Recent acquisition

I just recently acquired a 1982 xj750j
Here is a picture with the tank and seat removed. My plans are to chop it, hard tail it, and bob it a little. It's going to be a mix rat/bobber type thing. Should be awesome when done. Acquired this bike for a bag of fertilizer, sat next to his garage for a number of years, cleaned the carbs and it fired right up very strong runner.

 

Nice score! But it is a 650 Maxim.At least the pipes,forks,grabrail,exhaust hangers and taillight are.But I wouldn't complain,for a bag of fertilizer! Tell the guy you got it from that I have a chicken that I would trade even up for an R-1! Great deal,and welcome to the site!

 

The side cover says it's a 650 but the insurance card in it says xj750j.... so i dunno?

 

It appears to be an XJ650, it has the 650 style gauges and only a single disc brake, that means it's either an XJ550 Maxim (chain drive) or an XJ650 (shaft drive).

Here's the VIN breakdown for the bikes. These 3-character codes are printed on the decal on the LEFT side of the steering neck, stamped into the steering neck on the RIGHT side, and also appear on the right rear of the engine case on a flat machined pad, just behind the clutch cover. Of course, it will also be on the title, as part of the entire VIN number, but will be preceded by the manufacturer ID Code (JYA), so the first part of the title VIN will read "JYAxxx" where "xxx" is one of the codes below:

XJ550 Maxim:

1981- 83: 5K5 (usa) or 5K6 (canada)


XJ650 Maxim:

1982-83 5N8 (usa) or 5N9 (canada)


XJ750 Maxim:

1982: 15R (usa) or 15T (canada)
1983: 22R (usa)

 

Grab rail isn't right for a 550.

550 has slash tip exhausts.

I think I can make out the pinion housing.

Verdict: 650

 

I may be interested in the seat. PM me if you still have it.

 

My paperwork had the serial number and "750 Maximum" I checked the numbers and everything and it turns out that its a 650 Maxim. Loved the deal I got from the guy who had no clue, wasn't too happy with the work needed to undo aforementioned guy's cluelessness. I thought about hard-tailing mine as well, but I am going to leave it stock-ish. I am going to chop my Suzuki once I get my hands on a garage that's not over an hour's drive away

 

I'm going to check the numbers when i get to the shop tomorrow. i'm doing all of this where I work so it will make it real easy. I will also post progress pics and anything from the bike for sale. As of right now I have a stock air box, the seat (pm sent), Rear fender, grab bar, and sissy bar, looks to be stock handle bars. i'm also thinking of ditching the stock cluster pod and all of the controls... still up in the air about that.

 

Pm'ed you about the sissy-bar.

 

Also the tail lamp, and all turn signals are for sale as well. and the front fender. Anyon know where I can find out or how I can do a dual front disc? And know of any other gas tanks that will fit? Also i'm looking for a 4-1 exhaust head pipes and collector, don't need the muffler or anything after the collector.

 

I believe a 750 XJ tank with fit the 650's with no problem. Also, if your bike has a single brake in front its probably a 650, in which case you can change it out with the 750 front assembly, but you'll also need the master cylinder. I believe this is the case, but don't take it as gospel.

 

Marko is exactly correct in his recommendations, although I'd add that the front end assembly needs to be off of a 750 Maxim, NOT a 750 Seca!

 

Woohoo!!! See, I'm learning.
750 Tanks are in heavy competition, being that both guys with 750's and guys with 650's want them, so if you find one that's a good deal I'd jump on 'er p.d.q.

 

turns out it is an 82 xj650 maxim

after day 1 of build

 

WOW, I forgot how hideous stock maxim bars are 8O . Glad to see you chopping it. Keep us posted. I haven't been able to get mine in the garage yet. Two rhinos, my cbr, a golf cart, a bridgeport mill, lathe, drill press, saw, plus various cabinets, work benches, and toolboxes kind of "clutter" the work area.

 

The stock bars are getting trashed for some drag bars should be arriving any day now...

The ones that arrived were wrong so i made some.

 

Update on things. I had a little time to mess with it. Got my drag bars put on, oil change, and stuff set up now it's tore apart and ready for paint.

 

What do you guys think of what i've done so far?

 

Looks good. What material is the seat? Are going to stick with stock wheels or switch over to the spoked ones in the background? BTW, is that a 750 in the background? The only thing I don't like about my XJ is the lack of kickstart haha. But yeah, enough with the questions. Looking good!

 

That seat is vinyl, i'm going to put on a spring white leather seat. Keeping the stock wheels and painting them. In the background is a '76 kz400. Guy at work got an itch after he saw mine... thats the next chop. I don't like the fact there is no kickstart and its shaft drive... but for what i gave for it and what i have invested i won't complain.
