SHIPMENTS ARRIVE SPORADICALLY WITHOUT NOTICE. NOTE: The Factory Pipe kits for the Yamaha FX1 (FIN701FX01) have been discontinued. As the only available option, the FX1 customer can modify the Factory Pipe Mod Chamber kit for the Super Jet to fit your Fx1. Please email us for further details if this is your preferred option. This has been the preferred choice of most of our FX1 customers as the Mod chambers are almost identical to the FX1 castings except for some minor clearance fit. The installer must make a relief clearance in the chamber so the chamber will not hit the front motor mount and possibly starter. The Factory Pipe exhaust manifolds are the same between the all 701 motors so an alternative exhaust manifold is not required.
