    Cylinder Water Leak? GP1200R

    I have a 2000 GP1200R. I am getting a small amount of water in the center cylinder. At idle, it runs on two cylinders but once I get going, the third one kicks in and runs fine, all day long. I assume the bit of water was preventing spark but once the rpms are up, it fires.

    I need to fix this am wondering what to check for first. Was thinking I'd take the head off first to check the gasket. I checked the head bolt torques and they are fine. Any other places to check prior to digging in deeper? thanks

    Yeah check head gasket. If it looks good apply some grease to it. Could also be the cylinder base gasket, did you replace a cylinder recently? Make sure spark plug is torqued correctly. Carb manifold gasket too could be loose.

    I wouldn't run it until you pressure test the engine to find the leak.
