I bought a 2001 rxx last year from a guy in hamilton ontario, Canada. it worked great for a week then i had to rebuild the engine new pistons rings and gaskets. My rxx has only worked once this summer every time i take it out it seems to be starving for fuel or a plug breaking down. it just doesnt have the snap out ouf the water and the top end sticks at 6000 rpm maybe 55 mph top speed. i have tried everything with this machine new plugs high test fuel and i have tried ajusting the fuel on the psi gauge. the guy i bought it from said to run it at 3 psi. if you have any suggestions of what might be going on here please email me back. thanks andrew
