BK Twisters Factory Pipe headpipe repair kit.
This kit is designed to replace the water adjustment set screws supplied with Factory Pipe exhaust systems utilizing their tunable headpipe.
This kit will fit these exhaust systems: Yamaha 650 701 Super Jet B pipes for Super Jets and Blasters.
Also fits Factory B pipes on Kawasaki 800 SX-R, 750 SX, 650 SX, and X2.
These are much easier to tune with the T-handle configuration.
