THROTTLE BODY NMAX SEMI DOWNDRAFT BRT

 

THROTTLE BODY NMAX SEMI DOWNDRAFT BRT

for Yamaha Nmax 155 motorbike, ready size 32mm, 34mm. To order, put the size you want in the purchase notes and ask for stock first

Suitable for standard exhausts, bore and bore up engines

Recommendation to use the BRT ECU to set the fuel flow

Due to the use of a TB with a large Venturi, the incoming air will increase... so it must be balanced with more petrol flow too
