Magneto back and installed

Thanks to Doug Wood for a magnificent job restoring my Lucas K2F. Just got in back Friday and my 59 T100 is running perfectly again.

My first attempt at timing a mag bike... A bit tricky but all went smoothly.

I changed my mind and spent the significantly more money to stay stock. I will be posting a Thorspark Electronic Ignition for sale.

Ya that is my ultimate question at this time. Mag vs Points. Hard decision for me to make though on my 1965 650 T120R.

Not hard at all.A magneto will cost you more,and deliver less.It will have one set of points,where the standard points system shares the wear between 2 sets of points,both with independent timing adjustment.
Not so easy to correct timing differences with a mag.

There is often little or no advance curve with a mag.With the AAU on the standard points system,you can adjust the advance curve by changing or adjusting springs.You can get full advance at any rpm you like.

Don't use the original '65 AAU and breaker plate.Use the '67 onward AAU (different dwell angle),and a 4CA or 6CA breaker plate.
