For those wondering why the fuel was pouring out of the carbs after he turned the knob to "Primary" it is actually not Primary it is Prime! When you turn it to Prime it releases the vacuum and allows the tank to gravity-feed the bike allowing you to prime the carbs for the first run after sitting for a long time or after winterizing the motorcycle. The XJ650s are vacuum-controlled fuel pressure so the engine creates a vacuum pulling fuel from the tank into the carbs. On is your normal use and should be on that for everyday riding and reserve is self-explanatory. I know this video is 3 years old but the video is still relevant for those who are just coming across the video.
@@kevinon4wheels $250!! Nice...I just picked up an 81 "project" for $200 that I will be stripping down and rewiring fully digital. Got us some Diamonds in the Rough my Friend...
I just bought this same bike but mine is running. It is the first bike I've owned and is going to be my project during quarantine and your video is super helpful!
Same here! I got mine a week ago, first bike as well! This has been a great resource for getting familiar with her as I'm running into some issues getting it to start - and when it does, it's only firing on two cylinders. Just finished part 1 of the series, and looking forward to the rest.
Same! The carbs are nasty though. It’s awful to pull them out and make sure they are clean. I’ve pulled them off 2 times and have to again to put them in an ultrasonic cleaner.
i had an 82' XJ650 Maxim as well and that thing ALWAYS needed multiple shots of starter fluid into the air intake to start up. Never cleaned the carbs though. Hey, it kept me paranoid as hell from stalling out, therefore making me a better rider! Great video.
One of my favorite spark plugs, ND Nippon Denso. I have a 3905 miles 1982 750 Maxim, hasn't been run in years, working on it. I paid $200 for it but didn't have the carbs. Thanks for the video.
@@jerrybigrig9475 Thanks for the reply, NO, not yet, I have a guy that's doing the wiring for me and he had to go to the hospital for an operation so another delay.
Cool wee video. Just finished a lockdown xj650 maxim bobber project. Bought it as a USA import last March. Now; Fully service, new battery, new head bearings, new head lamp, new brake pads, slight rewrite, repaint, single leather seat, custom side panels. Runs sweet once off the choke. Just waiting on the UK plate to arrive, then it’s fully road legal. A great little vintage everyday bike. Might even buy another next winter to play with.
@@kevinon4wheels hey Thanks for your reply. I’ve got a few pics and a short video of it completed and running. It’s a lovely old girl and now looks very cool 😎 not sure how I can send pics?
I got the same bike a few weeks ago for $100.00! Your videos have been super helpful so far. Now I just have to sit down with the wiring and I should be good to go! Cheers
It really sucks seeing what was once such a beautiful bike in that condition. I bought a brand new Yamaha Maxim 650 in 1982. It was my first new bike. It was a replacement for my first street bike, a 1980 Yamaha XS400 Special I bought slightly used. Before that I had been riding dual sport on/off road bikes. Yamaha made such beautiful, high quality bikes back then.
Clean the gas tank #1. Take off the carbs and clean throughly #2. Make sure the boots aren’t cracked in which will cause an air leak#3. I just bought a1982 650 xj maxim there real well make bikes !!
I had one of those in 1994, payed $500 for it with about 17k on it. I took it from Northeast PA to California and back. Not very comfortable for long rides but in ran flawlessly even when I had to put 81 octane in it in the middle of Nevada desert. I sold it in 96 with 50k on it and it still ran pretty well. $250 was a steal on your bike.
I have a 1985 Maxim X XJ700 that has been sitting 22-years. I've repaired numerous corroded electrical connections, battery, oil/filter change, cleaned gas tank, replaced fuel and vacuum lines, replaced petcock, and still it took a few tries to get it to fire at all, then when it did the engine ran rough and would just die again after a few seconds. I used to drive the bike long ago, and it was a lot of fun with those 20-valves breathing, but looks like she sat too long. Will tackle the carbs next. Fingers crossed.
I just bought the same bike today and harder to find videos on the xj700. Runs great and was well takin care of. Any tips for the future or what I'm in store for?
I just scooped up one for 300! I’m so excited! It supposedly runs and drives, has a bad battery and slight fuel line leak, but it will be a good first bike and project bike. I can’t wait to get it to my house soon.
Kevin On 4 Wheels update: petcock is in terrible condition, I’ve had to pull the carbs 2 times and will again because I just got an ultrasonic cleaner (throttle is sticking) some specific seals are really tough to find and are expensive, but it’s not a bad bike to work on! I fixed the valves and took it out for a 20 mile spin. It’s an amazing bike!
Good man. I bought one outta a ditch. Great bike to work on. Ive mine stripped and just working on the engine now. Do yourself a favor and dont run it too much or at all preferably. Most likely the primary chain is flopping and cam chain also See Mezzmo Engineering videos. Great videos for this bike. Any helo just ask me too. Have a good one
I just watched mezzos videos on the engine tear down I had to replace to springs and caps in the starter clutch required a full engine tear down mines the 750 though
Hello. It ran decently 2 years ago. I have had it in storage and need to get back into it to get all the nip and tuck done. But I am definitely going to zero in on cylinders 1. Thank you for bringing it to my attention!
just got a super clean 750 maxim with a damage blinker for $1000, needs a battery and the spedo doesnt work but it is super nice, picking it up this friday!
This problem I got with a 1983 Yamaha 750 seca. What was sitting for more than 2 years, the first thing I got stock in was the carburetor been completely block out. So I started to work in service carburetor completely. all jet nozzles where completely clogged n rusted, even treadles in the carburetor didn’t even move.
I picked up a 750 last year for $500 with title. Pretty much same condition but still needs some issues addressed. When it comes to carbs not running right, honestly thes best thing to do is just to clean the carbs out. That throttle body cleaner stuff or any other home remedy won't really solve the main problem by just spraying into the intake..
I use Marvel Mystery oil . I let it set overnight in the tank and carbs. It's never failed on old bikes for me. I also mix alcohol gas and oil for the first 20 miles. Drain and ride.
I have an opportunity to buy a 1982 Yamaha 650 Maxim excellent condition only 2400 original miles one owner, the old man passed away, his wife selling it for $2000 . But it's been sitting for about three years . Looks damn near new . What would be a fair price to pay ?
That’s a nice find. Well, consider the title process to make sure you can transfer it ok. I think 2,000 is high even for this crazy market. You’ll prob need tires outta the gate if they’re old and dry rotted. I think $1,500 might be “fair”. $1,200 would be better
13:45 Yeah, I'm gonna ask you a question. Where could I get? A vow head overhead valve boat for the passenger side topping on the cap. I'm missing one. Where could I go get one at and what would the car brighter sit if I rebuilt him? Cause he would have straight dirt and rushed. In and I took the jets out and cleaned them and put them back in. Could you tell me what the terms are on the car? Drivers was not didn't have a gasket or it was rotted or something, and I replaced it, and number one piston that would be on the left side was all dark and kind it looked like. I don't know, like a goldfish look like it was getting old cause.I guess it's licking old or it wouldn't get the right mixture of air but the bike was running on three
Just yesterday I picked up a xj1100 for a reasonable price. It didn’t run for few years now. No keys. I am really debating should I sell and try to make sum money or should I try to fix it 🤔.... it looks very clean. First bike so Im afraid I may bite more than I can chew. So here I am searching the net to find the answer...
That’s a tough call. It’s always a gamble. I feel if you have a decent bike that you will enjoy learning to wrench on stay the course! But if aren’t interested in the hard knocks, you can make a profit then buy something running!
These bikes are bombproof, except for the carbs, they need some care but once stripped and cleaned properly and set up right you will have the most reliable bike you could wish for. Your pilot circuits are clogged by the way
Basically got the same bike mines the 85 xj750, I started it up one day, was running alright, then it started to make a gurgling sound, kinda bogging out, then had oil looking from somewhere, Bo cracks in the block or anything, any ideas? It's sat for 2 years cuz I'm stumped on it but I want to get her back and running
I still own a 1982 Maxim XJ650J that I bought new in march 1982; it has only 6387 kilometers (canadian equivalent to 3966 miles) Runs about one or two hours per year. Any collector interested ?
I just bought one for $300. Put a new battery in and I did not get lights. Brand new to all of this. What’s the next step? I’m assuming it’s an electrical problem.
I used to have the 700 maxim x for a little cruiser it left many open mouthed how quick of the mark they are sold it to a friend who then totally destroyed it in a smash
5 years ain't nothing, the xj I got last year hadn't been ridden, registered or started since 1993, they are easy to get started, making run right that's a whole nother story, so you are planning a series on restoring the xj, good luck with that because there ain't none of the important new parts available, well unless you live in aussie land, i was just talking to someone down under and they were able to get all their timing gear, guides chains ect right from the local dealers shelf, there ain't none of that stuff her in the US except the NOD stuff you can find on ebay but the idiots selling the stuff think they have the rarest most valuable parts on earth. IF YOU NEED A REPAIR MANUAL LET ME KNOW I'LL SEND YOU A DIGITAL COPY....
Hello my father just bought this bike could you please send me the manual? Jessicaschooladdress1@aol.com I’d truly appreciate it! The bike is shorting straight to ground and the battery’s brand new yet not able to get the bike charged even when the battery is fully charged the bike is sucking so much amperage to start and just draining the entire battery immediately. We’re praying it’s not an alternator problem because we did have it running when we jump started it. But when we got the new battery now it won’t even start. But anyways the manual would be of great help!
Hi friend, I just got a 1985 xj750xn and can't find any good service manuals for it online, do you happen to have any leads on a manual for that year/model? Thanks and safe travels
I have a question hoping you might be able to answer for me. There is a hose coming from the intake compartment that leads to the air filter. If you go to 18:05 and pause I can show you what I mean. Now you see the gas line hose and to the right of it underneath that black plastic intake cover (sorry lack of better word) is another hose coming underneath, you can see the clip and the hose heading downward. Now on my bike this hose has become disengaged and I can't figure out where it connects to, I have looked all over. Could you please tell me where this goes? I would think it cycles back into the engine as it did have some oil coming from it. thanks
HandNrocK ok I think. I got it figured out. I believe that is a drain hose for the air box. In the event it gets flooded it will drain out so the intake won’t suck it in. It should be hanging unattached to anything. I think that’s those you were looking at? Let me know!!
Grant N thank you! It’s been fun to stumble through it. I see the oil capacity question was answered. It’s great they do that so you know what to buy. Wish lawn mowers did that. Ha ha
You scored an easy bike to keep running once you work thru all the neglected fuel and wiring woes you have here. Scare a manual up and run thru the numbers, starting with the electrical segment. It totally lost signal in the video. That's going to leave you stranded some day. Best of luck on your bike.
@@norwichcomputerrepair939 liquid electrical tape if they're not so bad that you need to replace them. Feel them inside and out and you'll know what to do by how bad it is
@@kevinon4wheels Also when all the power cut out on you and magically turned back on i took out the main fuse and sanded the metal bits on the ends and havent had a problem since
I noticed after the fact the intake manifold was dried and cracked. That caused the whistling in one of my videos. I bought new ones for hardly anything but I snapped off the stud on the first bolt. So needless to say a little RTV fixed it for now. Touch all 4 exhaust pipes when it starts up so you can make sure all 4 cylinders are firing. Other than that it's pretty straight forward!
Damn, you're doing everything you should NOT do. It's a miracle you have'nt blown up your garage yet. I've been fixing motorcycles for over 10 years, and did about 100, including a couple of maxim's. The way you are doing this is very wrong and dangerous. Oil spraying, gas leaking, it's a disaster. Don't try this at home people! If you get a bike that has been sitting for 5 years, make sure not to start it. Clean the carbs first, change the oil and the spark plugs, make sure there are no leaks, and after all that.....then you start it. And try to keep your workspace clean, cause this is just horrible.
Hi..Kevin.I am from India..I need some help I would really appreciate if you could help I have Yamaha secaxj650 1982 which wont start..did the way it wasrequired but still no luck..your video is good
Hello. I'm not a professional, but I try to narrow it down to electrical or fuel. Did you see if you have spark? And if you did have you looked at your carbs?
You're not kidding. I tried forever to get everything lined up and pop in. Wasn't happening.... I found it easier to buy 4 cone filters and rejet the carbs instead. Ha ha. It was worth it
Pods are a nightmare with these carbs, runs much better with the air box. There are several tricks for fitting these carbs, head over to xjbikes forum, you'll find all you need to know
No, not homemade. They were fitted as standard on Maxim and Seca XJs. If you don't like it please send it to me, I've been trying to get one for my Seca for years
Correct, it is Factory, and it takes the same Factory ignition key to the bike. Same as gas tank, and helmet/seat locks.! All off same factory Yamaha key.!! 😁 It's a tire/frame lock so it cannot be rolled away, or stolen easily. It's just locked on a pin welded to the frame to keep it inplace, and has a identical pin on the other end of the protected chain to lock it to itself once wrapped around what you secure it to. It's genius really, and how it neatly packs up in that little plastic cubby hole, and then locks back to the pin on the frame so it can't fall out and you can't lose it It's awesome I used to use it all the time.! 😁 Rough areas at night.! I bet all it needed was a bit of penetrating oil in the lock and key hole to get it to pop open with the key. Too bad you cut it off.! 😞 I have had my 82 XJ 650 for 20 years and still Love it.!
The factory helmet lock is on the right side, with the seat release. Turn the key to the Right, to pop the swing down U shaped lock to put thru the helmet strap, or metal rings on chin strap, to lock it to the side of the bike by pushing it back up to lock it. And turn the key to the Left, to be able to pull the lever to pop the seat off. Hope that helps.
@@jerryking1434 no I did end up selling it to a kid in the city for a couple hundred bucks though so I'm riding on it a month later so I felt good that he was able to make something out of it. I now ride a Honda vt1100

5 years ain't nothing, the xj I got last year hadn't been ridden, registered or started since 1993, they are easy to get started, making run right that's a whole nother story, so you are planning a series on restoring the xj, good luck with that because there ain't none of the important new parts available, well unless you live in aussie land, i was just talking to someone down under and they were able to get all their timing gear, guides chains ect right from the local dealers shelf, there ain't none of that stuff her in the US except the NOD stuff you can find on ebay but the idiots selling the stuff think they have the rarest most valuable parts on earth. IF YOU NEED A REPAIR MANUAL LET ME KNOW I'LL SEND YOU A DIGITAL COPY....
I’d take a copy if you would be so kind!
Hello my father just bought this bike could you please send me the manual? Jessicaschooladdress1@aol.com I’d truly appreciate it! The bike is shorting straight to ground and the battery’s brand new yet not able to get the bike charged even when the battery is fully charged the bike is sucking so much amperage to start and just draining the entire battery immediately. We’re praying it’s not an alternator problem because we did have it running when we jump started it. But when we got the new battery now it won’t even start. But anyways the manual would be of great help!
I would greatly appreciate a copy as well
I was just given one of these bikes. It's my first road bike and I'm really excited to get it going. Any chance you could send a copy to me please?
Hi friend, I just got a 1985 xj750xn and can't find any good service manuals for it online, do you happen to have any leads on a manual for that year/model? Thanks and safe travels
Got a 81 I’ll be taking from Ohio to cali
at 1:31 that is a bike lock insert key and it pulls off a post .

Thank you
@@kevinon4wheels your welcome 👍
I have a question hoping you might be able to answer for me. There is a hose coming from the intake compartment that leads to the air filter. If you go to 18:05 and pause I can show you what I mean. Now you see the gas line hose and to the right of it underneath that black plastic intake cover (sorry lack of better word) is another hose coming underneath, you can see the clip and the hose heading downward. Now on my bike this hose has become disengaged and I can't figure out where it connects to, I have looked all over. Could you please tell me where this goes? I would think it cycles back into the engine as it did have some oil coming from it. thanks
HandNrocK hello! I’ll take a better look today. First though is it’s a crankcase breather hose for emissions purposes but Ill look around in the area!
HandNrocK ok I think. I got it figured out. I believe that is a drain hose for the air box. In the event it gets flooded it will drain out so the intake won’t suck it in. It should be hanging unattached to anything. I think that’s those you were looking at? Let me know!!
Why does the video show 2500 cc on the engine case. Just curious because I bought a new 650 Maxim in '82 and it was stamped 649?
Nice video by the way. I learned a lot and enjoyed looking at my old ride!
An engine oil capacity.
Grant N thank you! It’s been fun to stumble through it. I see the oil capacity question was answered. It’s great they do that so you know what to buy. Wish lawn mowers did that. Ha ha
newbie or what! still, we all started somewhere
that cm3 number is oil capacity marked by the clutch on the engine case engine size is between the pipes on the front of the engine
You scored an easy bike to keep running once you work thru all the neglected fuel and wiring woes you have here. Scare a manual up and run thru the numbers, starting with the electrical segment. It totally lost signal in the video. That's going to leave you stranded some day. Best of luck on your bike.
Thank you! It’s been a fun learning experience
Just got one for my cafe
if you dont plug the vacuum line to the petcock it creates a pretty sweet vacuum leak lol im surprised cyl 3 even ran.
I am amazed too. I was running on 2 cylinders for a while until I rebuilt the carbs
I found cylinder 1 had a crack in the boot. I could manipulate it to make the chirping stop and start

How you fix? I've heard shrink wrap around the boot works

ARE YOU RUNNING AND RIDING IT ..??
Thank you!
Its a bike chain to lock the tire
Thank you!
@@kevinon4wheels i had just baught the EXACT SAME BIKE and was having the same problem just rlly trying everything to not take off the carbs
@@kevinon4wheels Also when all the power cut out on you and magically turned back on i took out the main fuse and sanded the metal bits on the ends and havent had a problem since
@@jonathanmayotte3305 it’s a bear getting those things on and off. Ha ha
@@jonathanmayotte3305 that’s a win! All of mine snapped off ha ha
Hey so im looking at buying one can you give mw any tips on what to look for
I noticed after the fact the intake manifold was dried and cracked. That caused the whistling in one of my videos. I bought new ones for hardly anything but I snapped off the stud on the first bolt. So needless to say a little RTV fixed it for now. Touch all 4 exhaust pipes when it starts up so you can make sure all 4 cylinders are firing. Other than that it's pretty straight forward!
Another bike...
Damn, you're doing everything you should NOT do. It's a miracle you have'nt blown up your garage yet. I've been fixing motorcycles for over 10 years, and did about 100, including a couple of maxim's. The way you are doing this is very wrong and dangerous. Oil spraying, gas leaking, it's a disaster. Don't try this at home people! If you get a bike that has been sitting for 5 years, make sure not to start it. Clean the carbs first, change the oil and the spark plugs, make sure there are no leaks, and after all that.....then you start it. And try to keep your workspace clean, cause this is just horrible.
Lol, holy fuck Nancy. You ever get anything done while obsessing over other men
Mine burns oil what would that be
Top of my head, I’d check compression, overheating,and possibly too light weight of oil.
How many gasoline spend in 100km?
Hello. Depending on riding style (and my conversion to the metric system) I average 10 km per liter
Hi..Kevin.I am from India..I need some help I would really appreciate if you could help I have Yamaha secaxj650 1982 which wont start..did the way it wasrequired but still no luck..your video is good
Hello. I'm not a professional, but I try to narrow it down to electrical or fuel. Did you see if you have spark? And if you did have you looked at your carbs?
If you think you have problems now just wait until you have to take the carbs off. My XJ750 is a bitc* to get off and worse to get back on...
You're not kidding. I tried forever to get everything lined up and pop in. Wasn't happening.... I found it easier to buy 4 cone filters and rejet the carbs instead. Ha ha. It was worth it
Use ratcheting straps
Pods are a nightmare with these carbs, runs much better with the air box. There are several tricks for fitting these carbs, head over to xjbikes forum, you'll find all you need to know
It’s running tho
What is oil that u flow in machine?
Hello. I used Honda GN4 10w40
I think that was supposed to be a homemade helmet lock?
I think that's what I ended up deciding too! No key, so it had a date with the angle grinder
No, not homemade. They were fitted as standard on Maxim and Seca XJs. If you don't like it please send it to me, I've been trying to get one for my Seca for years
Correct, it is Factory, and it takes the same Factory ignition key to the bike. Same as gas tank, and helmet/seat locks.! All off same factory Yamaha key.!! 😁 It's a tire/frame lock so it cannot be rolled away, or stolen easily. It's just locked on a pin welded to the frame to keep it inplace, and has a identical pin on the other end of the protected chain to lock it to itself once wrapped around what you secure it to. It's genius really, and how it neatly packs up in that little plastic cubby hole, and then locks back to the pin on the frame so it can't fall out and you can't lose it It's awesome I used to use it all the time.! 😁 Rough areas at night.! I bet all it needed was a bit of penetrating oil in the lock and key hole to get it to pop open with the key. Too bad you cut it off.! 😞
I have had my 82 XJ 650 for 20 years and still Love it.!
The factory helmet lock is on the right side, with the seat release. Turn the key to the Right, to pop the swing down U shaped lock to put thru the helmet strap, or metal rings on chin strap, to lock it to the side of the bike by pushing it back up to lock it.
And turn the key to the Left, to be able to pull the lever to pop the seat off.
Hope that helps.
Literally got a 650 today for FREE on the side of the road. Needs a CDI, plugs, battery and tires.
Blacky Chan great score!!! They’re fun
@@kevinon4wheels hellyeah they took like it!!!
Did you get it running properly ...???
@@jerryking1434 no I did end up selling it to a kid in the city for a couple hundred bucks though so I'm riding on it a month later so I felt good that he was able to make something out of it. I now ride a Honda vt1100
Pray your starter clutch don’t go out on that engine

Not as bad as a virago.

@@zacharylantzy2966 you’re welcome!
that’s too bad you didn’t pull the carbs first to clean or check them out. all that gas went into our drinking water.
I got one of these headaches.
Ha ha. It's a labor of love for sure
sounds like you have given up already
