My 81 xj550 Maxim build

Got b bar back today

 

When I get it all done I'll have led strips inside it.

 

The plate goes below the print

 

Comments? Too wide, to stupid?

 

I personally like the look of just the bare bar in the first pic. I do see the direction you're going with it and I'm not saying it looks bad or anything.

 

Ok thanks, I guess I think its a bit wide on the top area may be if I would have cut one out of wood or plastic and mounted it I may have tapered the top part more but I just had a guy plasma cut it without a making a prototype first. I wanted to incorporate lights and a license mount and maybe didnt think it though enough. Im in the process of building a cnc plasma and may be when I finish it Ill re do it different. But wanted to get my fender solid so I went ahead and had someone else cut it all out for me. thanks again for your input.

 

I will say it does look like a nice sturdy bar which is a good thing not only for fender reasons but also if you decide to carry any cargo. What's your plans for license plate light? I get what you're doing for the tail/brake. Just curious. Don't think I'm knocking you, you're doing very nice work

 

Ive ordered a small license plate/bolt that you use to hold the plate on but it also has a white led that shines on the plate. Going to paint the hole bar flat black to match the frame. I just ordered 4 8 inch led strips for it. Going to try 2 inside and possibly run one on each side of the bar outside and use the blinker wires also on the outside inside will just be running and brake lights. All that stuff should be here by the end of next week.

 

Looks a bit too Wile E. Coyote for me. Again, that's for me. If you really like it, than I'd consider it well done. It's very quality and you seem to know what you're doing. Not trying to bash what-so-ever. Looks good.

 

something like this would do it


or an octagon with stop in the middle
leds in the octagon and spelling stop

 

I may have to do something else the inside lights may not even be visible enough. I thought about a rebel flag and a Maltese cross.

 

if you go Maltese cross let me know I have a Maltese cross mirror you can have it was mounted through the bolt on the clutch perch on my XJ750j.
or even if you just want it let me know

Iron cross
surfers cross
Maltese cross
all the same

 

your rear fender mount TC bros? just weld it to the swing arm?

 

Yes tc bros mount and I got their cheap fender there also. The mount is only 10 bucks and I cant make one that good

 

thanks for the offer of the mirror. Im running one bar end mirror on my xs650 and I like them I did not realize when I bought them that they came with one for each side. I did not know so I bought 2 of them so I have a extra on hand.
I ordered new handlebars last week and they should come soon.

 

I modified my drawing. I may redo the bar

 

I put the lrd lights in and not happy with it. Back the drawing board.

 

Spent all day Sunday making seat mounts. Welded in a tube from side to side and welded 2 seat bungs for seat springs to sit on. Yup gonna have shocks and springs under my seat. Tonight I mounted my fuel tank. I ordered a high tunnel tank a few weeks ago and it would not work on the bike so I ordered one just like in some of the pictures. Mounted it and it looks good to me. Ill add some pictures later. Ive also decided to not have led lights in the rear. Ill go with something else. Even if I put led bulbs in the sockets but Im just going to have a bar on the back with place to mount the license plate and Ill hang a light above it. I have a pair of marker lights with red lens but the bulb is only a single filament. If I can modify that to accept a dual filament bulb I may try that and have those for running and blinker and brake. I got them I think at a tractor store. made by optronics and part number MC-21RS. My box says I paid 2.99 for them. They look like the newer harley running tail turn lights. Not exactly but appealing to me. And not that being like a harley is important to me. way over priced to me.

 

Put motor in, carbs on, mounted tank, rear lights, bars, exhaust.

Thanks Dadoseven

 

Need some help. Im temporally wiring it up so I can ride it around before the s__w flies. Ive had this running already just can remember what all I hooked up.
I have a question in the pick up coil area. In the schematic it shows black and orange going to one pick up and black and gray going to the other. In the 6 pin connector on the other end of the wires I have only a blue (neutral switch) one black one orange and one gray. So I thought I should have 2 blacks running in to the cover for the pickups. I took the cover off and now Im really confused. I found 1 black 1 orange 1 gray and 1 brown wire. How come I have 4 wires down under the cover and only 3 wires not including the blue one. Did the combine the brown and black wire somewhere and only use the black that I see at the 6 pin connector that plugs into the tci?

 

550 pickups splice 2 the wires together in pickup harness so you have a black(common) gray and orange and blue wire, also in the connector should be a black with white stripe wire not needed to run bike

blue wire does not go into connector or hook to tci

 

That is so good to know. Thank you very much.

 

Got another question on electrical. Can someone help me understand the minimum wiring schematic for xj series that I found on this site.
from the battery through the 20amp main fuse it supplies both the red wire to the R/R and the key switch, through the key switch when turn to the on position does 12v go up to and power a second brown wire going into the R/R or is that brown wire coming out of the R/R then 12v+ and feed the brush and fuse block? Or simply the brown is a regulated 12v to run lighting. Im stumped as to why you would be feeding the R/R with a red and a brown 12v+. any info would be appreciated. thanks

 

i will use the green one

the red wire from the voltage regulator RR charges the battery back through the main fuse. and the bike runs off of the RR when you are riding .

the red and brown are output of the RR

 

when you say use the green one, do you mean the green wire or green schematic? the schematic above is the one I was using.

 

green schematic

 

I do not have a key for the ignition and plan on using a toggle or after market keyed switch. If I use a toggle I would run the red from the battery to one terminal of the toggle and on the out bound side of the toggle attach the brown and blue wire ?
Have you used this schematic before?

 

battery to main fuse, main fuse to switch input ,switch output is blue to tail and lic plate light, brown wire feeds remaining three fuses.
yes

 

thanks again, looks by your signature you have a small heard of these xj's. Got my coils and spark plug caps today in the mail, wires came yesterday. I have to relocate the coils. I bought some chrome 1" spacers today but where I want to mount them they were too tall so I made some from plastic at 9/16" that will work for where Im going to mount them. I have to add new oil clean the chain and probably shorten it. do a temporary wire up job so I can ride it around and Ill finish it over the winter. I have to make a electronic and battery holder box and I don’t want to rush on that. Thanks again for all your knowledge you have shared.

 

Made some progress this weekend, wired it up so it would run without any charging just power to ignition. It ran like crap, hi reving at times my plugs were black on 1 & 2 and wet on 3 & 4 and popping. I thought for sure I was going to have to pull the carbs, more reading led me to adjust the mixture screws on top of the carbs. I ran them down and to the bottom and backed out to 3 no real help so set them at 2 1/2. It was better. This morning I got out my yard stick syncer and adjusted 1 and 2 then 3 and 4 and 2 to 3. ran beautiful. No popping no high idle when you crack the throttle its responsive and idle comes right back down. So happy with the results. Now when I can ride it a bit Ill check plug color. Thanks for all the reading on the site as tuning.

 

hook up the charging system bike will run better 14 volts vs 12 volts or less

 

Just got my electrical connector s yesterday in the mail.
I'll be hooking charging system up in the future. I have to make a box to house all the components in but the r/r which I'll mount on the outside of it. I don't have a good motorcycle battery here to put in it and don't want to make the box till I can design it for a battery. Thinking of one of those small ones made by battery tender. I have a made by me electronic box on my xs650 with a shorai but I'd like to try the tender type.

 

How do you like the shaft drive models of xj?

 

750 is quite heavy compared to the 550 . when you snap the throttle bike hang on tight.

 

Put 1 size larger jets in today. Runs smooth with quick throttle and backs off proper. Plugs were darkening. I may put the previous pilots back in and leave the mains with the 120.
Question seems I dont have a tach and probably wont get one. Does any one know what type of thread is is that I can get a acorn type nut to thread on where the tach threaded on to the motor. Its the only oil leak I got.

 

xj4ever sells blocking plate kit

 

I made one for my xs650. Think I'll pop it out and see what would be involved

 

cant edit and

 

They dont come out that easy. Dont know if it is just an o ring holding it in there but I dont know if you have to do something under the lifter cover to get it out so Im going to wait.

 

remove the hold down bracket ,just the 2 seals hold it in it just pulls out

you may be able to unscrew the adaptor part 5 and find a bolt that size

 

thanks

 

What's the point of a sissy bar if there's nowhere for the sissy to sit?

 

rear fender support. and the looks

 

I needed a seat and thought I'd try making one myself. I had a shop cut me a seat pan but I chose the wrong thickness. I was looking at the web site of where I bought my last seat and he sells pans all cut and bent with the right foam for 25.00 plus shipping. I ordered one. I had never worked with leather before but wanted to try so I ordered some 8-9 oz leather. Lots on the web as to go about doing it so I read up on it. This is my first attempt at this so it's not the greatest but I like it. Here are some pictures of it.

 

Tomorrow after it dries Ill be doing the last thing to it. It putting a water proofing liquid on it and it also gives it a shiny finish. It was a lot of work. I got lots of hours in it.
