The additional SC-Project AFM (Air Fuel Modifier) units are projected for the specific use in combination with the completed, semicompleted exhaust systems or with the only silcencers produced by SC-Project to obtain the best performance with the substitution of the exhaust system,adjusting the carburation.
Assembling a better performing exhaust system a carburation leaning is created: riders have to slightly improve the gas contribution and air in the engine to level the potentiality of the exhaust system to the gas requested by the engine.
In the last generation motorbikes when the original exhaust system is replaced by a more performing SC-Project model a better and quickier exhaust expulsion is obtained: it is appropriate to adeguate also Co, that is the value of carburation . air-gasoline. Riders can reach this through the installation of an AFM unit which balances the gasoline input in the engine with the outgoing exhaust, which is best thanks to the new exhaust system (in the only silencer version too).
