Might regret this but I do have a few pairs of genuine TEC points, I was keeping them as a just in case thing. If you want a pair Florence I’d be willing to let a pair go for £50 inc P&P. Pair means both sets of course. Some are still in bags or blisters packs, most are loose but you can tell a TEC set very easily. Checkerboard backplate and stamped with TEC.
Might be an idea to invest in the Hondaman kit as it essentially means the points should last for many years, so long as you remember to oil the felt pad.

Hi Ken , I have just seen your comments about TEC points and was wondering what parts of the points assembly are inferior and could you get a set of new pattern points and just fit them to the original TEC back plate ?
Ken4004:
I have a set of old TEC points which I removed from the bike during the rebuild and fitted replacement points because I noticed pitting on the faces of the points.
I did however have a little difficulty setting up the new points which were bought from DS, I had no problem setting 1 and 4 but seem to have difficulty setting up 2 and 3 because there didn’t seem to be enough adjustments in the slot.
I therefore assume that I must have done something incorrectly do started the setup again from scratch and still had the same result, I then decided that the points plate on the new points was slightly different so compared on against the other and all looked the same so I ended up just increasing the length of the slot for 2 and 3 points plate to get the correct timing.
All in all a bit of a mystery, what I probably should have done is just use the original TEC base plate and just transfer the new points over.
Has anyone else had this issue with lack of adjustments in the on points 2 and 3 ?
Oddjob:
It’s exactly as you found. Pattern points don’t like to time correctly on 2-3. The only solution is to reduce the points gap on both. That means less dwell angle that it should have. I think the heel on TEC points is longer, no problem with timing those. Plus the construction is far superior.
Ken4004:
Hi Ken , I glad it’s not just me, what do you recommend to set the points gap to in this situation ?
Oddjob:
Lowest permissible. 14 thou I think.
