lot of the life is how much current is used and at what voltage

the term to look at is Dwell how long the points are closed and the coil is powered

and how is the quality of the capacitor

link is for 12volt systems

A few variables here I would say - has the little felt pad being been kept lubricated.

If not then in theory the heel of the points might wear quicker.

Are you using electronic ignition? if you are the current through the points would be greatly reduced so the points would last longer.

I would say, given how much points cost, any doubt just replace them, but then again the old addage applies "if it aint broke dont fix it"

And at last it depends on which contact breaker you use:

-"Normal " original
-Original with "Pertinax" material
-Reproduction

I've only replaced it on the MZ once, and that was because one of the contacts on the points fell off one day. The only discernable difference that made to running was a wavey idle.

I have replaced points on my car once too.

Lets make it simple: The contact brakers last as long as they last.

If I should make a "hit-parade" of the parts:

1.Pertinax
2. Normal Originals
3. Reproduction.

The exact time or mileage depends on so many circumstances that it is impossible to give an exact answer ...

I would say anywhere between 15-30 really..

My last set lasted 20k if they were the original set. And my current set I have on now is at the 10k mark almost.

So, I think it's possible to get to 33k..

Sorry, but I don´t understand the use of such a discussion.

There are so many influences to the lifetime of a contact breaker that you cannot predict its lifetime.

If it is worn out, I change it. No matter how long it lasted...

Or change to an electronic ignition :-)

We all can be lucky if this is one of our biggest problems with our MZ bikes :-)
