GL 1100 Emissions Hoses

Postby bobfell » Wed Feb 29, 2012 6:36 pm



I have a 1980 GL 1100 and i took the tank out to clean the rust out. After putting it back, i found two (substantial looking) hoses that i could not find an end to. One begins inside of this
and ends with a connector that looks like this
. The other hose runs to a vent underneath the gas tank. Any help would be seriously appreciated. Thanks.

The crankcase has a vent hose that allows crankcase blow-by (combustion fumes that blow past the piston rings and into the crankcase) to be taken out of the crankcase and put back into the air filter area, so that they can be sucked back through the throttles and burned again. This is the lower hose in the diagram below. However, the blow-by fumes, as a by-product of combustion, contains water. As these fumes cool off entering the air cleaner, some of that water can condense out. This water drains through the upper hose in the picture into the storage tank (which should be emptied periodically!).

Hopefully this helps you out a bit.

You Wont be able to tell by sight when it's time to drain the emissions storage tank. But you WILL know you gone past that time when you find what looks like water contaminated oil (yellow looking gunk) in the bottom of the air box interior. Remove it. Do a good cleaning of it.... i got tired of not being able to tell when the tank needed draining.! now days, i don't worry about that.

The 1500 is worse. It doesn't have a tank, it just has the hoses with plugs in the end. You have to unplug the hose and let the gunk drain out. If the hose fills up - your air box gets wet.

i'd be finding a way to let it vent to the ground... a length of hose below the frame... and when riding this will create some vaccuum. as air travels across the end of the hose. It's an "Old School" trick to ventilate engine crankcases... i had a 6 cyl. ford truck engine with venting problems, no matter what was done with the EGR valve. and i could see by the dipstick that i had a problem... i just went out and bought a length of heater hose about 3 ft long.. placed one end on the nipple to the crankcase breather cap and routed the open end of that hose to sit about a foot and a half above ground... i zip tied it into place... went about my driving routine. and never saw water vapor in the crankcase ever again. Just plugged off the EGR valve and hoses left it sit in the engine valve cover. No more watery yellow gunk on the oil dipstick.!

What length of time would be good to check and drain this tank?

Thats a hard nut to crack wally. As it depends on how much riding you do. if you ride a lot, then once a month would be a reasonable length of time to remove the tank and empty it.. The tank for my '83 1100 has been consigned to a box of parts i no longer use. It will still drain, but not into a tank you have to remove to keep the air box free and clear of Gunk and making a mess of that... Honda could have done much better when designing this emissions catch tank. Like a sight glass.! and a bottom drain valve... i suppose one could add a drain petcock to this tank.. That would eliminate having to remove it to drain it... Idea ! :)

The problem with that is you'd then have a bypass for your air filter - and instead of draining out fluids, it would be sucking up dust, dirt and anything else you find down near the road, and feeding it, unfiltered, directly into your carbs/engine. Not very good for engine longevity.
