the single dual output coil as shown in the picture and not two separate single output coils?

If you do actually mean two separate single coils then how are they wired?

the modern type regulator/rectifier dosent seem to have a makers name on it, these modern add ons are all a good idea but bypass the makers manual,

Does charging system appear to be working normally? Have you checked the voltage (both battery and charging)?

another thought is could the earth on the coils be maybe not good enough? as they are not earthed direct from the fixing because they had to be cable tied to the frame and couldn't be fixed to it,

According to the Micro-Power instructions (below), only the (+) terminal (of the dual coil) has to be earthed (the coil body is plastic) and only if positive earth.

yeah duel output exact one in the pic, and it has a new battery that charges fine, also its wired same as the makers diagram positive earth

Wow, that's quite interesting, Hughie. I hope you'll manage to track him down. Do you know anything of the history of the bike and how it got into your hands?

I have a Triton with a Triumph T110 engine, which has been modified with a Nourish / Weslake 8 valve head and 920cc barrel. I had the engine rebuilt and as part of the refurbishing process fitted a new central oil tank. I realised that the new oil tank didn't have a restricted return pipe which provides back pressure to drive the oil to the rockers (T'd off the oil return line). To get around this I decided to feed the rockers from the pressure gauge tapping on the timing cover, adjacent to the pressure relief valve and has the advantage of feeding filtered oil that has been cooled in the main oil tank. This operates at high pressure so I fitted a restrictor into the feed line. This all works well and I get a good supply to the rockers.

However having run the engine in for around 1200 miles I've come to the conclusion that too much oil is getting to the rockers (various symptoms) and so I'm considering going back to the original scheme of feeding the rockers via a T off the oil return line. I've also fitted an oil filter into the oil return line so this will give me some back pressure but I'm considering putting a restrictor into the oil return line.

Does anyone have a view on the size of restrictor I should fit. Due to the design of the oil tank its not possible to crimp the end of the pipe and drill a small hole in it like many factory bikes have.

Best regards

Yep, the last jumble I went to (about a month ago) had several stalls with boxes of old spanners on the floor in front of the table. Some were those flaking-chrome things but most were the older pre-chrome-vanadium heavy spanners of fifty years ago.
Probably could have picked a good range for a fiver, and rather negated the idea of "this metric spanner is close enough".
