Hey there, I went out and picked up a 750 Maxim today. Checked it for spark before I paid the guy. I get it home, drain the fuel, put in new spark plugs, poured a little gas down each cylinder, hit the start button, it turned over and started.
Ran for about 1 minute, then quit when I hit the starter button again. The warning light came on, and now it will not turn over at all. The lights work fine, the blinkers are OK, the horn works, it just will not start. Any help?
Bought a 1982 Maxim 750 from the neighbor in May for 300 dollars.. the bike had 15k original miles. I put two new tires and clean brake fluid in it.. drained the gas and cleaned the jets... Wow, what a great bike! Now I just have to undo the aftermarket light assemblies...
This bike does seem to run up into high rpms (runaway choke?) when the choke is engaged.. I'm sure there are some minor adjustments to be made... anyway I'm learning, was never gonna get another bike but for 300 bucks? Anyway, she's very very clean, garage kept... how much is she really worth?
Had a 1982 Maxim when I was young. Wish I could find one in great shape. Nice bikes.

Just bought a 750XJ Yahama Maxim. Have been looking for a rightside cover for weeks now with no luck. PLEASE tell me where I can find one new or used, the color does not matter...
What did this cost, and what type of fuse box did you use?
I just bought an 82 XJ 750 with 31,*** miles, and it has started ticking like a rock is contacting the cover. Any help?
And there is a grinding/howling sound at 45mph coming from what sounds like the gauge area; not sure where exactly.
Any help, email me firstname.lastname@example.org
You may have too much choke on. Really, it will do this too.
I have a very nice XJ 750 1982. I have recently turned this into a sweet little bobber, and am having some problems with the turn signals. I have changed the stock style rear bulbs out with LED. When they are turned on, they just stay solid. Does anyone have a fix for this? I believe I need a different flasher relay for bike. Can you direct me to where to get one?
Well it sounds like you need to replace the clutch disks; it's too far worn out for adjustment.
Yes, you are right.. the spring goes on the shaft for filter housing... think it's just to help seal..
Mine did the same... How did you fix it?
It sounds like you may have an air leak somewhere. First check to see if the carbs are seated properly to the rubber boots. If that's good, check for cracks in the boots, and if that's OK, maybe the gasket between the boots and head are leaking. It should be fairly easy in either case to fix.
Hi, please can someone help me on this issue.
I have a 1982 XJ750 Maxim, and I have changed the front and rear flashers to LED lights, but the flashers won't work, however they do come on. So I re-installed the original lights to see if they worked, and they do the same (come on, but won't flash), so is this the turn signal unit under the tank that is broken?
The 82 XJ750 has been noted for that signal light problem.
First, try running your RPM up to see if it starts flashing; sometimes there isn't enough power to make the flasher operate. I traced this problem to the connector midway under the gas tank. The connections corrode (you will notice the white plastic is dark brown where it gets hot) and it gives a poor connection. I bypassed the connector and soldered the wires for a good connection.
It may be tough to change just the flasher, considering it has a canceller built into it. Try cleaning the connections in the plug under the tank first.
The 82 XJ750 does not have a choke, it uses an enricher valve on each carb (looks like the needle valve on the float). It opens up and dumps raw gas into the carb (makes it run rich), simulating a choke. The farther the choke lever is pushed, the farther these enricher needles open, and the more gas they let into the carbs, and the faster the engine runs. Try pushing the choke lever off and the RPM will drop. Also, look on top of the carbs, next to the cylinders, and see if they are closing all the way; you may have to adjust the cable. They are also noted for sticking if the bike has sat for several years.
I bought an 82 750 Maxim with 18000miles. Runs and drives great, $700, all stock, really an advanced bike for '82.
Fuse box and heat under the seat caused some problems. I just ditched the box, bought modern in line fuse holders, and wired up... works fine now.
Have had it about a year now, and just take it on mainly slow country road runs, but when coming out onto the big road, and no one's around... the old boy has some testes, moves right along, and I was used to a 903 Kawasaki 30 years ago.
At 18000 miles, I'm hoping to keep it going for a while... it's plenty fast and nice enough for me.
I bought my 82 750 Maxim 7 years ago for $800.00 with 18,000 miles. It now has over 100,000! I don't have the exact mileage, as the speedo broke while doing an Iron Butt ride around Lake Huron.
I have not done any major repairs. I did just recently put on a new stator, rectifier, and brushes. The clutch is all original, and finally failed on me yesterday. This bike is rock solid, plenty of power, and still gets 45 MPG!
Sure, some of the lower gaskets are seeping a little, but I don't see any modern bikes even coming close to this thing's reliability. Keep on the maintenance, don't dinker around with stuff, and if it ain't broke, don't try to improve it.
Just changed oil on my 82 Maxim. Had the same problem as a previous commenter. Took the cover off; the filter and the spring fell out. I assume the spring goes between the filter and the cover. Right?
If you got the flasher problem fixed, cool. If not, the LED's don't have the amp draw to heat the flasher up, which is why it doesn't flash. I did the same thing. You can buy a new flasher for LED lights at an automotive parts supplier like Autozone, but I got mine at Advanced Auto.
That spring goes to the oil filter... LOL. Don't feel bad. It holds your oil filter in.
You want to check for air tubes on each side of the carb. Also you could have a hole or crack in the intakes. Otherwise your choke assembly could have issues.
My XJ750 is hard to start in the cold, or if it sits for more than a week unless it's above 70 degrees.
I have a 82 Yamaha XJ750 Maxim that I am restoring. I need the right side battery cover. Anybody know where I can get one?
I know your comment was two years ago but maybe this could help someone else reading. There is a wheel located between the number 2 and 3 carbs; it's your idle adjustment. Counter clockwise turns down the RPM, and clockwise ups the RPM.
Bikez.com has all the info you need for these. Just go down their list of Yamahas.
You need to have a bigger draw; most make the mistake in going low amp draw LED, and find also the charging system may not like it as well. Go back to regular 1156 or 57.
I'm having the same problem. I've been looking for one for over a year and a half; it's just best to make one out of sheet metal with some shears and spray paint.
Just bought a 1982 750 Maxim with a little over 5000 miles on it. The bike runs great and is all original. Just have a little trouble getting used to the clutch; real touchy, but a great riding motorcycle. Fast and nimble around town.
Look on eBay, they are on there all the time.
I bought my 82/XJ750 Maxim last summer. I cleaned the carbs, bought a new battery, and the baby was on the road and running great. Unfortunately it was short lived; it starts fine, I can raise and lower the RPM just fine, but I put it in gear and hit the throttle, and it barely moves. I can get up to maybe 15mph. If anyone could help point me in the right direction, that would be great.
