Kawasaki 1100 ZXi running at 2/3 full speed
Last summer I somehow blew a hole in my exhaust manifold. I'm a relative newbie to PWCs yet somehow managed to diagnose the problem and replaced the manifold myself. However, when I put the ski back on the water for its test drive it only got up to 40 mph as opposed to its previous top speed of 60 mph (as read on my dash gauge - I realize these are probably not true speeds but that's irrelevant to my problem). Can anyone tell me what may be causing this problem? I found it interesting that I'm reaching 2/3 of its former speed and its a 3-cylinder motor, and thought that perhaps something is wrong with one of the cylinders, but it seems to run "normal" in every other respect. Maybe its something completely unrelated to the exhaust manifold repair.. Help!
