    Need help from 2 stroke gurus 1999 gp1200

    what would the symptoms of a blown cylinder base gasket be between cylinders on a 99 gp1200? compression is 140 on all 3 and carbs were just rebuilt and just swapped out the entire ignition system and still shes runs like she is in limp mode and she only gets upto 35mph and 5500 rpm, guy on the water with me today told me his gp1200 did the same thing and after he changed and rebuilt everything it turned out to be a blown base gasket between cylinders. does this sounds posible?
