BGM PRO exhaust liner set to seal the exhaust at the cylinder neck.
Each cylinder type (Malossi, Polini, Quattrini, Pinasco) unfortunately has its own diameter at the exhaust port, which differs slightly from the original. p> p> p> p> b> b> b> b> round engine running b> b> bbr /> Likewise these bushings can help to cure unexplainable vibrations and a not round engine running. If the exhaust port has so much clearance that it can move (under load and exhaust pressure) on the cylinder flange, this will lead to the phenomena mentioned above.
With the bushings the exhaust can be tightened properly on the flange. This usually eliminates the cause of the vibrations. The engine can now be tuned properly or runs as it should, because no more air from outside gets into the exhaust.
In the supporting working area of the exhaust (resonance area) fresh gas from the cylinder, which has entered the exhaust, is pressed back into the cylinder. However, if this is enriched with fresh air due to a leaking exhaust flange, the mixture for the engine can become lean. Therefore, these bushings should be ready to hand at every exhaust mounting.
Simply insert into the exhaust flange and push the exhaust onto the connecting piece, tighten. Ready.
Set with 2 sockets ( 0,10mm and 0,15mm wall thickness)
