    2001 Gp12R Help

    Hey guys, i have a GPR with a Pro-tech head, power pipe, ride plate, intake grate, arrestors and other minor mods. The ski just rolled 120 hrs and i purchased it last year with 90. I have had great raliability after swicthing to premix and adding waveeater clips and couplers. But, since i bought it, it always had a dead spot where it bogged down at 1/4 to 1/2 throttle while getting on plane/accelerating. I never thought twice about it because by feathering the throttle, she pulled right through.

    Now yesterday, it was doing this a little bit worse and started to bog on top end after it would hop out of the water. It was weird because it was very intermintent. Then, before i put it on the trailer is was bogging and spitting and sputtering at anything more then 1/2 throttle.

    My inital idea is that the carbs need a rebuild because i am confident that they are all original. Any other ideas???
