Tip: we always advise to check and clean the cylinder before installation and to finish the ports in the cylinder with a 1000 grit sandpaper. This way the edges are no longer too sharp because of the Nicasil coating, this will considerably extend the life of the cylinder / piston.

Note: 

• Do not overtighten your carburetor to your manifold, as this may cause the clamp to break. No warranty when you have overtightening the clamp!
• The float chamber is mounted with 4 bolts, 3 long and 1 short. Always ensure that you always place the short bolt on the corner of the air adjustment screw! If you screw in a long bolt here, it will hit the air adjustment screw and block it!
