On this page we will discuss how you can define the right
heatrange of your Spark Plug for Puch Maxi Mopeds.
DEFINE THE RIGHT HEAT RANGE
Defining the right heat range of your spark plug is essential for
the good performance of your Puch Maxi. The general rule I love to
use is, the more rolls per minute, the colder the heat range needs
Which heat range your current spark plug has, is always mentioned on
the spark plug. However, each manufacturer uses it’s own way of
defining the heat range.
In case of the NGK spark plugs, the rule is:
the lower the number; the hotter the heat range
the higher the number, the colder the heat range
In case of the spark plugs of Bosch, it’s the other way
the lower the number, the colder the heat range
the higher the number, the hotter the heat range
PUCH MAXI HEAT RANGE TABLE
After doing a lot of research and asking a lot of Puch experts
their opinion, we created a short tabel with the type of cilinder,
the heat range, the brand and the indication mentioned on the
spark plug. This will help you a lot to define the right heat
range of your Puch Maxi.

IS THIS REALLY THAT IMPORTANT?
Yes! To show you the importance of it, I will share you my own
A few months ago my Puch Maxi was having troubles at full speed.
When I was driving at full speed, my Puch maxi made a ‘stuttering’
sound. Really bizar and probably not good for my beautiful lady.
This was during summer and autumn. When winter arrived and the
temperature dropped significantly, my Puch Maxi didn’t even start
anymore (drama!). This came as a big surprise, because my lady
always started in a few seconds. So I tried several things… But
the problem only disappeared when I defined the right heat range
and I changed the heat range of my spark plug. And guess what, my
Puch maxi didn’t start because of the fact that I was having the
wrong heat range! I replaced it with a Bosch W8AC (which is a warm
spark plug) and it started immediately. In addition to that, the
stuttering at high speed was also gone. So yes, to define the
right heat range is important :-).
Don’t be stupid, do the investment
After doing a lot of research, I noticed that a lot of people
experienced serious damage to their engine because of not using
the right heat range. So don’t be stupid and spend of a few euro’s
/ dollar’s on the right spark plug and avoid this kind of trouble
now or in the future. If you define the right heat range of you
spark plug today, I can guarantee you that you will avoid a lot of
common problems and solutions
