    Plus, ensure the clutch centre nut is tightened to a torque of 65 lbs/ft to eliminate clutch drag.

    I agree with Julian. Its difficult to quantify unless you know exactly what is required, some engines need next to nothing done some need major refurbishment. I realise you consider SRM expensive but here's a link to their 2016 prices which should give you some idea of costs.

     New vehicles are subjected to a drive by noise test. No limits apply to motor cycles or mopeds first used before 1 April 1983.

    I don't think there are any specified.

I use the A50/65 setting which for the 9/16" BSC, 20 TPI. In the 60's it was 28/30 lb/ft and changed to 35 lb/ft in May of 1970. Not sure which bolt length you require.

Hi Bill,
          its these you are looking for:

Alternator rotor 2.85" bore 19-8017

Stator 6v RM19 2.85" 19-8016

Maybe worth checking here:

It gives measurements to enable you to check.

Twins / Re: Indicator buzzer
« on: 05 June, 2019, 20:39:50 »
    I have fitted LED indicators, E marked which are successful. I didn't use a buzzer as with a close fitting helmet and exhaust noise I thought it would be difficult to hear.

You can purchase auto turn off relays such as above which work with momentary or normal rocker switch. The E marking and relay option is not cheap but I feel safer on the road and it suits my bike. If you want pics let me know.

Hi and welcome to the forum,

DC - The +ve (mounting stud, positive earth) to the frame. The -ve to the battery (could be via an ignition switch and ammeter).

AC ~ - Two wires from the alternator white/green and green/black to the other two connection on the rectifier.
Three wires from the alternator white/green to one connection green/black and green/yellow to the other.

Hi Mike,
            Whats left in my garage  ;).

If purchasing I use thin wall 16.5 amp with a blade fuse 15 amp, say:

These thin, flexible cables carry a high load with good abrasion resistance. I insert into black braided cable sleeving finishing with heat shrink.

Hi Mike,
            I have a fuse box on my A10, it took some thought. I have a lot of technology on the bike, the wiring colours were not BSA so thought it was worthwhile. There was a digital voltmeter alongside but it was faulty, waiting on a replacement  >:(.

The coils I used are:

I fitted this one to a A50 and found it neater if exposed:

Hi Splodger,
                  I always use oil pressure gauges where possible. Here's what I've got on the bikes at the moment:

Hi Mike,
            You are most welcome. Note: If you use the original light switch you don't need the diodes

Best regards...

    Looks like you have  a snakes wedding there, I simplified the wiring to this:

    Most electronic tacho systems using a HT sensor can be set up for single, double, triple coil or wasted spark ignition systems up to 12 cylinders.

What are the wire colours?
