paxx Posted November 16, 2019 Share Posted November 16, 2019 1 hour ago, Jord said: What is that silver thing for? It's a vac diaphragm on euro spec bikes. Controls a solenoid valve and has something to do with sound dampening.

ElGonzales Posted November 17, 2019 Share Posted November 17, 2019 That silver thing opens a flap in the air box for additional intake air, controlled by the negative air pressure the motor produces around 4500 rpm. 1 Link to comment Share on other sites More sharing options...

Mad Posted November 18, 2019 Share Posted November 18, 2019 In Europe we have stricter lows , so Yamaha made this valve that limits the amount of air coming in to the air box . at 4500 rpm that valve opens , letting more air in , this limits the sounds below 4500 but don’t affect the performance because gives air when needed 1 Link to comment Share on other sites More sharing options...
