XJ650 - headlight and instrument cluster correct?

Just picked up this 82 XJ650 and was wondering if the headlight and instrument cluster is correct or if parts on this bike have been replaced. The only pictures I have found for this year XJ650 has the round headlight while this bike has rectangular. The tail light also has a light on top to shine on the license plate mounted to the back of the seat rest which I suspect might be from another bike like a Seca?
Images attached.
Are the controls and handle bars correct?

Any chance the bars, gauges, etc from an 85 XJ750 would transfer right over to replace these?
It looks to me like the gauges, lights, controls were swapped over from another bike. The signals are not working correctly as the right front signal lights up but does not flash, the left light does not light but you hear clicking from the relay and the left side front does light up when the high beam is turned on but does not flash. Seems they screwed up the wiring.

 

Looks like you have a 750 maxim
Check the engine cylinder just below head gasket on the front between 2amd 3 head pipes tells you cc of engine

 

You are correct, it appears to be a 750. The number on the engine says 748.
The seller thought it was a 650 and that is what is says on the title, I will have to verify the VIN number to the title to make sure we got a correct title.

 

You git a nice looking 750 Max. The red on the gauge faces hasn't faded to all white.

 

The Vin# on the parts catalog above is almost identical to the vin number on the bike. So it's definitely a 750. I can't say I'm overly thrilled with the handle bars, headlight or the instrument cluster. I am hoping that we can swap out the handle bars and instrument cluster from our 86 XJ750. She's not running and even though we did get her to start up and run last year she just needs more work than I have time to put in. SO I'm hoping we'll be able to take the two bikes and make one kickin bike.

 

First thing I do before I hand over the cash does the paper match the bike and I want id !

 

The paper matches the bike. My fiance was mistaken. He thought that the title said it was a 650 but it doesn't say that anywhere on the title. In fact it has no model ID number on it at all. Just that it's a Yamaha and that it's classified as a motorcycle. The VIN number on it matches the numbers on the bike perfectly.

 

It is definitely a 1982 XJ750J Maxim.....Your VIN stamping around the oil filler hole probably indicates 15R- XXXXXXX

 

Thank lucky stars I was worried you might get screwed

 

YES EXACTLY!

 

The seller advertised it as a 650 and thought that it was but as we discovered, it is a 750. Good deal for us.
Now if I can figure out these pesky turn signals.
They were miswired. A previous owner had cut the plug on the headlight and put in a two wire HID lamp. They apparently had the signals unplugged at some point as the left signal had one of it's wires connected to the yellow green output bullet connector from the headlight plug. So when you turned on the left signal nothing happened. When you turned on the right signal you could hear the flasher relay clicking quickly. When you turned on the high beam the left turn signal would come on.
I now have the bullet connectors back in what I believe to be the correct locations for the signals but now if you turn on the right or left signal the lights will come on for that side but not flash so something is still not working. I do not know if it is the flasher relay, the self canceler unit or something else wrong. The relay throws when power is applied and holds for a second then lets loose but it does not continue to cycle. Not sure how else to test the flasher relay.
Somewhere on here I read that someone had come up with a way to use an aftermarket flasher relay and still maintain use of the self cancel circuit but I have not found those details yet.
I do not know at this point if introducing a different flasher relay requires any modifications to the wiring to bypass the self cancel or if attempting to use a different relay might cause the self cancel to burn out, etc.
Anyone have info on this and troubleshooting these turn signal issues in general?

Thanks.

Most definitely a 750 Maxim. Seems you found out by now, but it's obvious right from the first pic:

750 maxim clip-on bars, 750 maxim cluster, 750 maxim side covers, 750 maxim seat, shocks, mufflers, footpegs, dual-disc brakes, peg mounts, grab bar, tank...........all 750 maxim. Almost all of that stuff won't fit on the 650 maxim because of frame differences (there are some things that WILL fit, but not all)

The front turn signals are not correct, though..............those should be the round turn-signals.

 

Little confused by some of the explanation but if it is just a situation where the flashers illuminate and do not blink then check the bulbs. As Hogfiddles mentioned, those are not stock turn signals. Many of the aftermarket signals come with lower wattage bulbs than were originally supplied. For the flasher to operate, both the front and rear bulbs need to be 27 watts.

 

OK. Here's a question for you guys. Is it possible to change out the handlebars on this baby? I seriously dislike these. They're old and boxy looking. I want something sleek, shiny and pretty and those certainly are NOT it. I can live with the instrument panel but the handlebars make me feel like this bike looks like an old dirt bike. I love the handlebars on our 86 XJ and our 86 Shadow. I'd like to have something more like that.

 

You might be able to install traditional bar mounts. It can be done on any bike.
Do you have a used parts place nearby? Take the upper tree off and see what might match the holes on you original tree like the ones from 750 seca

 

You'll have to swap out the top clamp. Yours is specifically for your bars.... The other 750 maxim with the straight-through bars will have the clamp you need.

 

We have an 85 XJ 750(which you can sadly see in the background on one of the pics above) that isn't running and we're planning on using her parts as much as possible. I looked at the trees on both and thought that maybe, just maybe, I may be able to swap them out but wasn't sure.

 

+1 and lots more bike for the $.

The top yoke doesn't have to be removed. The bar mounts on the 750 Max are bolted to the top yoke, and the 750 Seca bar mounts swap right over.

EDIT. Never mind. I hadn't noticed the year. Dave is correct.

 

Not always true....

 

Yeah, that's what mine looks like where the handlebars mount. At first I was planning on fixing this one up and tricking her out but then when I REALLY thought about it, I decided I love the 85 too much to pull parts from her and sell off what was left of her. So our plan changed. I'll more than likely just ride this one as is til we get the 85 rebuilt and then we're planning on parting this one out and using the engine for a special project my fiance came up with for a custom built 3 wheel. Thanks for your help!

 

I did finally get them working. Found one rear signal was plugged into the the wrong side wiring and one was disconnected. Combined with putting a full charge on the battery I got everything working.
Although the bike would start up easily on the charge it had, the flasher relay was not responding when turning on a signal but after putting the battery on the charger overnight the flasher began working and I was able to correct the rest of the wiring so now all is working.
I will have to go through the bike and clean up all the electrical connections as the battery seemed to have plenty of juice to run the signals before but dirty contacts may have prevented it from getting enough until the battery was topped off.

 

hogfiddles....not true on turn signals........an '82 XJ75oJ has rectangular turn signals as stock.....not round as you suggested above....

as to those handle bars.....that is one of the features i really like.....but to each his own i guess.....

 

Well, I guess I see enough of both styles on 750 maxims to say we're both right.....

 

sorry, if you saw round ones on an '82 XJ750J Maxim, they were changeovers. rectangular was stock for front and back turn signals

 

Ok
