[QUOTE="ksbundy, post: 54547, member: 714"] I run a triumph points set up on my racer for many years. It was fixed timing with no advance. I machined up the housing and shaft to take the triumph points plate and cam. Just shifted the mounting holes on one set of points, around 25 degrees. I think I had to grind a little of the points base to get clearence. I ran Yamaha 12 volt coils mounted under the seat. The only problem was that I had misfiring problems with the condensors beside the coils, I ended up mounting them on the cap of the points cover and the problem went away. System went well and started very easily with 12.5 : 1 cr with GP's on methanol. Just ran a battery which had sufficent charge for practice and 4 or 5 races (depended if you got into the final). I ended up converting a points plate for my brothers racer after he had problems with a magneto. He used the housing of a Norton Mercury which fitted straight up. I also bought a similar setup from a chap at a bike show at Stanford (I think) it was for a single, but could be easily converted to a twin points plate, I will have to have a look and see if it has the advance mechanism in it, and in which direction it goes.
