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.

I own a 2010 Keewey Hurricane 50 scooter the item fits the engine but does not fit in the frame of the game will mount a larger carburetor, the item comes with 1 gasket when there should be 2 included for this has a slight minus with me and yes it is great.

Benelli 491 98r Valve in working order without any defects or sharp edges Construction is polished hard plastic, contact surfaces are elegantly sanded evenly, plates are quite hard I think this will prolong the life and at the same time strengthen the machine.

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.

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