1983 venture. When warm, falls of face with any throttle. -
When removing the fuel tank from the MC I disconnected the fuel hose from the fuel valve and the brass tube that the hose connects to came out of the fuel valve and remained in the fuel hose. Can I just reinsert the brass tube in the fuel valve, or will that cause the valve to leak gas?

I ran into another local rider today at Cabela's in Sidney NE. Chatted about the upcoming riding season. He mentioned that last fall he intended to take a ride on his 97 RSTD. However he discovered that his petcock gasket failed, leaked the entire fuel tank contents into the carbs and flooded the cylinders and crankcase. Is this a common problem? Good reason to turn off the petcock when stored? He indicated he was going to have the local dealer look at it. Thoughts, ideas.....

Hey all. It's been a while. Been riding too much to spend time in front of the computer! I think I have a problem. Went out to go for a ride this afternoon, and out of the blue, she wouldn't fire. ('07 RSV) Always fires on the first crank. I pulled the choke out all the way, and if I cranked it a while, she'd finally catch and idle real slow. If I touched the throttle or choke, she stalled. Then I started replaying my actions in my mind, and realized I never heard the fuel pump clicking. Off with the seat and side panel. Tapped on the pump with my fingertip, and when I turned on the ignition, the pump ran like the carbs were clear empty. Now it seems fine. Starts and runs like new. Is my pump trying to tell me something? Do they give warning before they fail? This was a New Old Stock bike, that might still be under warranty. Will the dealer replace the pump because I said it was having a fit? Looks like my Christmas road trip is out the window. Thanks for any help and opinions. Bert

This will be kind of a long one, so read the first paragraph then you will see if you want to skip the first section on fuel pump rebuilding. The other two sections are not very long. If you want to read about gravity feed (fuel pump bypass) go to my next post in this thread. If you want to read about the Cheap Ebay Fuel Pump, go to my third post in this thread. Last week my RSV was leaking lots of fuel while I had it running to warm up for a ride so I had to abandon my ride and figure out what needed fixing. It turned out to be the fuel pump; it was leaking lots of fuel from the seam where the two halves come together. Apparently this is not a common failure and I could not find a diagram of the fuel pump exploded into component parts. It is only listed as a complete assembly, although you can replace the points if needed. New pumps cost approx. $200 for OEM so I began researching what my alternatives would be: Repair, replacement, or bypass Since I could not find a diagram of what’s in the pump, I decided to see if I could have a look for myself. Hopefully I would see something that can be tightened, patched, or replaced! Nothing to lose right? I removed the pump from the bike and took off the metal mounting clamp that secures the pump onto the bike. I wiped the pump clean and concluded that what holds it together are the little tabs that are bent over the middle seam. In this pic I have already pried them open to separate the two halves. (Now I wonder if the first thing I should have tried was to just hammer all the tabs down tighter!) The next pic shows the two halves apart, and a large washer and very thin gasket that were inside. The half on the left has a rubber diaphragm that is ‘pinned’ to the unit at its center, so the metal washer and gasket had to be pulled up from under the diaphragm by flexing the diaphragm through the hole in the washer. I hope I explained that well enough, because I don’t have a good picture of that. Anyway, the washer and gasket went where the red arrow points, with the flimsy little gasket going between the metal washer and the metal pump body. After looking things over, I decided it seemed that the most likely cause of the leak was the little gasket. Did I mention it was really thin, floppy, and flimsy? I tried to put it back together but couldn’t get the washer and gasket over the diaphragm again without distorting or wrinkling the gasket. It looked like it needed to be seated perfectly and in such a tight space, I wasn’t sure I had done it. (To shorten this part of the story up….it didn’t work. Gas still came out of the seam so I took it apart again, still pretty sure the gasket was the problem.) Next, I went to the local Napa and asked if they had thin, gas-proof gasket material, and showed the guy my pump. He went in back (they are an auto repair shop also) and came up with a partial sheet of 1/32 gasket material that he said should work, and gave it to me for free. I traced the washer on the gasket sheet and then cut it out with a razor. I reassembled the pump and hammered the tabs back down. I gently blew into the ‘inlet’ stem and it made kind of a honking noise, which I took as a good sign because no air was coming out of the seams as far as I could tell. I installed it and turned on the key. It made the usual clicks for a moment, then stopped once pressurized, and did not appear to be leaking. I started it and let it run for a few minutes and then turned it off. I felt around the pump and my fingers did not get gas on them. I let it sit for a while longer then felt it again and there was a very small drop on my finger from the underside of the pump. I pulled it out again and looked it over. I wiped it off and blew in it but still no obvious air leak and a good ‘honk’. Then looked at all the metal tabs and realized some of them could be tapped down a little tighter and more evenly. Doing this did seem to tighten things up and may have been good enough, but I decided to do one more thing. I have some metal HVAC tape so I wrapped the pump body with it twice around. I put the mounting clamp around the middle of the pump, which helps tighten the tape like a hose clamp would and put a hose clamp on the other side. See pic I went for a 30 mile test ride, stopping frequently to feel for gas on the pump, and so far it is working. I’ll leave that side cover off next time I ride so I can keep checking until I am satisfied it will hold.

Has anyone ever seen the entire fuel gauge flash on and off, like two flashes- pause, then flash again? My bike died the other day while riding home about a mile from work with the gauge flashing. It was like someone turned the key off. No sputtering or anything, just died, with all the electrical components still on. I pulled over, turned the key off, back on, fired it up and came on home without any incident. Any thoughts? Thanks, Creole

I have an aux fuel cell connected via a valved T between the Main/Reserve selector and the fuel pump. Can I use that at Maintenance Days to run my bike if I take the tank off? Do I need to short the fuel sender unit or something? Dave

Hello All, Quick question and background. Son rides a valkyrie. We just went thru all 6 carbs and reinstalled... REAL pita to reinstall airbox runners onto top of carbs. We reinstalled and cranked up and have a low idle issues that we believe to be an air leak, further investigation tomorrow. Now for the question, one of his forum buddies we visited had a fuel "bag/cell" hanging from the ceiling with a hose and pinch clamp to run bike without the tank on... Great idea huh. Have any of you made one and if so, out of what with what??? Wanting to make one tomorrow that I will use also on RSV when finished. (torn apart now) Give me ideas... hose, check, clamp, check, bottle.... woops. I need a fuel resistant IV bag! Ideas anyone?:think: thanks for the help, James:biker:

Here's an interesting Fox News report on the new E15 blend of fuel. It appeared a month ago, but now that we're into the new year it's even more prevalent. http://video.foxbusiness.com/v/2000862202001/

A friend of mine heard that some one on here replaced his fuel pump with one from a car. IF this is true, does anyone know what car it came from? and how it worked out.

I have an 86 that I just bought and it will not start. It has to be a fuel issue, it will start with starting fluid or a little gas poured in the carbs. The fuel pump is working and gas is getting to the carbs (line from pump removed key turned on). It has started once and ran for about a minute, really smooth, and quit. Is there something that would cause the fuel pump to stop or just dirty carbs? BTW did swap in a known good pump and same story.

My '02 RSV seems to have developed a slight fuel leak. The leak is a slight drip coming from the end of an allen bolt. You can see the drop in the attached pic. What is the assembly that the bolt holds? Anybody have any idea of how to fix this? That assembly looks like a pain to remove! Any help is much appreciated.

I'm having a hard time finding where I have some fuel seeping from after using the choke to start on cold mornings. I do have significant cracks in the rubber intake manifolds that I suspect my be letting the fuel weep through, and the leak is up high. Any thoughts? -
What grade do you use ? Cb

So I thought I had it licked but back to the drawing board I guess. My 85 is kinda new to me. I bought it awhile ago but until the summer I just sat and waited for my attention. PO needed money and it was to good a deal. I have done alot of work thus far, from draining the gas tank to replacing the fuel lines and filter and ran a can of sea foam thru. After the filter was changed it seemed to run better but today I went for a good 200km ride and its not fixed. I have not opened the carbs yet. I was hoping to avoid that, seafoam has worked on other bikes I have owned in the past.....I believe the bike sat for 2 years ish before I got it. On the road it pulls ok up to 4000rpm then dies....like its running on pilot jets. Check the plugs and they are black? To much fuel? New air filter. The bike starts and idles perfect. Just won't pull on the road, I mean these bike were known to pull.....hell its a vmax motor....ideas as to why it would run aok up to 4000rpm and then die's out....hard to stay at 100kms/hr in 5th?? My Buell would go 100 in 1st/2nd!! HELP! Any, even bad imput is ok with me:) Does someone in Ontario excell at carbs? My budget is kinda tight and it seems to be a big job if the carbs need to come out according to my searches on the site. Thanks a bunch!!

Is anyone familliar with any of the CRC fuel conditioner products? I came across this product http://crcindustries.com/auto/?s=06141 and this one http://crcindustries.com/auto/?s=05068 at the local Canadian tire store. With all the talk about ethanol spiked fuels lately, I went on the CRC site and found the following bullitin. http://www.crcindustries.com/files/Ethanol%20Fuel%20Stabilizers%20PR.pdf Has anyone used these products? How would you compare them with seafoam? Here is a link to a comparison of three of their own products as well http://crcindustries.com/auto/marine-products I also attached a PDF data sheet.

Motorcycles make more sense that autos and trucks. My wife's main vehicle has always been a big Jaguar XJ8 (I'll admit that I love it too!). But now that we are moving to a small mountain town in New Mexico, I just do not trust ever finding a qualified Jaguar mechanic there. I do just about all my own work on the Jag, just like the bikes, but there are some complicated things on that vehicle that I have no experience with, so I would really want a shop I could trust. We agreed to sell the Jag here in the Fort Worth area and buy a sensible Japanese compact all-wheel-drive for the mountains. So far, so good, but that is where it started getting weird for me. The Jaguar XJ8 is a big 4-door luxury sedan with a 300HP V8 engine - it has enough power that it is sometimes hard to drive it in a sedate way! And this big car gets 32 MPG on the highway! I have absolutely no problems making the entire 600 mile trip from here to Ruidoso on one 19 gallon tank, even when driving a steady 80 miles an hour most of the way. Now the Honda CR-V I just bought today is only rated for highway mileage of 26 MPG, and most of us have learned to never expect to even reach the posted EPA numbers. So what the heck is wrong with the world when a big luxury car with a great V8 engine gets so much better fuel economy than a standard Japanese vehicle with a small to mid size 4 cylinder? That little CR-V seems like a great little vehicle, but I'm betting I'll curse the mediocre fuel economy for years to come. Goose Anybody wanna buy a big beautiful Jag with GREAT fuel mileage?

Just watched Motoring 2012 on TSN and they were talking about Ethanol fuel in carburated engines. Ethanol causes deterioration of rubber carb parts. Any ideas as to which gas stations sell regular gas with no ethanol in Canada?? Learned something new today!!

Went out tonight to start my bike, pulled the choke, turned the ingnition on....no fuel pump clicking. Pushed the starter switch anyway, fired right up but low idle rpm's with choke on....not good. Tried to give a little throttle....died . Recycled the ignition no clicking, no starting. Put the cover back on her and got in the Tahoe and went to work a very unhappy soul. I think a new fuel pump is coming. I think it has been intermittent for a few weeks now though. Never died or left me stranded but I would notice the pump not clicking after being parked for a day or more. I think when I tried starting the bike maybe the pump made connection then and I could'nt here it over the starter/engine turning over and she would ignite. I still have warranty till November, but I don't know if I should take it in. My luck, is when I get it there, it will work just fine and I will be out my bike for a week. Are you guy's having good luck with your after market $45.00 pumps? If so, I will just go buy one of those and be done with it. Thanks, Carl

Hi All, New Member here and learning a lot. I have 2002 Midnight Venture with less than 8000 miles. She still has the original tires. Below is a picture. Lately she has been been doing nothing much beyond sitting in the garage collecting cobwebs. At one point several months ago I brought a new battery and went to start it up. It did not start and there was fuel leaking from the carb overflows. I am in SW Florida and and we have 10% ethanol in our gas and I'm figuring that did me in. Thanks to the great article from Freebird: http://www.venturerider.org/forum/showthread.php?t=7830 I got the carbs off and cleaned up. Now the bike runs great and idles great. I had them on and off about 8 times before I finally got it right. On the last attempt I looked through one of the pilot jets and realized the tiny pinhole was a bit smaller than the rest. No amount of blowing would clear it. I have a carb cleaning tool that has wires in various diameters. I poked the smallest one through a good pilot jet and felt no resistance. I then poked it through the one with the smaller pinhole and felt resistance. I pushed it through and then blew it out again. I could *see* some crud fly out of it. After that it finally idled OK. Only issue is that I somehow ended up with a left over screw that I *think* is from the bike. Probably from the area around the middle of the bike because I also replaced the fuel filter and checked out the fuel pump which turned out to be OK. There is a picture of the screw. It is a philips head and about 3/4 inch long with a washer. If anybody recognizes it and knows where it goes, I would appreciate it if you could let me know. Since I got so much from this forum already, I would like to contribute something. One of the warnings in dealing with these carbs is to not lose the tiny O-Ring in the edge of the bodies that gets exposed when you remove the diaphragms. Of course I lost one - perhaps it was never there. At any rate, I had a set of O-rings I picked up a while ago from Harbor Freight to fix a leaky hand held sprayer. The smallest in this set worked pretty well in the carb and I like I said, the bike is running real sweet now. There are some pics showing the O-ring set and the label. Your biggest problem will be what to do with the other 381 o-rings in the set. I also found that using plastic cups to protect the intake while the carbs were off worked pretty well. Thanks again Freebird for the great article. I probably would not even have tried this without it as a guide. After about the 4th time taking them on and off, I was able to do it in about 10 minutes. First time is always hardest!

Has anyone ever mounted a Mr. Gasket 42S fuel pump on a 1st Gen. If so, where and how did you mount it. My stock fuel pump has gone out and I already have a 42S that I used when I was trying to get my '83 running. I would like to use it if possible but I haven't found a good place to mount it. It's a little too big to fit in the location of the stock pump.

Today was a beautifull day in the Cascade mountains of WA state, and my sweetie and I rode our '88VR from home here in the Tacoma WA area, over Chinook Pass (Hwy 410) and down the eastern slopes stopping at Whistlin Jacks Lodge for a huge fish and chips lunch, then on a little farther on to see the newly realigned highway replacing the one that was buried in Americas biggest landslide on record, then turning around and came back home the same route. 264 miles round trip and achieved 49.63 mpg by keeping to the posted speed limits, and running mostly on cruise control. Amazing..... for me that is. I think my bike is running well........ and I just might squeeze a 245 mile range out of a tankfull of 89 grade fuel. Just sayin...... -Pete, in Tacoma WA USA '83,88 Venture -
How much fuel is left in the tank when the last bar on the gauge goes away?? The knob for the reserve valve on mine was broken off when I bought her so I don't know if it's set to reserve or not.

So many of you guys have a lot more mechanical wisdom than I do so I am posting this question for your opinions..... I recently went completely through my bike getting it restored (99RSV), new paint, new parts, new mods, blah blah, blah- you get the point. When we reinstalled the gas tank getting everything put back together the low fuel indicator light now stays on. The contacts appear to be good and I cleaned them for good measure(where they connect in front of the tank), still the light stays on. This morning I replaced the fuel thingy in the tank.....still same problem. Now though here's what happens: Turn key on, get correct fuel level reading on gauge momentarily then all fuel bars blink 7 times pause, blink 8 times pause, blink 8 times again, then only the top fuel bar continues to blink(the bar for totally full) none of the other bars light, meanwhile the low fuel indicator remains lit. The tank has about 5 gallons of gas in it. One more thing I will include is that I replaced all my indicator lights in the dash with LEDs which take much less wattage to operate are a lot brighter and have a long long life. What are your thoughts ?? :detective: -
08 RSV - bought new in 2008. For the first two years, I got > 44 MPG...one-up or two-up...didnt much matter. Bought a Bushtec trailer, and rode up to TN (2-up)...got a steady 38 MPG uphill, downhill...headwind, tailwind. For the next two years, I've gotten 38 MPH, 1-up, 2-up, with trailer, without trailer. Two weeks ago, the fuel pump finally gave up the ghost. Yamaha dealer replaced the pump under warranty. For the last 400 miles, I've averaged 45 MPG...1-up or 2-up. For the life of me...I cant explain what bearing a fuel pump would have on my gas mileage!!! :confused24: Any reasonable explanation(s) would be appreciated...
