Parmakit SP09 - Strohspeed - PWK33 - Big Bertha

Sven Kauke presented his current project to us on Saturday.

A very successful concept in our opinion!

The inner values ​​were then checked on the test bench. To explain, we would like to add that the cylinder itself has not undergone any revision, so it was plugged onto the engine as it is delivered by Parmakit.

In this case, the measured control angles are 128 ° / 190 °. With a little more outlet angle, the Bertha would surely conjure up a completely different curve - maybe Sven would like to work the cylinder again with his fingers.

Here are the key data:

Cylinder: Parmakit SP09

Crankshaft: BGM 51/105

Carburetor: Keihin PWK 33

Suction system: Polini membranes on 2 flaps with Straw speed connector

Ignition: Vespatronic

Exhaust: Big bertha
