701 driving me crazy

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.

If it runs ok out of the water, check that the waterbox baffles have not come loose. Take it out and shake it and see if you can hear them rattle.

do you think that the wires rubbing through on the flywheel shorted something out and messed up the CDI and then when I switched CDI's it messed that one up too.

when my stator went bad due to water corrosion, my ski did the same thing, would run fine for a few minutes, then only hit maybe 4000 rpm. after letting it sit for an hour or two, same thing would happen.

you might have a bad stator.
