PSR Block Off Plates
Complete fitment list at bottom of this page.
Includes everything seen in the photo above.
Eliminates the Air Re-circulation system on the RSV4 and Tuono V4 for better EGA readings especially during sweep style dyno tuning.
Kit requires use of High Temp RTV silicone to seal the plate to the cylinder head.
The RSV4 and Tuono V4 are fitted with a secondary air system. This system allows fresh intake air to be injected into the exhaust system to lower emissions.
The secondary air system's purpose is to dilute the exhaust gas mixture so that there are less pollutants. This helps the RSV4 to pass national emissions testing.
This Secondary Air Block Off Plate Kit allows you to bypass this system.
*Please note: Owners of ABS models will need to remove the engine in order to install the rear block off plate due to lack of clearance with the ABS module/pump
Installation Notes Below (please note this was performed with the out of production AF1 Blk Plt kit, but the process is the same):
When installing this block off kit you will be working with three air hoses. These hoses can be unhooked and left on the motor or traced back to the controller solenoid and removed. (The controller solenoid can not be removed - it is located in the center of the "V").
Step 1: Secondary air plate shown. (Repeat procedure for rear cylinder bank). Please note: the three bolts that hold the cover on can be stripped easily; take care when removing.
Step 2: Secondary Air hose removed.
Step 3: Install AF1 Racing block off plate. Tighten the 3 M5 bolts to 5nm (3.7 ft.lbs). High Strength thread locker (RED) can be used, but is not required.
Step 4: Gain access to Secondary Air delivery line.
Step 5: Remove secondary air delivery line.
Step 6: Fit the cap supplied in the AF1 Racing kit. Re-use the secondary air delivery line clamp to secure the cap.
