Reed Blades

On motorcycles, mopeds and scooters, you can replace the entire reed valve to get more power, but you can also simply repair or upgrade the original valve by replacing the reeds.

There are reed petals made of metal, fiberglass and carbon in various thicknesses. There are pre-cut reed blades for specific models or universal reed sheets that you can cut yourself.

thickness of Reed Petals

Simply put, the larger the piston, the thicker the plates should be.
However, you should also consider the operating speed of the engine. The more power the engine has at high rpm, the more we recommend thicker reeds. And vice versa, engines with rather low power speed need thinner plates.

Bad Reed Symptoms

When the reed petals are broken or worn out, it will affect the intake of mixture. The symptoms: poor starting behavior, unclean running at low rpm, the engine may even rev up by itself.

You can easily tell if the reeds are no longer closing properly by simply looking at them. Remove the reed valve block, hold it under a light source, if you see a light gap, the reeds are not closing properly.

Note: always make sure that the reed valve gasket is in perfect condition.
