I have a superjet with a 701 that I put together. The motor was ported and the head was shaved and it has a pro tec pipe. When I first took it out it ran good for about 15 minutes and then it would not get full power. I tried lowering my pop off that did nothing. I switched carbs with my friends running ski and it did the same thing. I changed the coil and CDI and it didnt change anything. Then I pulled the flywheel and saw that the stator wires were rubbing the flywheel and 4 of them were almost worn completly through. So I changed the stator and it still did the same thing. So I took the intake off and checked the reeds and they look fine. It seems to run ok from idle to 1/4 throttle then it just bogs. It runs great out of the water and if I pull the back end up while riding the rpms will shoot up and if I keep hopping I can get it up to speed.
