Really nice looking bike. Mine's a '66 (or 67) N15CS I got in a pile and it's now in the last 10% fun time of the build, I just went stockish, found some NOS .040 over low comp pistons and had the spigots milled off since I had a good cylinder head from a later model. My spigot cylinder head had stripped exhaust threads so it seemed the right way forward and has worked out, it's back together and spinning nicely with reground crank, cylinder head refreshed etc.
I got a Tri Spark with some parts, won't work on my bike as it's wrong direction. Maybe someone will want it, appears new but who knows. I have heard the instructions are lacking. I have a new Wassell unit and a special housing, and new coil. I didn't feel like shelling out 2x the $ for a mag rebuild, regardless how 'cool' it is. I hope I'm up to the task of getting it sorted, will see in a couple months when I have time.
