Thanks xHondaHack, someone before me relocated the ignition cylinder and it appears tried their hand at some "custom wiring" to the fan (which...
Found the wiring diagram. A bad connection looks to have caused the issue. Brown wire going to thermoswitch now has voltage. To test the fan,...
So after getting the charging system operational again, I got the battery box, battery and wires all neatly back in place. Let the bike run to get...
I also want to look into the fan switch upgrade that turns it on sooner.
Have any '5-Valve' carb covers or factory airboxes?
XJ550H provided a cross reference link for me when I was looking for coil replacements for my X. I ended up purchasing a few used ones in good...
Victory! After disassembly, cleaning, wiring repair, testing and reassembly, I having a working charging system on Max. The bike has been...
Had to swap coils recently on my X and it was time consuming, but I got all cylinders to "light". Good luck with the upgrade. Curious, was finding...
Good info hogfiddles, I knew, visually on the bike, they looked similar, but being that the air head and 'X' use different carbs, it makes sense...
Another part I've found that's hard to find, the factory airbox. Luckily I have one, but I occasionally keep an eye out. Maybe someone can...
Field coil cleaned and tested good at 3.9 - 4.0 Ohms, however while looking at the wires going to the battery, I found a brown wire attached to...
It certainly did, it even provided the way for me to test the diodes in the original rectifier....which tested good. Hopefully the fix is either a...
Great information 866, the testing procedures and specs were very helpful. So I removed the wire extension someone added to the stator coil, cut...
Now that I got the carbs reinstalled and the engine running, I m trying to tackle the non-charging issue. I swapped out the rectifier, hoping for...
Simmy is right, the 'X' was produced in 1985 & 1986. They were arguably the quickest of all Maxims. Its 5-valve engine is a cool piece of history...
Got any pics of your XJ750J with the Maxim X grab bars? I'm curious how that looks.
Thanks for the compliments, mine didn't have original paint left, so it made the decision easy to paint it the color I liked.
Thanks, still have a ways to go but it was a nice day for a picture. (it's come a long way in a short time)
It's alive! After many hours of troubleshooting, rebuilding plug caps, replacing coils and addressing the carbs, the X fired up today and ran on...
Thanks 866, I bought the bike earlier this year and someone had spray-bombed a lot of it black at some point. It left a lot to be desired...the...
Just a progress pic. Reinstalled the painted rear fender with new brake light and blinkers added, I two-toned the side grab bars to highlight the...
I'm not a big fan of the generic designs but, in my opinion, the K&N or DNA oval filters (when clean) look good. I have considered velocity...
Figured, while the coils and bracket were out of the way, I'd take the valve cover off, spray it and polish the hold-down bolts. Also took the...
866, speaking of sensitive carbs, are you running the oem airbox? Mine came with cheap pods, so I'll probably take the box off my parts bike and...
Thanks 866, I'll keep that in mind. I kept the old needles and seats in case I ran into an issue. I used a caliper to measure the new seat and the...
Thanks for the info. I didn't see any ground wires, only the bracket which held both coils and horns. So the carbs have been cleaned and rebuilt....
Question: Does the ignition coil bracket on XJ700Xs act as a ground in any way? (I noticed the bracket's removeable and bolted to tabs on the...
Ordered a set of used ignition coils that are compatible for my bike and test well. While they were being shipped, I spent some time painting the...
Good info, thanks. K, do you have a recommendation where to find a new performance clutch set for these transmissions?
Question: Do the XJ700 & XJ700X use the same transmission?
Thx. -Message sent
Any update on air box and boots? Also, how do the intake boots look? Thanks
While I was in the area, I thought I'd knock out an easy job. I took the faux fins off each side of the engine to clean them up. They were...
Took the caps off and exposed good wire on all four and tried again....no reading thru the wires but 2.7-2.8 ohms at the connectors. I have a hard...
Are the air box and boots in good shape?
Nice work!
Good comparison Simmy, so I guess I better hang on to these carbs then huh? Questions: With 911cc displacement, did the BS33s still work well for...
One reason I'm glad I have a spare set carbs for my X. Can't imagine how difficult or expensive it might be to buy another set. Although I wonder...
Glad to help!
Update: Testing from wire to wire, my multimeter gets no reading, however testing at the connectors, I get 2.8 Ohms on both ignition coils. I'm...
I get nothing for the primary side test on either coil. Looks like open circuit. Going to clean connectors and try again.
Have you measured the inner diameter on the throttle blade side. I believe the "33" in BS-33 means the size in millimeters. Mine measured 32.99mm...
I have an '86 XJ700X that I'm currently working on cleaning/rebuilding the carbs now. Your carbs look very similar to mine (which my literature...
Great stuff and now I don't have to search other threads to get a link. Thanks New question, I pulled my ignition coils off (one soldered wire...
Great link 550. I'm installing new needle and seats today, leaving only the floats left to pin in and set. Then, it'll be on to bench synch.
Looking for float level height on this 'X', and where the reference point is to measure from.
Well, disassembly and cleaning is basically done. Now I'm waiting on a set of new main jets and O-ring silicone grease to come in the mail. I'm...
Ok, mine is an '86. The pilot air jets are stamped 140 and the pilot fuel jets are all 35s. Question, should these pilot fuel jets have rubber...
Yep, not one main fuel jet to be found! Pilot jets were there, but each was clogged completely. These XJ700X use #105 main jets, correct?...
Took my carbs off this weekend and started disassembly. Was pleased to find that the intake boots were fairly pliable. Since my bike didn't have...
