So glad you mentioned to drain the oil and change filter after carbs flooding. Probably a gallon of fuel mixed in the oil. That was a surprise!! Thank You, much appreciated.
Just finished my Carb overhaul after a couple of months on the road working, this video was a lifesaver putting em back together, thank you Brother. I should have sent them down to you but it was a good challenge that I couldn't resist. Whosoever thought up diluting gas (Petrol to me (UK born) with ethanol ought to be strung up, lol. Only Full Fat goes in this Baby from here on in. God Bless Texas.
Well done! I just got a Royal Star project bike that has been sitting for several years. After watching your video I am inspired to give the carb rebuild a go!
This is great information. I have a 2009 Venture that had the carbs jetted. The bike runs a bit rich so I'm looking forward to getting the mixture right. Thx for sharing this!!
with warm and lowest possible idle, turn each air/fuel mixture screw in and out to get premium idle, low speed mixture. about 1.5 or 2 turns out when running best means pilot jets are correct size. More than 3 or 3.5 turns out means pilots need to be a size richer. Closed or very little open means pilots are too rich, go to size leaner(smaller number)
Thanks for video GM! I am the original owner of 97 RS. I last cleaned the carbs over a dozen years ago and am pretty good about using a fuel stabilizer when storing the bike. Despite that, I have had gas leaking from the carbs, so I decided it is probably past time to yank the carbs, clean the jets, and replace the gaskets. The parts were pretty clean with only minor build up, but the gaskets and rings were almost solid. Even though I have cleaned the carbs previously, your video has been very helpful.
@@geezermoto7820 Just watched another of your vids and you suggested replacing the rubber intake manifold boots. I have never replaced mine, so guess I'll order a set off ebay and replace those while I have the carbs off.
@@kennethcasper106 yes, the boots "manifolds" get hard, then suck air Put a heavy layer of threebond 1184 on before bolting them up. I've had new ones leak when not using 1184. Threebond 1184 is available on ebay or through your tucker or parts unlimited dealer
@@geezermoto7820 I received the new intake manifolds. On one, the vacuum fitting was not glued in. Do you know what would be a good adhesive for this? Will the 1184 hold it? THx. Ken
how do you check and adjust the throttle position sensor? im also having a problem with popping when i level off the gas when i get up to speed. thank you for your videos they have been very helpful
The TPS normally needs no adjustment unless it's removed but it's done with a multimeter and specs from the service manual. Popping on deceleration is from the slow circuit being too lean. Try a size larger pilot jet (sometimes called slow or idle jet)
Have you noticed much performance gains from switching to pod filters, jets and a gutted exhaust? Wondering if I want to go the whole 9 and rejet or just clean my idle jets and leave the bike stock
Free flowing exhaust and a good aftermarket filter will make a nice improvement, but not a big improvement. I don't care for pod filters, but a better replacement element is good or performance air box/air filter combo
Hey man love this video I just pulled my carburetor out this will be my first time working on one but I do have some mechanical knowledge on cars my question is why would there be oil splashes into the air box any idea ? Thank you in advance and I’m rebuilding the exact carb
The Crankcase vent system goes into airbox, if too much oil is installed, it will end up in airbox or an engine with failing rings or valve seals will do it. No alarm unless you are fighting a good bit of oil
I recently purchased a Yamaha 1997 1300 cc tour deluxe with 6600 miles. I bought the bike pretty cheap but running very poorly. I was told the gas was left in the tank & carbs for many years. I ordered the all balls kit and a ultrasonic cleaner thinking that I can rebuild my carbs after watching your video. I took my time and I started out dissembling carb 3 and than ran into some issues. I can not remove the needle jet screw that is behind the plug (the plug was not present on my carb) , also the float valve brass fitting hold down screw is also frozen and damage from excessive force on trying to remove them. Both screws are damaged and may require drilling them out . I have used my best snap-on screw driver on them unfortunately the brass flat head screw is no longer a flat heat. Is it possible to drill the needle vale adjustment screw without damaging the carbs or is that a no go .
well, the simple answer is sometimes you can, sometimes you cannot. The stuck fuel/air adj screw is a bigger prob. What i do alllll the time is when i cannot get them out, i buy used carb body or bodies on ebay, and using the different parts, etc, i build up a perfect set of bad ass carbs you can ship to me if you wish either way i wish you luck and feel free to bug me all you need to lol I'm in West Tx btw
Hey, just a quick question maybe you could help with. Is it an absolute must having to change the carb bowl gaskets after opening them up or can you get by with the same gasket if it's not torn? I'm trying to decide to separate them clean the jets or just seafoam and put them back on the bike for now until the replacement gaskets arrive in a couple weeks. Thanks in advance for the advice.
sometimes you can, sometimes you can't. but you must get in there and clean them up. get threebond 1184 or yamabond 4 to seal bowls if leak with old gaskets (o-rings)
Ive torn 1 carb apart and reseated everything. But the diaphram is not pushing the black cylinder and rod back into the middle when i push it. Is there a lube im supposed to put on that black cylinder? What have I missed?
Hey there GM, I chatted with you a few years back about my '07 RSV where I had a heavy fuel smell in the garage after rides. You recommended the seals on the needle might be going. I didn't get a chance to work on it then, as life got in the way. I have added monster ovals since then, picked up a carb repair and a jet kit for that and then had to move from the Midwest to your neck of the woods. Rode about half the year here then got a constant leak soon as the bike fires up. So now I have the bodies off the bike. I am in the process of tearing down the carbs. I wanted to know, how far I need to go? Does the vat damage electronic components? Do I need to remove the throttle body position sensor?
Wanted to provide an update: I bought new plugs, a fuel pump and filter, as I figure it was time to get that out of the way while I was wrenching. Broke down the carbs and soaked everything I wasn't replacing. Dipped in water then Naphtha just as you did. Installed the jets from the kit and replaced all the seals, needles and seats. Fired right up and purred like an angry kitten. I was over the moon that I was able to do it just attending your 101 course. Then after a day and a half, she wouldn't start. I kept fiddling with the pilot screws, the idle speed screw, and nothing brought her back. Well, after about a couple weeks of fooling with it a little after work, ordering several pilot jet sizes, I kept getting the feeling she was starving for fuel. I finally did a petcock and fuel pump flow test. Petcock was fine. Pulled the fuel line to the carbs and tried starting her and the line was sputtering, so I rigged up a temp shop fuel tank so I can get a look at the carbs while trying to start it. the temp tank had some clear line on it and I noticed the fuel was not getting sucked down into the system. Put the original pump back on (which I salvaged out of the trash because I had a feeling I might be needing it after reading a bunch of blogs and watching other carburetor videos). Lo and Behold! She was back to purring again! Just wanted to thank you for such a detailed video on carbs and specifically the same ones I was working on. Couldn't have done it without you and now I am a bit wiser on how to troubleshoot these. In all my years wrenching on cars and bikes with my dad, and I'm now 51, it was my first time tearing down and rebuilding carbs. He's still up north and I wish he could have been with me. But I'll get to show him when I take a ride up there. Can't thank you enough, sir.
Hello, I have a 97 Royal Star 1300 with 32k miles and the previous owner definitely used ethanol fuel, I have run Seafoam in the tank a few times and I only run non ethanol in my carbureted engines, It seems I have one carb that doesn’t want to idle and I have picked up the same rebuild kit you have in this video, I’ve pulled and rebuilt motorcycle carbs but nothing with 4 carbs and TBH I think I’d rather pull my carb assembly and send them to you with the kit, How do I reach you outside of RU-vid?
Since I can't get through on email for some reason. I have went through the carbs on a 97 royalstar with all new needle valves and seats and everything. The bike runs absolutely great but no matter what I do, I'm getting gas out both of the air vent tubes on top of the carbs. I actually set the floats so I should be starving for fuel when into the throttle pretty good but nothing changes
I do not. Just compare all 4 floats and confirm all 4 little seat "tabs" are same position. This is how i do it. ...you can probably find a "float height" measurement, then hold upside down to where float weight is keeping them closed, and measure from float bowl gasket face to far edge of float, this is your height. ., Find a video on any bike's float height to see how it is done, you can measure height with drain hose as well, but this method would be hard to explain here. Just dig a bit, it's all out there and feel free to bug me more! Lol. Also, I'll make a vid soon
Hey I’ve rebuilt mine and I cannot get them to stop leaking out of the overflow. I’ve adjusted the floats, and I’ve done everything I possibly could find. I’m lost, and ready to set the bike on fire.
yes, I do jobs shipped to me often. Normally it is 100 on parts and 400 on labor, I'll put phone number in next message and remove after you get it to keep the auto bots off of me
you can buy manifolds on Ebay very reasonably, those are always used up with cracking after about 10 years of use. Seal them against head with threebond 1184 or yamabond 4. They will suck air etc. Could be a reason for smelling fuel at warm up. or leaving choke on too long. You only want to choke as little as possible, on choke can foul plugs quickly.
Hello, how do I contact you? I have a 2003 Royal Star Venture that needs the carbs rebuilt (sat for over a year). Got the All Balls rebuild kit but just haven't had time to rebuild them.
I have a 1996 yamaha royal star 1300 .irebuild the carbs an now I have one carb over flow .what can I do .can I send you the carb .what's you charge to build them
Hi, thank you for your videos. It's hard to find much information on these old bikes. My question is about which kit to order from eBay. My bike is a 1983XVZ 12 T. When you look at the kits on eBay all of the XVZ bikes are 1300s and not 1200s. I do see the VMX 1200 for 1983 models but I think that's the VMax and I'm not sure that would work. Could you please share some of your knowledge and tell me which rebuild kit to order for my 1983 XVZ 12T? Thank you for your videos and have a great day. Mark Nance
Search this on ebay.... Motorcycle Carburetor Repair Kit Main Jet Sub for Yamaha VMAX V-Max 1200 VMX12 It is vmax 12 but the needles and seats and bowl gaskets should be what you need Soak your old brass in a gallon of carb cleaner and reuse. Meaning, reuse your old jets and needles
Geezer Moto Thank you for your quick reply, that is a ton of help. I couldn't figure out why they don't list an 1983 XVZ 12 and started thinking maybe I had the only one in the world. My virtual only has about 17,000 miles on it but my business keeps me away from riding very much, it almost looks new. I also have a 1979 Honda Cbx with 11,000 miles on it and did have the carbs re-done about two years ago and I'm sure to keep non-ethanol fuel in it and at least start it often. I'm a Texan myself and live most of my life and Tyler. I am in Utah now for 26 years but I am in the process of getting back to the best state in the union, around Tyler Texas on Lake Palestine. Thank you so much for your help and I would send you my carbs but I don't have time to take them off and will be taking them to a local mechanic that is trustworthy. Again, thank you so much for that bit of knowledge I would not have known what to do. Good luck and have a great day. Mark Nance
Geezer Moto mr. geezer, sorry I don't know your first name. Please excuse my messages I'm doing voice recognition and have a very thick east Texas accent. I did sell my 1969 Mach one because I didn't want to have to totally Resto mod that car. That was hard to get rid of but I don't think I could ever get rid of the Cbx. It has the six in the one exhaust which looks really cool and all the decals look brand new on it. The mechanic that's going to work on the venture carburetors had mentioned before I talked to you. if I could get the entire kit get everything for the carburetors. I'm thinking that from what you said maybe all of those parts in the VMX 12 kit will not work in my 1983 Venture 12. Is that correct? It sounds like you were saying that only the needles, seats and bowl gasket or usable from the VMX kit on the XVZ 12. Thank you for all of your help and where in Texas are you? Have a great day.
@@marknance7070 your engine is tuned differently thank a vmx so the slow jet main jet and needles will all be different, but, the brass (your jets) are good, just soak in carb cleaner for like 2 days or so and get them clean as new. ...usually all you really need is the bowl gaskets and float and needle seats where the fuel comes into the carb. Triple check your rubber diaphragms, cannot have holes and must install to where they work.....watch video on this. And replace your intake manifolds if hard or cracked
Hi Tim, well I really couldn't tell what part of Texas but I knew it was down there. I was actually born in La Mesa Texas between Lowbook and big Springs out west. We still have a 600 Acre cotton farm in La Mesa. I mostly grew up in Dallas and Tyler Texas. I'm getting ready to move back to Tyler and trying to get the venture to start so I don't have to push it into the moving truck and drop it on me. Those kids that I was looking at look like they were $39 for a bunch of stuff in them so I'm not really sure what to order. Are there kits that have some of those other things that you mentioned in your last comment that I should buy? I'm sorry to be such a pain but there are so many kids available I'm not really sure what to get. Thank you for all your help and is there something I should do on RU-vid to help you like thumbs up or something? I want to accommodate you for your time and hospitality. Thank you. Mark Nance
I have a 99 royal star tour deluxe but am struggling to find a kit from what I see they only go to 98 on all of the ones I see, is there not a 99 rebuild kit?
@@geezermoto7820 okay I have yet to pull the carbs but basicly gasket match is the only way to tell? I don't know why the all are labeled up to 98 and then go 00 up on the newer kits.
@@StrongSider23 only way I can get it right Just be sure the slow and main jets are same size after you get the kit. To match your old ones. Or just simply soak the old ones in carb cleaner until they look new and reuse them
Hey I was wondering if you would be able to rebuild my carburetor for my 2002 royal star? It’s been sitting for a few years according to the last owner. Are you able to reach out to me?
Hi, I apologize but I have forgotten your first name and this is a different phone than the one I was communicating with you when I still lived in Utah. I’m the guy that has the 1979 Honda CBX and I have a 1983 Yamaha venture that needs to have the carbs rebuilt on them. I ordered the kit to rebuild the carburetors that you recommended and thought I was gonna have time to do it myself but besides not having the experience I don’t have the time due to moving to a new place in East Texas with 10 acres to take care of. Would you have time to rebuild my four carburetors and how much do you charge? Thank you for your great video and I appreciate you. Thank you. Mark
@@geezermoto7820 I had taken the carburetors off and was going to rebuild it myself but I just relocated from Utah back to my home in East Texas Anaheim so many projects on this 10 acres that I really don’t have time for the carburetors. This will be my first rebuild job of this nature and I can see that I’m gonna be extremely slow because I don’t really have the confidence to do it quickly. I sent you an email but I’m not sure you have seen it yet. What is the approximate turnaround time for you on the four Ventura carburetors? Thank you. Mark Nance
Hello, Mr Geezer. I am looking for Carburetor for Royal Star 1300 part number 4nk-14901-00-00 ( Carburetor 1) but i couldnt find it. Do you know if the carburetor for Royal Star Venture work for Royal Star tour? Thanks
Hi. I’m looking for a carb body exactly like the one the video as someone has broken one of the brackets that hold the flat inside the carb. Any idea where I can get one as I can’t find it on eBay or anywhere else. You can contact me directly as well please. Thanks
@@geezermoto7820 thanks. Any chance you know the exact model number I should be looking for to get this exact style of carb since all the ones I found on eBay for the Royal Star XVZ1300 seem to be different.
@@geezermoto7820 that's what I thought but wanted to make sure it didn't serve a deeper purpose. I had one of them randomly split in half after being hit with an ultrasonic cleaner. Waiting for 2 primary holders. The o-ring for the primary jet. And one of those screws and she can all go back together. Hopefully I didn't forget anything!
The gunk and filth in these carburetors is not from gasoline with methanol, that is from not riding the bike. I have done my share of resurrections on motorcycles that sat with gas in the carburetors for years. Sometimes the slides would be guarded into the Boers of the carburetors. If you are getting fuel past the O-rings leakage, smell the oil in the crankshaft/crankcase area. If it smells like gasoline, don’t even start the bike. Inside the gas tank probably looks the same as these float bowls… Methanol in the gas is corrosive to some plastics.. Harley riders call Japanese motorcycles rice burners. They don’t even know why because every time I saw that sticker on a hog riders helmet, I asked him what it means, and they never know. I know what it means. Along those lines, I hope that other countries don’t start calling motorcycles ridden in America, corn burners, because it would be true, and it doesn’t sound as groovy as being called a rice burner.. this video reminded me of how much I hate carburetors now that I have experienced fuel injection. I was watching these videos because I was considering buying my third Yamaha venture because a very clean one just came up on craigslist. I put 138,000 on my 86 Yamaha venture over 16 years, I put 49,000 miles on my 2002 Yamaha royal star venture which could not hold a candle to the original ventures. I’ve had both, I know.. The third generation of the V4 Yamaha venture is a dog compared to the 1986 through 1991 ventures. That generation of ventures actually turned in the 12 second quarter mile times at the dragstrip. The starventures, I’d be amazed if they turned in the 16 second quarter mile range.. The 1984, 85, and 83 1200 CC ventures were the smoothest. They had problematic second gears if the rider was not deliberate in his shifting. They fixed second gear, in 1986, gave it bigger saddlebags, bigger carburetors, the same clutch that they use in the Vmax, and the 86 on did not have the smoothest engine like the early version did, but the 86 through 91 ventures were the rocket ships. I only sold mine after 16 years because it was getting old, I never had any trouble with it, nothing ever broke.. of course I was a maintenance junkie, I did things like take the driveshaft out to lube the splines. I change the brake fluid and clutch fluid every year, I never ever pressure washed my Venture ever. Pressure washers destroy motorcycles from the inside. They force water and dirt down all the cables, into the electric’s, into all your lights and gauges so they fog up the lenses, into your wheelbearings, into all your suspension linkage, into your electrical connections, never never never pressure wash a motorcycle ever.. when you put them away for winter, fill the gas tank all the way up to the top, and drain the carburetors. Each carburetor has a screw to drain the float bowl at the bottom. Park it on the center stand out of the sun and don’t cover it with plastic. spray inside and out of your mufflers and exhaust pipes with some kind of oil like fluid film, which is actually lanolin, I guess you could call it sheep fat.. $9.98 a can at Lowe’s. I rustproof my new ram hemi pick up truck that cost over $50,000 with fluid film. I took five days taking my time to make sure I rush proof that here in the Northeast. Those ram trucks restaurant in front of your eyes if you don’t undercoat them with some type of oil, not Ziebart tour, you have to spray it with fluid film or something like it that will travel to get where the salt water will get. The Ziebart will harden and it will not travel and it will actually trap water making your car rust faster. Spray that on your motorcycle exhaust system inside and out for winter storage. It will not hurt the bike, you can actually put it on the leather, could actually put it on your skin to soften it. make sure you do not use carburetor cleaner unless you have to when doing the carbs. Because carburetor cleaner is an acid/solvent. never never never use dishwashing liquid to wash your motorcycle or to lube your tires when installing new tires. Dishwashing liquid‘s, most of them have LYE in them. That is extremely corrosive to aluminum. If you wash the bike with dishwashing liquid that has LYE in it, you will destroy the finish of the wheels. If the dish washing liquid burns your eyes, that’s the lye.. only use rubber lube that you can buy at Napa for about $16 a gallon to lube tires for mounting tires, and only use car washing liquid soap to wash your motorcycle by hand. And never use paper towels when cleaning your windshield. It’s like using sandpaper on plastic or acrylic.. to clean your bike up to do a detail job, go to the Honda shop and buy a can of Honda spray detailer. That is the best stuff in the entire universe. You can spray it on a dirty motorcycle and wipe it off and it will not scratch it. I had a Honda pacific coast, black, that I commuted on for 24 years. I never ever washed that bike with water and soap. I only used Honda spray detailer on it, and when I sold it, it still shined, in the sun without the spiderwebs scratches in the finish it will show up on black vehicles. I also use that Honda spray detailer on my expensive guitars. It is the single item that Honda sells most of in their entire inventory. They sell more of the spray detailer then they do spark plugs. You can use it on the vinyl seat, on the paint, and and on your windshield, and it will not scratch, within reason. I mean if you have dried sand on it, you have to hose that off first
