While cleaning the bike ('91 EX-500) last night I noticed three hoses hanging down. The bottom ends are not connected to anything. All three disappear up underneath the gas tank and I'll have to take off the tank and the front fairings to see where the go. Hoses are dry (nothing dripping out). Any ideas before I start pulling fairings off? Are these some run-off hoses for fluids? Something to maintain pressure in tanks/reservoirs?

BTW, bike runs fine and I asked a mechanic to look it over in general about 2 weeks ago when he did some other work on the bike. He didn't mention the hoses.

I would say they are likely the drain hoses for the airbox. My old 6E had two drain hoses plus a fuel overflow drain hose as well.

I have a Ninja 500 (essentially a newer EX-500) and I just did the tune-up on so I know exactly where those hoses connect...and yes, they're nothing to worry about.

One is an vent hose for the battery, and the other is some kind of air intake (to equalize pressure?) that goes into the carbs.

They're both supposed to be unplugged, so everything's fine...

Winko ~ Your mom obviously doesn't know me very well (that statement could be so wrong). /images/icons/laugh.gif

Thanks, guys. I thought they were okay but I figured I'd check.

On my 90 ex there are two gas tank vent hoses and the battery overflow hose.These are probably what you are seeing.

I'm pretty sure one of them goes to the high speed grizell pivot...spuirt a little oil in it and turn the bike upside down to allow it to lube the bearings. ;)
