Now that I finally had my rotary valve tuned by Stefan Teutrine, everything is running even better.

What I learned: The rotary valve should definitely have a 0.05 mm gap; then everything tunes perfectly.

It now goes from a standstill to 120 km/h. Totally smooth with plenty of torque... a dream.

The 22 mm sleeve is amazing; I had it on a 24 mm before, and 22 mm intake is significantly better.

Hi Andreas! I wanted to give you some feedback, as I'm really impressed with your carburetor and have already recommended you to many other tuners. Some have even ordered from you as a result, Chris P……., for example.

I have your SI 25 on a VMC 252 and drove to Elba and back without any problems! That included some highway driving and long stretches of high speed. The carburetor always got enough fuel and worked perfectly.

I'm happy and will definitely order again; I'm fed up with reed valves 😜

In total a better torque. Noticeably better performance at the most important sector between 50 and 75 kph.
All of that without losing at maximum speed compared to a regular 24 mm carburetor.
