Great to hear another A comet.
I have done 11000 miles on mine in 10 years ,.Conways did a total rebuild on it , A couple of things have gone wrong ,mostly my own fault , but over all a great machine ,and I live at 8000 feet in the mountains ,so down a few HP up here.
good luck getting it going.
A couple of mods I have done is
1. a sealed bearing on the engine output shaft to the chaincase
2. sealed bearing on the output of the gearbox.
If you need any help you can email me.
