Valve cover hose

[mike10]

I just noticed I didn't put the hose on from the top of the valve cover to the air box. Can someone tell me what size that hose is, diameter ? Whats it for? .....GS1000 1980

I dont know the exact diameter but i just used a piece of vacuum line from the auot parts store. Measure the hole in the airbox nipple and get that size ID hose. As for the function. That tube acts as exactly like a PCV valve in your car.. relieves crankcase pressure and it even supplies some engine heat to the airbox. In theory it will help recycle unused combustion gasses and the engine heated air will suppress any "frosting" of the carbs in cold weather. Be sure the wire mesh is under the housing on the cam cover too.. that keeps oil from being sucked up into the tube.

Hi, diameter is 12mm or 1/2''.Its an antipollution thing.
Its like a pcv on an old car or truck.

Yes? I'm here (finally).

If I was home, I would simply go out to the garage and look at the label on the hose that I bought.

Since I am about 1000 miles away from home, I will, instead, go to the Alpha Sports site and note that the description says "HOSE, BREATHER (11X15X250)".

I guess that means that it's 11mm inside diameter, 15mm outside diameter and 250mm long.
Alpha's price for that hose is about $30, everyone else's is about $20, but it's better than it seems.
You actually get about 6 FEET of hose, which is much more than the 10 INCHES you need.

If you go to the auto parts store, you might find some 7/16" hose, but it's going to be much thicker-walled and hard to use.

Yes, the auto parts store hose is thicker but I bought some anyway for my bike. No F'ing way I'm paying $20+ for a piece of stink'in hose from Suzuki.

I have some of that suzuki oem valve cover hose floating around if anyone is interested. The OEM hose is thin walled and when new is quite flexible. Any hose you find that fits at local auto parts store will have a fairly thick wall which will become rock hard over time especially in colder climates

Well, obviously I splurged and got the "real stuff". As I mentioned, it's much longer than you need, there is actually enough in there for 6 or 7 bikes, bringing the effective cost down to about $3 per bike.

At the same time I "splurged", I kinda went overboard. I also got the proper vent hoses for the carbs, the proper vacuum hose for the petcock and the proper fuel hose. I'm tired of fighting auto parts hoses, the extra money is worth it to me. All of them except the carb vent hose have much more than you need for a single bike.

Silicone heater hose at the autoparts stay flexible, even here up north.

Some times, you just gotta spend the money.

So does the original hose.

I'll all for the OE fuel line and vacuum hose, just didn't feel like paying $25 for a length of hose.

So which one of you guys with "extra" valve cleaner hose wants send me a hunk?

You in a hurry?

I might be home in about three weeks or so.

I'll be happy to send you some when I get there.
