Thanks for that, I'll check alignment as you say as soon as I can get the gear box something like bolted in place, awaiting some fixings to arrive.56G80S wrote: ↑Sun May 16, 2021 5:06 pm I ran an AMC box and clutch with a 1956 engine for decades and it was fine. I did change the spacer behind the engine shaft shock absorber, though the difference didn't appear to be much though.
Do pay careful attention to the alignment of the sprockets and avoid the primary and dynamo chains clashing; not good if they do.

Re: G80s box of bits
Whilst awaiting my parts arrival, I have pulled out of the magic box, the magnetos! I have a Lucas SR1 & a N1.
The SR1 has the auto advance fitted. I spun it with a battery drill after replacing the condenser and points clean, it sparked up but not very exciting. Did same With N1, it produced a big fat spark. Any thoughts on whether to fit the N1 with a manual advance or pay to get the SR1 rewound?

The SR1 is correct for your year and it's a better mag. I'd fit the N1 for now and get the SR1 rebuilt at your leisure.

+1 for the SR1, no experience of N1.

+1 for the SR1, no experience of N1. I would fit the BrightSpark EasyCap rather than the standard capacitor.

Re: G80s box of bits
Just rang a local magneto rewind guy who has quoted £250 as a ball park figure to completely refurbish the SR1,
Does that sound about right?

Re: G80s box of bits
I need a dynamo chain, there isn't one in the box!
The spares list have 49 link chain and 50 link chain but I'm struggling to work out what I need for a 55 G80, any ideas?

Re: G80s box of bits
It's worthwhile familiarising yourself with the Spares list for your bike. See page 19 here:

Yes.
