XJ750 maxim parts compatibility

Hey guys and gals, I'm completely new to bikes. Couple weeks ago I picked up a 83 XJ750 maxim. Needs a good amount of things like wheels, rotors, calipers, forks, handle bars, gauges and headlight haha. Also brake pedal and shifter. I was wondering if the 83 seca 750 parts were compatible. Thank you i n advance.

 

Many of the parts are the same. You can look up what parts swap here: http://www.yamahapartsnation.com/oemparts/#/l/yam/5004238df8700209bc787a94/1983-xj750k-parts

Just find the part, click the part number, and a list will open with all the models that part was used on.
For replacement parts start a conversation with Chacal (though major components will be an E-bay thing or the wanted section here).

 

Thank you

 

While there will be some interchange. The Maxim is different enough to cause problems trying to mix and match parts with a Seca.
Wheels, and rotors will interchange but the Seca used an 18" rear wheel. The Maxim used a 16"

calipers, forks, handle bars, and headlight : Only as a complete assembly (triple tree, forks. calipers, bars, light) The anti-dive forks, and modular handle bars on the Seca limit compatibility.

gauges: NO! The Seca used an electronic (Atari) gauge cluster that is not compatible with the 83 750 Maxim wiring harness. The extra wiring for the electronics is not in the 83 Maxim harness.

Sounds like you got a parted out basket case, and need to build the bike from the frame up. Your in for an education and will get well acquainted with the parts schematics. I use Babbitts: http://www.babbittsonline.com/partsdepartment, or Partzilla: http://www.partzilla.com/

Post some pics of what you have, and some ideas of what you would like. There are many here that can help suggest what parts will help get you there.

The 750 Seca has normal round bars under the foam covers.

 

I stand corrected!

 

No need to stand. Have a seat; relax.

 

Actually, they don't-- the 750 Seca has round bars, but there are little Stand-offs and hooks for the control wires and cables. The covers are not foam. They are a two-piece plastic cover that bolts together and sandwiches the handlebars inside. The bolts go through the stand-offs.....

 

The covers from mine are expanded polystyrene foam. The moulding process gives them a soild outer casing. But yes, the bars are a bit special....and round...and 7/8"...and

 

Interesting... Mine are all hard shell plastic

 

Hmm... I think we're talking about the same thing but thinking it's different, or I'm thinking of a different thaing that is not the same. Now I'll have to go dig through my parts stash.

 

Mine are a somewhat flexible, vinyl type plastic.

On the left bar, you can see one of the tabs (stand offs?) sticking out of the cover's seam.

 

That's what I got

 

Thanks for the info guys! This is the best picture I have at the moment. Haven't been able to work on it due to work but hope to start soon. Bought the bike to learn how to work on them and then learn to ride once I fix it.

 

Holy crap..... You've got your work cut out for you!!!!!

 

First things First!!
You need to have that frame checked! That was a pretty severe wreck to twist those forks, and break that wheel loose.
I would hold off on gathering parts until you know for certain that the frame is straight, and safe to use.
Broken welds, and possible bent frame will be an absolute nightmare to deal with for a first bike.

Just my opinion. That would be a good parts bike for one in better starting condition.

 

Looks like the bike came to a sudden stop against an immovable object!!
I agree a better donor than rebuild.

 

That's kind of what I was alluding to---

To be specific, looks like a wreck:

Broken forks, never saw a rim bent like that before..., scraped engine fins and engine side cover, rear brake lever scrape on oil cover, boogered rear turn signal, all the other front end damage, tank damage....

Then general stuff:

wiring nightmare
Pods
Missing parts-numerous

 

Yeah got it for $100 dollars lol so I thought why not. As far as I can tell the frame doesn't look bent and no broken welds. Most of the damage is in the front end. I might be able to work in it today so I'll post more better pics

 

it may not look bent, but it took a hit hard enough to bend the left fork to nearly a 45 degree angle, break the axle right out of the right fork, turn the rim, inside out...... I'd bet there's no way that frame isn't compromised.

The MOST intelligent thing to do RIGHT NOW, is to say "cool... I just got a $100 parts bike----now I can find a good 750 maxim to build, using a lot of these parts".

Yes, I understand emanating to build your first bike, the excitement of finding this, but be realistic. If you try to build this one, you're gonna be discouraged very quickly.

If you're new to bikes, you NEED TO UNDERSTAND THAT JUST BECAUSE
IT LOOKS STRAIGHT AND UNDAMAGED DOESNT MEAN IT ISNT. It can Look good but be totally bent. If it truly isn't, you're darn lucky.

Next question--- is the title still clear?!?!

Usually we buy a decent bike to restore, then look for parts bikes to pull parts from. Right now, you're just doing those two steps in reverse order.......

 

Yeah I get what you mean, I'm already discouraged as it is. Haven't found any other bikes out there to use for parts or build. Closest I found is a 83 seca 750. The guy told me to take it for 200. Its complete. Haven't asked what's wrong with it since I have nowhere to store it. I'll probably end up junking the bike and taking that $100 dollar loss. https://ventura.craigslist.org/mpo/5679620929.html link to the seca

 

Also the title is clear

 

There is no reason for you to take a loss on that bike. If you send the bike to a junk yard. You are basically just giving the junk yard free money. They will part the bike out and take the money you could have made.

You could part it out and make your money back plus some extra to put towards another bike. There are guys that do just that to fund their bike projects.
Check the sale section for guys looking for parts that you might have. You will also learn how the bike is put together in the process.

I can see several parts that I would be interested in getting if you part it out.
wiring harness, side cover, foot peg assemblies, etc..

Limited for space. Set a time limit. to sell off what you can in that time. Junk the parts that are damaged beyond use, or obviously not going to sell like the wheels.

Right now you're not out any money.... You own all the parts. You can part it out and get your money back, and probably make some extra.

That 750 Seca isn't much different..... There's enough parts there to make some money, but it's a real rough starting point to try to build that one, too.

But if you do part it, don't expect the money to just pour in... You'd have to sell parts as they go, or as people ask for parts. This means that you have to be able to store the parts somewhere in the meantime.

I highly recommend that you look for a much better bike to start with, and a good place to start is to ask right here in the forums. You'd be off to a much better start.

I'm sending a private conversation to you, too. Check your inbox.

Funny--- that's what I told him in the pm, too.

 

Yeah you're right I'll part it out while I can and see if anyone needs anythjng. I got to excited when I bought the bike and wasn't really thinking. Had a lot of free time when I got it and I've wanted a bike for so long so I thought this would be a fun build. Then I got more hours at work my friend (i store the bike at his house) got a night shift. So yeah this didn't turn out si good haha. Thank you very much to all of you though for all your advice and honest opinions. Went at this blind but you all helped me see the light lol much appreciated.

 

Just trying to help you get started on the right foot.
Been There, Done That. It is still my Nemesis! Over $1K invested and it is still a bare frame 10 years later.

I'll send you a list of what parts I am interested in.
Then we can work out a price.

Get some good pics of the exhaust. I might be able to use some of it on a project that I am working on.

Hope you got $$because your going to be nickel and dimed to death,, except in the $20.00 category. I got parts, eng.etc.

 

OP hasn’t been seen since Aug 2, 2016. I doubt he read your post.
