Im the NEW to me proud owner of a 1983 Venture Royale.. Wow do I have issues

[Droneh8tr]

I've got alot of work ahead of me to get ready for a last week in august trip to Canada.. I'll elaborate on that and the overall condition of the bike I bought, but for now could I get an answer to these question:

 

on top of the carburetors are 4 bent tubes, tubing is suppose to be attached exiting the area to the back... where do these 4 tubes go or are they just vented to the atmosphere?

 

On the twinkie is a large tube, does this tube go to the bottom of the air box? Mine is venting to the side of the bike..

 

Sorry to be all business for now, but i've got several things going on and these immediate questions popped up..

 

Thanks...

You should take pics of the problems and we can jump in and help you.

The 4 bent tubes on the carbs are overflow valves in case a float/needle valve sticks open, it allows fuel to exit bowls, there should be a rubber tube on each one routed back near front of rear wheel where the fuel dumps to ground. See attached pictures. 2nd picture is with fuel tank removed.

 

The twinkie tube should go to the left side of the air box and also center via a tee connection. This allows the vacuum in carbs to suck the vapor out of block and reburn it through piston chambers. Tube on left side of air box is to allow excess oil that may accumulate in air box to drain back into block while bike is on side stand.

Four tubes come one from each carb and are vented behind the engine, there is actually a wire bracket to put them through. They are overflow tubes.

The hose coming from the twinkie goes to the bottom of the air box, a real pig to hook up. Some bikes also have a T in the hose to route it to some other place.

The 4 tubes are indeed vents. Originally came with rubber hoses routing to the rear and downward along the frame. Also serve as overflow tubes for when the inlet valve sticks open. The large tube on the 'twinke' is crankcase vent, usually routed up to the air cleaner housing, but that results in condensed oil buildup and dripping down on the engine. Some of us have rerouted the vent tube down opening to the underside of the frame....with condensate dripping on the ground.

Make sure you get those vent lines routed correctly and the proper length, that's how my fire started.

I'll definitely use that technique in the future..

Thanks for the pics.. I did not see another tube, very interesting... I'll look in the morning.

Im sssoooo gonna look for that bracket, thanks..

Interesting solution, I'll consider that as well

Ouch on the fire... Yeah I'll pay particular attention to the length and routing.. thanks for the heads up..

Hey eveyone.. I just didn't think it important, so I didn't say anything. But, when I saw several pics of what I should have regarding the overflow lines routing, I thought I better bring this everyones attention...

 

The two rear cylinders carb overflow tubes coming out the top are facing forward... the 2 front carbs have their overflow tubes facing backward (like the pictures).. Did the PO twist the overflow tubes of the rear carbs to face forward for some reason? Should I route 2 overflow flows to the rear, and two to the front, or am I expected to twist the rear carbs tubes rearward...

On California intended Ventures, the carb vent is routed into a carbon canister. The overflow/vents are joined together with a preformed 'T' hose for each pair of carbs and joined again with another 'T' then a single hose goes to a solenoid valve next to the TCI. While your bike may not be intended for sale in California, a previous owner may have installed carbs from a California bike.

Those vent elbows are swaged/pressed into the carb float chamber and you run a real risk of breaking something if you try to turn the elbows to face rearward. Don't ask how I know this.

The pic is of my 1991 California market Venture. I removed all the emissions plumbing and routed the overflow tubes to the rear. I utilized 3/8" tubing and incorporated a 'U' turn in the hose coming from the rear carbs (the vent elbow points forward on the rear carbs).

I considered leaving the 'T' fittings and hoses and run a single tube rearward, but that tube would have interfered with the crankcase vent tube to the air cleaner, already a bear to re-install without adding even more congestion to a confined space.

First pic is of my 1991 California carb set-up. Second pic is of a non-California 1983 carb setup. Third pic is of a California 1983.

Thanks Prairiehammer!that was a great explanation... And with pics... I can see using T fittings to fix my issue, BUT, in the 91 California pic, I noticed the hose exits to the front of the carbs. I'll have to see how that could route on my 93. I'm sure it will, I'll just have to figure it out.. Also, I like the idea of only one vent line being routed overboard and not 4..

2 issues down..

Looking at Prairiehammer's 1st picture, It seems possible that you could swap the rear float bowl cover's on the right & left carbs, this would then have all 4 tubes facing rearward. I believe that the float bowl covers are interchangeable.

 

It would require carb rack to be removed from bike to do this.

I like that to.. I'll be removing the carbs eventually so I'll look into that AND using T fittings. Thanks

That might be possible, one might have remove all of them to do it right. As you might notice the tubes are not perfectly perpendicular to the cover, there is a reason for this, and I believe it is too clear the fuel line when the carbs are installed.
