I have attached a photo of the factory reed next to the reed I installed.There is a difference in the size of the intake so that more air enters and I have more compression.With the first start the difference was immediately apparent having a 17.5mm carburetor.When I put 21mm it will be even better. The compression is higher and it works very fast.

Both the materials used and the accuracy of manufacture of the purchased diaphragm valve are at a really high level, and this is one of the most important components of the engine. Accurate labeling of the model on the package by the seller did not allow for a possible mistake in installation. After installation, it works without any problems, so I can in good conscience because I can recommend it.

These baffles are as I wanted them, thin to achieve quick reset and sealing of the intake resulting in better cylinder filling. Very good product.

Ideal for budget tuning fit for minarelli horizontal you don't have to spend a bunch of money to have a diaphragm valve that doesn't go into resonance

Leaves ok, in my case, unfortunately, minimally stand off.
