Im having troubles with my 01 GP1200r it tops out in the low to mid 40's and max's out at 5500 rpms. I had a blown cylinder due to a oil line coming off, so I replaced it and added an oil block off and d-plate. I know my speed is according to the dream-o-meter but it was hitting 68. Regardless, I have no bottom end, reaching only 5500 rpms, once it planes out it has no power either. Seems to cavitate more when hitting waves. Ive also replaced the fuel filter and spark plugs. The power valves turn when I start the motor but not sure if I needed to tune the cylinder I replaced. It revs to max rpms out of water, it only bogs when it in. It has been in the shop since the cylinder blew last summer, not sure what could have changed......
