I'm looking for some good quality points, preferably ones with the tufnol heel. I have a twin point twin coil ignition setup on the Vincent which uses Norton Commando points. Until now this system has been trouble free for the 25,000 miles I have ridden the bike. About two thousand miles ago I replaced the points because the existing ones were getting quite pitted. The new points have white plastic heels.
The heels on the new points are wearing and causing the point gap to decrease. This in turn causes the bike to stop firing on the front cylinder until the gap is reset to a minimum of 30 thou. I know this is a very wide gap, but it is required with this particular setup.
The old points also had white plastic heels, but the plastic must have been a much longer wearing material, wear on those was minimal and never caused any ignition problem. I've heard that the very best points are those with the tufnol heel, tufnol being that red-brown material which is made from linen , which is made from plant material (flax)
