Dismantle the filter using a screwdriver.
At the air suction area, remove the extending
suction limiter. You can do this with the help of a cutting tool
such as a saw or angle grinder. Sh Performance prefers to do it
with a Dremel or a heated knife.
Next, clean the airfilter thorougly and make sure you sand the
entire airfilter and don't forget to deburr the edges.
You can replace the original screen filter with a foam filter
for maximum suction. You could also simply use the original screen
filter or you can use a needle-nosed pliers to remove some mesh
layers which results in more air passage.
Before you reassemble (the now modified) standard air filter, make
sure you don't overlook any dirt (very important!). Once
you're sure it's clean, reassemble the filter.
Why would you modify the standard original airfilter?
On the stock Puch Maxi mopeds multiple limiters are often added.
One is in the air filter. By modifiying this, your Puch
Maxi will have more air passage and can result in a couple of
extra km/h. Do note that when you modify it,
you should also adjust your carburetor jet since the mixture of
fuel & air needs some adjustment.
Next to the extra airflow another nice thing is that your Maxi
keeps its original look and you can still use the side covers (meaning less trouble with the police 😃). Modifying
it does make your bike a bit louder, but less louder than using a tuning filter
