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.

PHBG carburettors 17,5mm replica

• Model as Dellorto PHBG, very good replica
• Hand choke
• Connection diameter of the manifold 24mm
• Connection diameter of the air filter 32mm
• Nozzles/jets suitable for this carburettor are Dellorto 5mm jets/nozzles
• Carburettors are delivered with a blanc nozzle/jet
• Carburettors should always be cleaned before installation

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!
• Chances are that the carburettor and the filter will not fit directly between the cylinder and the frame. By filing the little holes in the manifold, it can be modified in such a way that the carburettor and filter will fit, even with frame brackets attached.
