So I know it is somewhat of a common problem on our 1st Gens. They are just so dang fast the gas fumes in the tank cannot keep up with the bikes. My bike has developed the “gas smell in the garage” syndrome. It seems to be getting worse. I have checked the diaphragms, checked for overflow from the carbs. Adjusted the idle screws. Trying to decide the next step. So, what are the solutions that you guys have found ? What is the next couple of steps I should try ?

i recently rebuilt the carbs in the bike and now they overflow for no reason. if i put the bike up on the centerstand and shut of the fuel the bike become more responsive untill it begins to starve, i turn on the fuel and the leak stops for however long i feel like letting it run. i get on drop it off the kick stand and begin driving it begins pouring it out the overflow as fast as the pump can trow it. ive taken them appart again and hooked each carb to the fuel line manually and turned on the bike while pressing up on the float. the fuel flow stops as soon as the float presses on the valve. so the valves appear to be working. ive taken all the floats out and submerged them in fuel and will check on them in a few hours to see it they are sinking but they dont apear to be. any ideas on why this leak is being so intermittent and limited to the right bank only but all 4 carbs are running super rich. -
i went a few weeks ago to help a young member with his 96 royal star 28mm carbs. got it to run better, but while checking out the float levels the drains screws wouldn't stop leaking. i was going to help him out after i got back from ohio, but he took it to a shop where the guy who owns and does the work. he worked on it and got it running good but when josh took it home it started leaking gas out the overflow again. he took it back and they worked on it again and said the carbs are right, but the gas is boiling in the carbs at about 100 dregees and causing the carbs to overflow. i was wondering if anybody else had heard of this before. i have worked on about 30 of these bikes and never ran into this at all. terry is the guy working on it and i invited him to come on and post on here and see if anybody can help him out. terry's two wheels is the name of his shop and i have sent several friends there that has bmw's as he is really good on them. he also works on several other brands of bikes including a couple of police harlies, hondas and bmws. i'll keep an eye out on this and let him know what to look for when he comes on the site.

So here's the story relating to my 88. When I first got it I needed 1/2 choke just to keep it running. MARCARL and I cleaned out every oriface possible with the carbs still on the bike with carb cleaner and compressed air. We set it up best he could and since then I have seafoamed it with a very strong mixture overnight a few times, and add several ounces every 3-4 tanks. Once in a while I put in a heavier dose . It's had at least 8-10 cans thru it. I had a case of a sticky float (I think)on the #3 carb earlier this year as gas was pouring out the overflow tube. But it "fixed" itself when I tapped on the carb body with the handle of a screwdriver (I was on the side of the road at the time). Again...dosed with seafoam and it seemed to be OK for quite a while. Now I'm smelling gas (no overflow) and the idle usually but not always wants to hang up around 2500 rpm. What messes me up is that occasionally it is just fine! (900-1000) I"m finding I don't need any choke to start it. I bought a 2nd carb rack (minus diaphragms and sliders) and I have diaphragms and the basic VMAX ebay carb kit. Just wondering if anyone has any suggestions. Even changing out the carb rack would be a major undertaking for my wrenching comfort level so I'd like to wait for off season to do that.

Good afternoon everyone. Went for a little ride today and noticed my kickstand had a bit of oil on it when I stopped. For whatever reason, when I first seen it I didn't think much of it. (Not sure why it didn't register right away.) Anyway, when I came back to the bike there was a couple of drips under the overflow hoses pictured here. It seems the leak was coming from the second hose from the left. I checked my oil and it seemed to be OK. I had the same issue happen last summer - only one time. It was fine after that. This is the first time this year it's happened. There's been no oil change done recently, however it's just about due. The only time it happened last year it was about 1000 miles into the most recent oil change. Then nothing for a long time. Now again. I guess I don't understand what's causing it. Also, can anyone tell me what each of those hoses is the overflow for. I'm assuming gas, oil, antifreeze, and ???. I'm not sure which is which - other than that second one, based on the oil coming from it. Any assistance would be great.

I think you would get some attention riding this bike down the road.

Ok all, I need your help. I'm looking for every possible failure mode that would cause fuel to leak out of the overflow on the carbs. After rebuild install, carbs were leaking out of number 1. Then taking it off and checking everything out we put it back together. Number 1 no longer leaked but no. 3 & 4 did. Very frustrating. It appeared to happen after some problems with the throttle cable, where we removed the carbs again and turned them upside down to keep the cable attached to the carbs. Not sure that putting them upside caused it but the timing is there. Background; 1987 Royale, 8900 miles. Carbs were rebuilt by a trusted V-max guy. The bike has been synced and runs great except for the gas leak. The tank has been lined (Red) new fuel filter, new air filter, new spark plugs. The carbs didn't originally leak when first installed. So looking for input on all possible causes of the leak. Also, would carbs leak more or less during regular idle? Thanks in advance, Bill

OK, this could be something that I did but I'll put as much information in here as possible. I have a coolant leak, usually after riding the bike and it gets hot, looks like it is coming from the right side (looking forward of the radiator). I'm having some trouble tracking the leak down. The radiator itself always stays completly full. In fact if the bike is cold and I remove the cap fluid will come out. The temp when riding always stays right in the middle of the green after it warms up. The overflow tank is empty, and I just filled it to the proper level a few weeks ago after I changed the radiator fluid. There was a slow leak from the drain plug but I replaced the gasket under that and it isn't coming from there. The puddle is a little forward and left of where that puddle was! Both ends of the overflow tank hose are connected (assuming it connects right under the cap of the radiator), so it isn't disconnected. Here are the items I think may be an issue, I was wondering if I could get some help on where to start looking. - Overflow tank hose has a crack. - Overflow tank itself has a crack. - When I changed the coolant I wasn't exactly sure if the knob you turn (I believe they called it a drain diverter or something) got put back in the correct spot. I couldn't find the writing they talked about. Not sure if this would cause a leak. Thanks for any help you can give. Let me know if you need some pictures I can go snap some. I'm trying to get everything buttoned up as best I can before our first trip on the bike this weekend.

Replacing the coolant, filled to the top of radiator, ran it, let it cool, filled to top again, ran it, still needs more. How do you know when you do not need anymore? When the coolant gets hot, I assume it bubbles to the overflow tank under the seat, but how does the coolant in the overflow tank get back to the radiator? there is only 1 tube to the overflow tank.

Can a defective radiator cap cause coolant to bubble (for my lack of a better description) back into the overflow bottle? I believe coolant returning to the overflow is normal, I've just never heard it doing so. This only occurs when the motor is really hot. I've had several lst Editions and I've never had one do this even when touring in and through Death Valley (Furnace Creek) in 110+ weather. My temp guage was only a little past half way when I stopped today (108 here in Dallas) and killed the engine and within a few seconds this gurglling/bubbling sounds starts and today I even had some coolant run out the overflow line and puddle underneath the rear of the motor. Weird. I picked up a new radiator cap and hope this solves this issue. The radiator is clean, no clogged cooling fins, good thermostat, water pump in good condition and Engine Ice as coolant. Any advise would be highly appreciated. -
I been having problems with what I think is sticky floats. Tried the seafoam, didn't work. tried running the heck out of it - didn't work. Replaced the set in carb #3 - that one stopped burbing fuel thru the overflow. NOW the others are burbing fuel. I can't believe all four would/could go bad, but I am open for suggestions. Thanks, Bob

Was tracing out the overflow tube (Fuel Breather Tube) on my 06RSV from the gas tank to see which of the tubes under the bike corresponded to that tube. Anyways, I noticed under the seat the tube has what appears to be an inline filter before exiting out the bottom & venting to the ground. Is there really a filter inline? If so, why on an overflow tube? Just wondering...thanks!

I was in the process of overhauling the carbs on my 86... I had thown in a heavy dose of SeaFoam and shortly thereafter it started really acting up... but mainly #1 cylinder was really not wanting to fire. I had drained the bowls and took a week or so to get back to them and then broke them apart and opened up #1... and when the fuel bowl cover came of... look what I found in the bottom... http://bergall.org/temp/venture/carb-rust.jpg Yep, that BROWN stuff is rust. Everybody put down your hands... it wasn't the tank. It was from the fuel overflow pipe. Just above the bevel at the top of the picture, the inside of the overflow was coated in rust. #2, #3 and #4 look fine, dull but clean. That tiny idle jet (37.5) looked opaque on all four... rather a light brown, but almost clear... when I tried to blow through them, it didn't work. Seems part of the problem was easy to solve. I also found the enricher diaphragm on #1 had RUST. Now it's the right rear so I thought it would more protected from the elements but that's what I found... It may be a rare case of "Mike gets the good one"... but it's an easy check for you guys that get that filter housing off to pull the overflow lines and look inside! And of course, mine had four totally different lengths of overflow hose... come on... put your hands down... the front carbs take ONE length and the back carbs take ONE length... I have four separates... and one (by golly) seemed to be the right length... the others were varying degrees of too short. And yeah, #1 was the shortest. My day for weird I guess. Nromally I would just soak the jets and bodies in cleaner and then use carb cleaner to blow them out. This time I called around and found a "speed shop" that would ultrasonic clean them and the jets for $20. And believe me... it's a world of difference. What looked like a human hair opening in the tiny jet now looks like you can fit three and everything is CLEAN. Strangely the bath didn't get rid of some of the aluminum oxide where the rack bolts go but everything else was sparkling. The regular motorcycle shops wanted $80-$150 for the bath and blowout... shop around.
