I`ve had mine now for the last 12 years, bought it used (it is a -95) in 2012 and can not find anything else to replace it with. Every winter I look around both used and new options but when spring comes and I start it up and ride away for the first time I always decide to keep it for one more season. It is nice to ride and easy to get along with. And mine has been absolutely bulletproof, no issues at all during the whole time. It is well maintained, and of course tires wear out and have to be replaced and such but no faults. Great bikes!
Yeah, kind of an overlooked bike that just does what it’s supposed to do. Keep it going!
Having had a vn750 for last several years I begin to appreciate newer stuff with fuel injection. Think I've had my last MC carb.
You are 100% correct!
There is a fuel injector upgrade for small engines available. Web search.
Love the leather tank. I remember seeing those in the dealership. The Vulcan/Magna/Intruders were pretty cool back then. Now they look a little baroque.
Yeah, I kind of like the tank cover too. I really hated the look of these in the 90’s but now I have a different feeling…at least they put their own spin on the cruiser look rather than just straight up copying HD.
I love the way those bikes look. I have owned three Vulcan 750s, there is a reason for that. After wearing out two new ones, I bought a super low mileage '97 a couple years ago, and have put 9,000 miles on it so far. These bikes are absolutely gorgeous compared to the flat black TRASH that's out there now. They actually look like motorcycles. The '07 Vulcan 900 Custom in Candy Plasma Blue, silver, and chrome looked great. Then they went down the flat black road with it and completely ruined it.
Thank you for this Video! I recently brought my bike (1994 Kawasaki Vulcan Vtwin) out of storage and was already having issues getting her running. After watching your video and seeing your struggle with the carb, I now see what ill be getting myself into! LMAO Cheers on you for getting her back sounding great!
Hmm, well about that…stand by for round two. My buddy is still having issues, I’m ashamed to say. Will be going back in for more.
Life saver
@@98FutureStar these carburetors are kind of a pain, but I have worked on worse (old Honda V4’s!)
That engine configuration at 55° v angle leaves little room for carbs. Tight fit for sure! The last carbureted engine I worked on was a 2006 Hyosung GT250 as a 75° v twin it
was easy. Used an ultrasonic cleaner & compressed air to remove the remnants of ethanol based gas to get it running right as rain. What a feeling it is when the fruits of ones labor pays off! 😁👍
This bike has been a curse. More issues popping up after my buddy got it home. We will get it working right eventually.
Wish you would had shown removing the jets and putting the new ones in.
Very good video sir. I appreciate anything else you have on the VN750
Yeah, I could/should have made an entire video just of the carburetors. They are definitely different from any others I’ve worked on.
There's a tab on the top of the boot and a tab on the top of the manifold to line up the boots. The clamps have line markings that line up with marks on the boots.
Good information, thanks!
A friend of mine bought a 92 kawasaki Vulcan 750 in 92 and has had it ever since. He hasn't been able to ride for 10 years so it has been sitting there rotting. I have offered to buy it from him several times over the years but he has refused to sell it
He most likely may never be physically able to ride again sue to health issues. I would love to be able to fix it up and let him see it running again but I doubt he will ever sell it.
@@ramonmacias9013 I know of a lot of bikes and cars like that. It’s hard to let go.
Heh, same kit I just bought, I guess it's going in the freezer.
That chrome fender is from a European VN 750. The size of the carb jets will tell you if those are European too.
These carbs work nice but you have to keep them clean. I use Seafoam in the tank if it's going to be parked more than a couple of weeks. Non-ethanol gas will help. Not a fan of dry storage but with the siamesed float chamber, it's probably best to drain these carbs for long term storage, luckily the drains are easy. The gas will evaporate out of the right side carb in two days, and that leaves behind crud. Seafoam a couple of times a season can keep the jets clean.
It's a really fun bike, quirky sometimes, but fun.
There are alignment marks on the boots and you're supposed to leave one boot on the head, check the manual for which one. Best just to do the earshave and get rid of the airbox.
Good information. I doubt that the fender is from the European model though. It doesn’t have the correct mount holes, I am pretty certain the bike was wrecked and someone got a fender that was close to fitting.
Nee to your channel definitely love your videos I'd love to come work on bikes with you
You never know!
rad video, gramps. i wish i had your know how cuz my bike needs all of this
This bike is a bit more of a challenge than others. Really a pain in the ass.
Vermont will register vehicles that are nnot registered a few years. $75 last i checked. Then register in your state as current.
Vermont has recently cracked down on out of state people registering vehicles there.
I'm not used to seeing a gas tank wrapped in cloth like that. Am I seeing that right? 🙈😄
It's always a rare treat to see the 750 cc and 800 cc versions of these on the road.
It’s a leather cover, looks pretty decent but it’s reason there because the tank is not in good shape.
Oh no Captain Tom you fell victim to the Vulcan carburetor pinch.
Ah yes, it definitely got me. Logical!
@@TomsTinkeringandAdventures Yeah, when I saw you start I knew you would be in for a fight. There is a way to wrestle that air box out but I forget how.
Interesting that this Vulcan 750 has Chrome fenders. Most of the Vulcans did not come with chrome fenders. I had a 2005 Vulcan 750 that had a chrome front fender.. I did some research on the Internet and some people claim that they were only optional on overseas Vulcan 750s.? I cannot confirm this but they are rare. Very cool!
And I never saw a motorcycle gas tank that has been covered in vinyl fabric. ??
The front fender was weird, I figured out later that it was not the correct one. The front forks are twisted as well. The tank cover is leather, possibly an aftermarket option but it’s there because the tank is beat up. This bike was wrecked badly at some point.
I have one of those it back fires and I don't really understand the choke when it's down I get more power but when the choke is up it gets less power
@@user-uc5ng8hh7o I don’t remember, up is probably choke on?
Would've loved to see the step by step for the elimination of the Reed valves. Forums are full of owners looking to do the ear shave on their vulcan.
Oh, I thought that this was something that had been covered a lot. I have been doing this for years. Anyway, I just cut a piece of aluminum into the basic shape of the reed valve plate and drilled the mounting holes. Cleaned it up with my belt sander. I'm surprised that nobody offers these for sale, easy to make if you have a water jet or something like that.
Yikes. This is why I like single cylinder air cooled engines. A lot less stuff to confuse me😂
True statement! The V4 bikes are probably the most painful to work on that I have dealt with. Thanks for watching.
Today i use a heat gun onto rubber boots, softened it makes dismantle n install much easier.
Yes, that’s a great way to do it.
I am from Malaysia. Hai
@@chewwanchoon6109 I have visited Malaysia!
I just bought my first vulcan it's a 85 vn700 and I'm wondering why or the purpose of blocking off the air to the exhaust I watched and u said something about back fire and they go after awhile so do you have a video on that process?
The air valves put fresh air into the exhaust to help burn any unburned fuel. I like to remove the system really just to simplify the engine. I didn’t show much of it but there are probably plenty of videos out there about “PAIR removal”
Ive got a 1990 and i had the carb rebuilt. Worked well for 50odd miles. Now its backfiring and has shodding power. Can hold the throttle and the power ebbs and luls almost dangerously. Think i just need a new carb?
No, something still isn’t right in your carbs. We had to eliminate the vacuum petcock on this one eventually, just put a manual one on and a brass T fitting to each carb. Works a lot better
@@TomsTinkeringandAdventures hmmm.. not much knowledge on bikes. This is gonna be a sucky project
@@johnnyboy6429 well that's why I make videos, so people can try to learn a bit and I can help a bit. It's pretty difficult to troubleshoot what's going on from here but I doubt you need new carburetors.
@@TomsTinkeringandAdventures yea its a pretty weird issue. Its very intermittent. Tonight the bike ran very well. Last night it was popping with backfires and when I tries to accelerate it would bog down and then all of a sudden give me power and I'd go flying off when the full throttle suddenly returned. It stalled twice at a light while I tried taking off. Super weird... again I fix cars not bikes. This is all new to me. And I dont mess with car carbs because no one has em anymore haha.
Misturar água com óleo,qual o motivo
Are you saying that your motorcycle engine is getting water in the oil?
Dude I have a Vulcan 750, I'm scared of this carb. Mine is running like shit and honestly I don't think I have the courage to fix this hahahahah
It’s kind of a pain, but it’s worth it to get it running right. You can try running a strong mix of fuel system cleaner in the tank, but I’ve rarely had good luck with that.
@@TomsTinkeringandAdventures Yeah me neither.
I have disassembled almost everything, might as well check the carb. Initially I was only going to replace the clutch, but you know, one thing leads to another.
Now I have all the coolant hoses off (some are broken and it's a pain to find spares), the thermostatic valve is stuck, I was riding with an empty radiator. Surprisingly enough, no damages.
Found some oil leaks that the previous owner tried to fix (very poorly) with glue, some broken o-rings, electric issues, gas leaks, and the list goes on... Old bikes dude
@@kalebribeiro868 yeah, sometimes you go in to fix one thing and end up getting in pretty deep. Good luck with it.
Hey could you possibly tell me what cable is forward a return for the throttle I got the same bike but I gotta install the kit
I have same.problem son bought a bike that has been siting for 10 years im in the proses of trying g to get the carburators out any pointers you can give me. Thx in advance
Patience! Make some “line up” marks on the intake boots, you will have to remove them to get the carburetor out and they need to go back in there in the correct orientation.
If you owned that bike and could sell it for a harley Davidson 2011 street glide would you?????
@@user-uc5ng8hh7o I have heard the Street Glide is nice. Will be bigger and heavier.
seems like all the old japanese bikes have the nightmare carb situation. i've always liked the looks of the vulcan 750, i think it has the look of the early hd lowrider. i've also seen where if the stator fails on the vulcan 750, you either have to pull the engine or cut the frame. ridiculous for changing a part that seems to eventually fail on every motorcycle.
Any motorcycle that sits, no matter what country it’s from, will have carburetor issues. I had not heard about the stator thing, if that’s the case it’s not great. Had to remove the engine on an old Goldwing to change the stator once, lots of work.
@@TomsTinkeringandAdventures I’m not bashing Japanese bikes, just how they jam carburetors into small spaces.
I had an 82 Suzuki Gs 750 that had the usual bank of carburetors and air box typical of Japanese bikes of that era.
No fun trying to get it in/ out of that space. That Vulcan looked to be far worse to deal with. 🥴
Can you do mine ?? Come on man !! I just subscribed bro
I gotta say…I hate these bikes! 😂. Bring it by.
Man I worked on my dads 89 Vulcan 750 for a whole year. Man it was a pain. It was hard getting everything to fit especially the carb, it stopped running in 99, gas froze in the carb and tank. Since then my dad didn’t use the bike or try anything. I finally got it to run, ran perfect. I got everything to complete the bike and it started flooding, now it doesn’t wanna start and if I get it to start it won’t idle… I need help
Sounds very familiar. After I got this one running great, gave it back to my buddy and now it’s flooding constantly and runs terribly. I will likely be doing another video.
@@TomsTinkeringandAdventures alright thank you so much. Our bike only has about 9k miles on it. My dad doesnt ride anymore but i will be most likely using that bike to get around rather than a car sometimes. I rebuilt the carb about 3 times, not sure what the issue could be. Also the bike has brand new ngk spark plugs just like the previous ones. It ran better, I didnt change the wires or coil because for the set its about $60 and i dont think thats the problem. The problem now is that its flooding and the bike will crank, it will eventually start but you have to give it throttle, it wont idle.
@@KhaiMahase seems like a common issue. I hope to figure it out
@@TomsTinkeringandAdventures Did you figure it out lol, currently working on the bike. Got a new petcock. Im not sure which line is for the reserve the left or the right, on the right line I have a inline fuel filter. No gas coming through the filter so i would assume its the other side. I smell gas from the carb. Not sure if its flooding or what its doing. Its probably got either a half a gallon or a gallon of fuel in there. Fuel was kept in a seperate gas tank. Fuel is probably more that 5 months old. That could be why, no clue tho. Bike is running on starter fluid only then dies out. Not sure what to do next.
@@KhaiMahase I have not got the bike back here yet. I read on the Vulcan forums about these carburetors, they are very picky. I’m hoping to get it right for my buddy. The petcock is vacuum operated, no fuel should flow unless the small hose has vacuum applied to it.
pulling 4 connected kehins out of the
V of a magna is a excercise in patience as well.putting them back in is definately NOT for the impatient either. even i let a few *^@!÷~¿☆ fly.& i have plenty of time & patience.
I have only worked on a couple of those. Awful. 😂
Didn't you have a Kawasaki that could only be fixed with an OEM part? These darn Kawasaki's....
Well I don't know if it could "only" be fixed with an OEM part, but it did fix the crazy issue it was having. Yamaha seems to be the way to go?
Vulcan eek these look like like a cyber man out of the British DR Who tv programme I’ve seen prettier😂😂
Yeah, I don’t know about the looks but at least it’s not a HD rip-off.
What an odd little bike!
They really engineered this thing!
Another reason to never consider California
Hmm, all these bikes come with the same stuff.
@TomsTinkeringandAdventures I was speaking in reference to the registration debacle. Anyway thanks for the video. Definitely bizzare carbs I've never seen before. Have same project inline for Sunday.
@@whitenas ah, yeah…some states are like that!
