    87 Yamaha FZ700 help

    Any advice would be very appreciated. Bike cranks and runs well but occasionally have a little steam and a few drips of water come out of a small hole in the cylinder head. No coolant in the oil or vice versa. Is it due for a head gasket ? I've owned several bikes but this is my first liquid cooled one. Thanks in advance fellow gearheads.

    Is it the weep hole for the spark plug well by any chance? If so that's just condensation that collected in that recess boiling off.

    Thanks for the quick reply! Not sure honestly. There are 2 of these holes. One on each side. This is my first liquid cooled bike. It's a inline 4 cylinder and my plugs are in the front. These holes are between cylinder head and block.
    Thanks again.

    Pictures would help. Also, see if it tastes like coolant. Welcome to NESR! How long have you had the bike?

    Dammit Josh, you're probably already circling his house with a pressure tester, HC sniffer, and new head gasket.

    Does the coolant level ever drop? If you aren't riding it enough to know, fix that problem first

    I thought it was understood around here that if you post a tech question I'm allowed to sneak into your garage and start poking at things immediately?

    Yeah, but he's new. He knows not that of which he speaks. Come fix my carboned up KIPS, I have no bottom end.
