Differences from the original BADASS Diablo cylinder:
- On the GPO cylinder, the web of the split exhaust port is slightly ground down to minimize the risk of an exhaust-side heat seizure.
- On the GPO tuning cylinder, the edges of the overflow channels near the cylinder neck have been chamfered to facilitate piston ring installation.
- The original BADASS cylinder is shipped with a GOL piston, while the GPO Divertimento is equipped with a GPO piston matched to the cylinder. Differences are evident, among other things, in the crown profile and in the cutouts on the piston skirt for the overflow channels.
- On the GPO Divertimento, more space has been created for the nuts used to secure the cylinder base.
- The required M6x62 mm stud bolts for mounting the cylinder base, as well as nuts, washers, and stud bolts for the intake, are included as standard with the GPO.
- The intake tract has been repositioned so that the carburetor and air filter are now aligned horizontally and no longer point diagonally upward.
- On the BADASS Diablo, the embossed “30 km” logo is positioned off-center, whereas on the GPO Divertimento it is centered, as on the original Swiss cylinder.
The cylinder base is factory-designed for Swiss 50/2 (502) engines. However, the mounting holes for the German 50/2 engine casing are marked. This allows you to drill them out if necessary and use the cylinder as usual for your moped with a German engine casing.
The large intake allows for the use of the 17 mm swiing® tuning carburetor, provided it is mounted with a short air filter cap, a matching clamp (short), and the appropriate cover plate (long/deep). Please note the installation direction during assembly. The piston is installed with the arrow pointing toward the exhaust on the exhaust side. You can find the larger 43 mm version of the racing kit, the matching 17 mm carburetor, and the air filter parts described above in the accessories section. A good, affordable standard replacement part. GPO – GOOD PARTS ONLY.
