What Is Missing Or Is It Worth The Build?

I just recently purchased a 1982 Yamaha XJ650R Seca project bike.Upon further inspection it is missing a good number of electrical parts and I don't know what all is missing. I need some help and advice with figuring out exactly what all is missing. Below are pictures of the wiring harness and empty connectors. As of right now I do know I'm missing a rectifier, ignitor, ignition coils, and of course a battery Any and all advice or comments are welcome. Thanks for any help!

 

you could do minimum wiring

82 Seca you say have you checked the vin? link for vin check http://www.dissingermoto.com
on frame and motor ?
that is a YICS Motor I do not belive that is a stock motor for XJ650RJ

1982 XJ650 Seca USA : 5V2
1982 XJ650 Seca Canada: 5V3

you should see 5V2 on the short vin on motor

 

got more photos

 

Early arrival 82’s didn’t have yics engine those where silver bikes( had a new one August 81)
Later “Red” Canadian xj650rjc had yics motor “15U”
But the brake fluid sticker on steering neck makes me think it’s a 750 seca

 

XJ550 I will definitely post more pictures if it will help, and I'll check with the vin first thing in the morning.

 

Yes. The seller wasn't able to give me the full background of the bike but the Odometer has a good 63,000 miles on it so I'm assuming this bike has gotten around quite a bit. But the covering panels do say '82 XJ650R Seca. but I'm not sure if they are the originals with it. So at this point I'm not really sure what it is, but can say for a fact that it is a Yamaha.

 

Bingo!

 

Looks like almost all the electrical accessories are missing (besides that one cube relay, and it may not even be the correct one but would need more info about it). So you'll need: TCI, Regulator/rectifier, fusebox, flasher relay, self-canceller, neutral relay, headlight relay, ignition coils, maybe the starter solenoid too.

https://www.xjbikes.com/forums/threads/the-ultimate-relay-switch-sensor-and-diodes-guide.27543/

Flasher: near the steering headpipe, on right side frame rail, under the right side ignition coil.
Flasher canceller: under the rear of gas tank.
Starter motor solenoid/relay: attached to and behind battery box.
Starter/Ignition cut-off relay (no color): behind coils, behind self-canceller.
Sidestand (kickstand) relay (blue): frame bracket outbound of LH frame tube, just behind the left side ignition coil.
Headlight relay (yellow): behind the left frame side cover, on the plastic regulator-rectifier mounting plate.
Diode block: inside the headlight housing.
Neutral switch: in a hole in the bottom of the crankcase, just "outside" of the oil pan, on the bottom of the engine, up inside a recessed "well".

 

See if you can get it running first, then decide. Sadly, you'll need most of what chacal listed there for just that - bar neutral relay and the headlight and indicator stuff.
Add to the list if you're going ahead with it the backboard for the tci and regulator.

 

You may have purchased a parts bike to go with the new seca you are now shopping for...

 

Yeah thats what I feared it was.

 

Look on eBay for a Wiring harness , that has not been hacked , or xj4ever might be able to hook you up. Suggest you get the wiring diagram out of the manual and get a blown up copy (easier to read) and trace wires ...and agree with Chacal your missing several items .

 

So you think it may be a 750 and not a 650? I'll post more pictures and check out the vin number to come to the bottom of this. If I do go forward with this, I wouldn't want to be purchasing the incorrect parts to begin with but I did take a walk around of it and eventually found the solenoid still attached to it. And I believe the previous owner or owners removed the fuse box and added the black fuse holders.

 

That's how I found this forum was when I was searching for the wiring diagram. So thankfully I did find it on here and saved it. The wiring harness is probably a good route to go with when I take into consideration of how much is missing. and any help would be greatly appreciated. Thank you to everyone who has helped me so far!

 

That's what my main priority has been. I would like to have it running to at least know what I would want to do with it, but if its too far gone and not worth the trouble, then I would just sell it as a parts bike.

 

Need to know if it’s 750 or 650 ?
A pic of front wheel and brake setup and engine number. I have a ton of parts for xj’s

 

I located the vin number and its unusual. it doesn't start with a 5V2 or a 5V3. It starts with 5G2


So I checked it out, and its saying it is a !981 XJ550 Maxim USA.

 

I'll definitely send you some pictures of it as soon as possible. And if you can help with the parts, I'd be thankful for anything that you can sell me with.

 

It’s definately not a 550 Maxim, the bike in the pic is a shaft drive and the 550 Maxim would’ve been a chain.

5g2 should be a 750 Seca.

 

5G2 is a 750 seca

 

I agree. There is no way it can be a 550. You can tell it is a DOHC

 

The 550 is a DOHC as well. Main difference other than displacement is chain drive vs. shaft.

 

Awesome! Thanks, and I will be posting more pictures soon to see if there is any more that you all could help me with.

 

If you look at the front of the engine block between the middle 2 headers, the displacement is cast right into it. Can't fake that. Unless you have a swapped engine.

 

Here are more pictures of the motorcycle.

 

I'll check that out right now, thanks.

 

It all depends on what you want to do with bike , Restore/Customize or part out , Best thing to do is take piece of paper write out parts that will be required and figure from there , most of us put between 6 and 8 hundred $ into bike. This would be battery, Brake pads/Shoes , new brake hoses , fork seals , tires , carb overhaul , clutch , and misc items . Since your bike appears to be missing tank/seat/side covers/front disk/caliper most electrical items/coils , your would be shopping for these items on eBay or a salvage yard ...it can be done but it depends on your budget.

 

I do have two sets of brake shoes and pads, the tank, and seat. The clutch is still in a good condition and it does shift through the gears. But I do agree. It would just come down to the size of how much I'm willing to put into it to get it running. Thats why I was wondering about all of the electrical components thatI am missing just to get it going. As far as the carbs, I found a set, just for the wrong bike now that I know its a Seca 750.

 

Very obvious it is a 750 seca. Or maybe I should say it's very obvious it WAS a 750 seca.

It would be easier to make a list of what IS there. Then what's missing is everything else.

 

If you've got good tennis shoes, a pillow for your bum and you’re at the top of a hill, that bike looks perfectly capable of getting you to the bottom!

Not so sure you’ll stop when you get there, though.

 

Thats right not sure how far I'll make it down, but I will make it to the bottom somehow.

 

the XJ550 is also a DOHC
with it being a seca 750 you will have more used parts available to you then if it were an XJ650RJ.

 

I was read an article in a bike magazine , guy built a bike with just the engine and bought ,traded for the rest , you could always take it all apart , clean and paint and reassemble take your time and have a restored bike . You could be like me buy an 850$ seca dump a bunch of money into it and it is worth 1200$ BUT I once bought an 82 Virago for 400$ put about 300 in it and sold it for 1500$ , another time bought an 81 Honda CB 750 custom for 1100$ dumped 300 into it and sold it for 2000$ granted both of these bikes were truly low mileage strange but both had 4500 miles and for the most part mint .

 

So far I have found the regulator, the igniter/CDI box, and the ignition coils just to get started. Would these be the main things to just try to get the the motor to turn over?

 

That's sort of the situation I'm in. I only paid $200 for the bike in total, but I also did not know that he had stripped this much off of it. I also am not too sure of how to take apart the engine from the frame or what I would need to do that in order to check the engines seals. But if I could put in less than $600 and one day sell it for $1000 that would still be a profit. This is why I'm trying to get a list of what it would need to get it running and then try to go from there. And this group of people have really helped out A TON. I'd love to really restore this bike, so I may just take my time with it and take it slow.

 

Are you buying for pleasure or to make money? If you think this s going to make you money you are in for a shock.
If you want to use it as a learning ladder then it might be a way to learn, might even be cheap, but I wouldn't bank on it.

 

check your valve shims for spec this is how
Bigfitz's AIRHEAD VALVE ADJUSTMENT with Pics - parts I & II

get a battery and do a compresion test to evaluate motor if motor checks out, clean the carbs if the motor runs than consider what you want to do with bike.

I attached the minimum wiring diagram with that you can at least wire motor to start

 

I planned on using it as a learner and for pleasure later on since I'm just getting into the whole building process in itself.

 

if you are in it to make money a running motor is worth more than you paid for the bike and a cleaned wet set set of carbs is too.

 

Yep... @Minimutly is spot-on. Fixing up a bike up from the condition yours is in... will be a labor of love. Never a money-maker (on almost any old vehicle). The electrical bits and bobbles you need can quickly reach several hundred bucks. Not to mention the seat, carbs and airbox.

I'm slowly fixing up an almost complete bike as a 'learning experience' side-hobby, and the refurb is over $3k at this moment.

 

I have checked ebay and have found a set of carbs for around $120 at the least.I just don't want to have high hopes and then a major set back happen. But, that's what comes with a project.

 

Yeah @turpentyne ive began adding up just the minimal things to get it running and right now I'm at around $135 in electrical parts

 

the cluster you have a photo for is for 550 650 and 83 750 maxim not a seca

 

Yeah I'm not quite sure what happened with this bike or how it got this mixed up. For now, I just have to work with what I have I presume.

 

motor first with carbs then if good, start planning your build.
do the free stuff checking wiring cleaning connectors

 

Awesome. Thank you for the advice. Get it running and then go from there. As for the wiring, to get it running I would need to purchase the coils, a CDI, and a regulator, correct? Would it turn over without having the relays?

 

Or, just build and don't count $.

I'm building a couple MaximX's from scratch and parts......one is where every part is either new, refinished, or detailed. Another one is simply putting the right parts on, as long as they are in decent condition, and some mods are allowed for that one.i have two or three other X frames to build at some point, too. Here's when one started when it arrived in the mail last week.


It's only missing a few more parts than yours....

Dave

 

This one is going to have a virago 1100 front end on it. (actually, it already does.....I rolled it outside this afternoon so i can work on some other stuff)

 

yeah it is But it is a good looking frame.

 

The way I am looking at it now is if I can have it running on cheap pars that will work for the time being, I can go back and buy new replacement parts. Or my better option would be just to go ahead and buy all new or refurbished parts. I just want to have it running in order to make my decision because it will all depend on the condition of the engine and clutch system, my major moving parts. Worst comes to worst, I could always just sell it for its parts or scrap it down and start from scratch.
