Earl put together an awesome thread for balancing your Gen 1 carbs. http://www.venturerider.org/forum/showthread.php?t=56723&referrerid=11995 With Earl's permission, I took the thread and converted it to a PDF. I also put the pictures with the appropriate text. This gives you a document that you can easily print out and follow step by step. I was able to balance my carbs in less than 30 minutes and now that I have done it once, I'm sure that I could do it in under 20 minutes. Thanks Earl! Ray -
OK all you super mechanics. I found a 1996 RSTD for $2500 on craigslist. It looks real nice in the pictures and only has 24,000 miles. Here's the bad news. He says it needs 4th and 5th gear replaced and the carbs tuned. The carbs are not a problem for me. Is there any known issues that would cause 4th and 5th not to work (linkage?, shift fork?), and how hard is it (whats involved) to do the repair myself. Would I have to remove the engine or can I do the repair on the bike? The bike has a lot of safety chrome I could swap over to my bike and maybe sell this one for a little profit if I can do the work. Let me know what you think.

Hello, everybody. I've been lurking here for a few days now. Ever since my girlfriend informed me that we need a different bike than our Roadstar if we are gonna go very far. Seems the Roadie's ride is just a tad tough on her tush. Also, we want hard bags, fairing, overdrive, cruise, etc. etc. You all know where this is heading. I have been looking for a few days now, and I have found a 2004 RSV that has been covered inside a garage since 2007. Seems the guy bought it, then promptly lost interest. Fast forward to now. We plan to buy it. I know about what has happened in these years. The battery is probably dead as a doornail, the oil needs changed, the tires may be flat, may even need replaced... My big fear is the gas. I know the tank needs drained, as do the carbs... Think I'll get away with that? Or will the carbs need to be removed and gone through? I know that when I decide to fire up one of my old cars, I need to mess with the carb, but there's only 1, and it's right on top. I'm not intimidated by the prospect, just rather not disturb them if I don't need to. In reading your fine forum here this morning, I found that the float levels are probably too high, and need adjustment anyway, but for now I'd like to just get to know the bike before tearing into it. Thanks for any advice you can give me. Bert

I have been using Bg 44K in my dirtbike, fourwheeler, trucks and cars and after using it and dissassembling the carbs they are spotless inside. Not only does it clean the carbs but it also keeps the valves clean and keeps the piston rings clean. This product is great and I highly recommend it o everyone. It is the true "tuneup in a can". If you are having issues with poor fuel quality and carbs gumming up or varnishing try this stuff

I bought this 84 venture and was looking at the carbs and noticed one of the slider springs is completely gone. where can i get one and how much are they? -
Well, I finally got around to checking my valve clearances on Biggal this past weekend. I'd been putting it off all summer and this week I had some vacation time so I used it to catch up on some long overdue preventive maintenance. Many thanks go out to all the discussions on this website and MD 's at Don's the last 2 years, as well as Freebird's posting about getting the carbs off in the Tech section. V7Goose's article article in the Tech section was my main instruction book for doing the valves. I also used your procedure for setting the floats on the carbs. Thanks Goose. Dingy has a very good spreadsheet in the Tech section as well and it came in very handy. Thanks Gary. You made working with metrics a lot easier and keeping up with what's shims are in each location. After changing the coolant, as well as the oil, filter, sparkplugs, tightening the steering head bearings, and syncing the carbs (didn't really need that) she runs like a champ again. I'd say I've got my 12 dollars worth of help and more!! Thanks to everyone again!

My brother has a 1997 Royal Star. He got a DUI last year and the bike has been sitting since then. This week he got his license back so we started trying to get the bike running. The battery was toast so we replaced that. Next problem was that when we tried to start it fuel was shooting out the carb drain hoses. After a little research we discovered that the floats were probably stuck and the fuel pump was constantly running and overflowing the carbs. I tried tapping on the carbs to unstick the floats. That got the fuel pump to stop sending fuel spewing out the drain hoses and the bike would even start but it wouldn't run. It would idle very rough and I suspect only on one cylinder. I figured that the carbs were probably too gummed up for the thing to run so we pulled those off and cleaned them. I didn't completely break the carbs down. I took enough of the brackets off that I could remove the float bowls. I removed the float bowls and all the jets and cleaned everything up with spray type carb cleaner. The two carbs on the left were pretty filthy, I imagine because the bike was on the kick stand leaning to that side. Once the carbs were cleaned up and reassembled we put them back on and the bike won't start at all. Anybody got any ideas?

I'm kinda bummed. The biggest thing is that my gas tank started a slight rust last year when I did my 83/86 Frankenbike. I've been dealing with it all season. The rust dust in the fuel will accumulate in my carb bowls until there's enough to foul my carbs and they start running like crap. I'm sick of blowing & draining my carbs regularly. After I clean them out, my Venture runs like a raped ape! I did put a couple of filters in line just before the carbs, and that lasted quite a while. Ultimately I'm sure I'll need to pull the gas tank (UUuugh!!) and clean it out/coat it. I bought a fuel filter that will filter down to 10 microns and I'll probably be installing that today so I can ride for another month or two despite the cold temps. I did some research on the web, and I think the rust dust varies between 5 and 200 microns. We'll see how that goes. My Vboost is totally awesome! The weather is all gray. It's supposed to snow this weekend. Down at the local Honda Powerhouse, there is a '98 Valkerie with 50K miles for 5 grand. I wish I had the money...I've always loved the Valkeries... Doug

Curious, tks! -
I'm about to put my new-2-me 2000 RSV away for the winter and wanted to know if there was anything in particular you guys do when winterizing your scooters? I plan on taking the battery into the house, and running the carbs dry, draining the bowls, Is there anything else I should be watching for? Do I need to remove the gas tank to get at the carb drain plugs? Oh yes, I put a good wallop of Fuel conditioner into the tank and ran it for a good 10 minutes so the fuel hit the carbs. Cheers, D.W.

Is it still possible to buy carb. rebuild kits for my '83 VR. If so, where can I order them and what info do I need off the carbs. Thanks in advance for your help.

Is there anyone around Louisville,Ky who knows how to syn carbs,and has a carbs syn kit?

What is the 'recommended' position of the E clip on the carb diaphragm needle valves? Needle valve is similar to one on bottom of attached picture, not exactly but close. I am getting these carbs closer on Speedy, but I stil have a slight popping below 3,000 RPM's & gas mileage is somewhat lower than expected. About 25-30mpg range. Carbs are 35mm mikunis with stock VMax jets in. 150 mains, 90 PAJ2, 170 PAJ1 & 37.5 pilot. Gary -
after changing the plugs, changing the oil, i decided to install skydocs shim kit before i synced the carbs using the carbtune pro i got from zane. thanks again zane. 3 carbs, no problem. last carb, DOH! i must have put the nylon nut ever so slightly wrong, and SNAP! broke a diaphragm housing. lack of patience i suppose. only had about a good 2 hours of clear weather before the rain came this weekend. i found some new ones on ebay. so i bought 2, 1 for a backup. and i got 2 needle kits, just for spares.

Had my 25K miles, 85 venture for about 6 years, it never ran right - it would cut out at 6200 rpm, spit, sputter at full throttle on excelleration, I know it needed to have the carbs cleaned but I didn't want to spend the money. I just forked out over 200 bucks to clean the carbs, new plugs, wires, now it hesitates and doesn't go over 5200 rpms at full throttle. If I don't have it wide open I can reach redline in 1st. 2nd gear tops out at about 4500 rpm. Mechanic claims it is not the carbs mainly because it goes great until 5200 rpms ? I'm frustrated - I don't know how to fix the bike myself yet - IF it was a carb problem at 6200, so why not a carb problem at 5200 ?? I've already paid the bill, don't want to invest more money. I feel like I should have just left it alone if this is as good as it gets. Any ideas ? -
I'm new to the Ventureriders forums, but want to say thanks to all that have posted. I purchased a 2006 RSTD Midnight about a month ago with 12,000 miles on it. I bought it from a local Harley dealership, so don't know how it was maintained. All was fine until I went to work two weeks ago. The bike ran like it was running on 2 cylinders and had no power. A guy at work shamed me into paying the $12.00 to become a full member. Best money I have ever spent. Been busy at work so haven't had time to work on it until the night before last. Some post I have read said it sounded like a stuck float or a plugged jet. I tried to tap the carbs after shutting off the gas...etc. Well I thought it was time to pull the carbs and clean them. Thinking 12,000 miles on a 5 year old bike wasn't all that much and the bike may have sat for some time. I decided to grab some spark plugs, oil and filter, and a CarbTuneII ($50.00 on Ebay), brakes, and an Avon Venom rear tire. Started tearing the bike apart. pulled the seat, then the tank. When I went to pull the Airbox, I noticed the two boots that connect the airbox to the carbs were loose and had some oil on the carbs. I pulled the airbox and cleaned the oil from the boots and the carbs, replace the spark plugs, synced the carbs, change the oil, changed the brakes, and replaced the rear tire. The bike is running fantastic now. I want to get out for a ride but the rainy Ohio weather is keeping me in. Everything I did to the bike in the last two days I learned here on this forum. I have to say it would have cost me well over $12.00 to have the steelership work on it.... Just wanted to say thanks.

Ok So i am jumpning feet in . The low end stumble when trying to take off , the hard starts in the summer while having to use full choke. And the long wait to warm up even in the summer is driving me nuits. The 96 rstc came with kromewerks aftermarket pipes and I doubt it was ever rejetted. I was planning on taking the carbs off and turning the pilot jets richer 1/2 to a full turn but was told by a friend if the carbs are gonna be off just step up the main jets one size larger. does anyone have any info on this . Is it a good idea and if so where do i get the jets and how do i know what size are in there now? I have a dose of seafoam now to see if this is the problem. i plan on doingthis labor day weekend so I want to get ready now.

Got the bike last week. Running ok, horrible gas mileage. Just didn't feel right. Previous owner supposedly had the carbs rebuilt. Found that one of the carbs idle air screw was closed. Set all to 2 1/2 turns and gained substantial power, but sluggish at wot. Starts great idles fine, but something still seems off. Changed plugs and wires, no change. Where I was at yesterday; gas mileage is horrendous, wot is fluttering, #3 cylinder exhaust temp 450ish and the rest 150-190ish. Starts easy, idles easy and runs down the road fine. Feels like I can drive it anywhere. This morning I decided to pull the carbs. Boy it was a pita, throttle cables at the carb were a nightmare and reinstalling the cables and the vacuum line from engine to the air box was a royal pain. Well, looks like I got half a rebuild. Looks like new diaphragms (or nice old ones), new air jets etc... The wet side was pretty nasty, but got it all cleaned out. Put it back together and started it and it now idles at 3500+ without the choke. I can hold the throttle closed and will drop to 1500, let go back up. When I put my hand slamming the throttle it barely moves. Out side cable has slack, not sure about the inner cable. Before I put the carbs on I tried to get all butterflies near closed and the same as best as my old eyes could so whatever sync that was on it is long gone. Ideas on what I can do? I don't have a sync tool, but have a single vacuum gauge. I thinkmit might be an issue with the inner throttle cable. I tried single gauge sync yesterday before I decided to pull the carbs and I had real bad flutter in the gauge so I limited flow and saw only about 1mm of vacuum in all carbs. Hopefully that changes tomorrow. I'm real tight on money right now, so I won't have a sync tool for another couple of weeks.

I guess I’ll begin by introducing myself. I’m Lee Winders and live in the small town of Mansfield, Tn. A few months ago I purchased an ’83 VR. The motorcycle had been setting up for quite some time. The man I bought it from hadn’t ridden it very much. He bought it from someone that I think had let it set up as well. The man I bought it from said the last time he rode it, it quit and he was unable to get it to run again. He said it acted like it was not getting gas. He had shown me the bike about a year ago and I told him if he ever wanted to get rid of it to let me know. He called me a few months ago and asked if I would give $200.00 for it. Well I figured it would be worth it if only for parts. I got it home and the first thing I did was remove the carbs. They were a mess to say the least. I went through and cleaned them as well as I could. I removed the gas tank and drained it. I replaced the fuel lines and filter on the tank side of the fuel pump. I still have the original fuel line on the pressure side. By the way, the bike has 19,000 miles on it. I put fresh gas in it and tried to start it. After about 10 minutes of messing with it, it finally hit. It will only run when fully choked. And then it runs very rough. I’m sure the carbs are way out of adjustment. I also notice the when trying to crank it, one of the carbs didn’t have any suction at all. Possibly a stuck valve. I don’t have the air box on it at this time and I’m sure this would also affect the way it runs. There is a lot of other work that needs to be done on the bike but first I want to know that the engine is ok. I really don’t think there is anything seriously wrong with the bike. It’s going to be a work in progress. I welcome all the help I can get

I have the 86 and it is doing ok. It has sat in the garage for the last 5 weeks while I recover from another hernia surgery. Ok throttle is a little stiff. Also have to really crank hard for wide open throttle. Cables appear to be in stock location. There is a differance if the bars are turned left or right. I have not checked anything much yet really. I did notice when I put the carbs back on the attempting WOT the bracket at the carbs actually deflects and moves some. There is nothing stuck or stiff in the carb assembly. worked great by hand when rebuilding and reinstalling them. Am planning on lubeing the cables up with my cable ease stuff. Wondering what all fairng pieces I have to remove to get to the cruise control cable box and if people have issues with the routing of the cables especially in the triple tree area. Thanks everybody.

Hi, long time no see! To make a long story short: My Venture acts weird, the problem right now as I've pulled the airbox is that I can see butterfly #2 not closing eventhough the idlescrew does not touch it!? If I slack the cable at the trottle the throttle will not pull back by itself. If I force the throttle back, the butterfly closes...If I adjust the cables so that I have "normal" throttle operation I still have slack but no go on #2 butterfly!? Is there a spring or something among the carbs that is either missing or come loose since I rebuilded the carbs 5 years ago (yeah, I'm afraid it's been sitting still since, only occasionally startups...) ? regards from Sweden Abbe

I picked up a long reach phillips screwdriver. Already synch'd two carbs. Anyone else wants to stop by, the cost is free, and I can give you a quick tour of the great river road from Guttenberg to Dubuque, IA. Takes about 5 minutes to synch the carbs and 1 hour to ride on some of the best MC roads in flyover country.
-
If I crack the throttle wide open quickly while at highway speed, I smell gas, the smell goes away as I resume normal speeds , all carbs appear dry externally, thoughts oh wise ones? -
While performing some routine maintenance on my bike, I removed both sides of the (what I call airbox) under the tank, that connects the hose from the airfilters into the carbs and found that they were wet with oil inside them. The foam gaskets that mount the two sides together were pretty wet with oil as well. Is this an issue or normal occurence? At first I was thinking it was fuel since they open to the carbs, but it was definitely oil. Where is that coming from? They were not dripping wet and there was more on the left side than right, but it was enough to get my attention. Thanks Mongo

When cleaning my 02 I noticed a lot of small cracks in the rubber elbow from the carbs to the engine. I don't think any go through the rubber....yet. Is this common and is it likely to give me grief anytime soon?
