As a follow-up to that last post, the ultimaker s5 was the only printer I could find with a big enough bay. There may be others - you will need a...
Hi everyone. I recently started a project with another community member to make a 3D-printable side panel for the xj650 maxim (1982). I got a...
Hi everyone. A little update on my project with @Dan Gardner 's righthand panel. I got a basic 3D print file made and was able to print and test...
Yes, this would be very helpful. I'm going to try with an xj650 right panel. The critical measurements would be the distances and angles between...
Saw this thread while looking for a xj650 right side cover CAD file. Anyone good with Solidworks/AutoCAD tried to design it yet? It would be...
Hello, i’ve got a 1982 xj650. Spent the past year fixing it up and it seems to be working quite well now. One thing I’ve noticed is when the...
I guess my post had the wrong tone, but yes that’s what I plan to do. I didn’t do the bench sync right and I certainly suffered for it. Lesson...
Now im just worried about the electrical system. Really hope its not related and an easy fix but the coincidence is odd (broke within a half hour...
Wow! It works! Or it worked for like a half hour until the electrics cut out (hopefully an entirely separate and non-related issue). I did the...
Okay I’m setting the butterflies to just cover the front edge of that progression hole on all carbs so that the hole is NOT visible. Then I back...
Ok, thank you! Just to be clear, after getting the rack off the bike I individually tune each carb (starting at 3, and then moving outwards doing...
Tomorrow I’m going to take the carbs off and try to line them up exactly as you have said. I know they’re all very similarly angled and close...
Yeah but I dont think pods are enough to cause a 7k idle.
@NikoRx little progress, no electrical issues. Taping up the pod filters reduced the idle rpm to like 4-5k but not a solution. What is the...
did you ever figure out this problem newguy? Having the same issue now; ive tried everything and cant figure it out for the life of me. Idles at...
hey it looks like this thread has been dead a while. Anyone figure out the issue to michael’s problem? Having the same issue right now and I cant...
It’s worse today than it was yesterday. It either doesnt catch or I use starter fluid and it goes crazy. Yesterday the high rpm’s were at 3.5k,...
Is the standard fuel mixture position 2.5 revolutions out from seated for the xj bikes? Ive heard 2.5 as standard for most bikes and I’ve been...
I have not tried messing with the idle screw. I think it’s all the way out, so barely any air is getting in. I’ll try that but wouldnt opening the...
Ok so after doing the wet set, throttle shaft seal replacement and subsequent bench sync, the bike is better but still has issues. When i can...
could you elaborate on where you put the cards? Are they feeling drag from the movement of butterfly valves?
Update: this weekend I replaced my throttle shaft seals and fuel rail o-rings, then bench synced and did a wet set. Got my float heights to spec...
How much should a change in fuel level in the carbs affect performance? I did a wet set on carbs 1 and 4 today and both were about 5-6 mm below...
The pdf writeup said to get loctite and anti-sieze fluid for this job. I know the loctite is for the self locking screws, is the anti-seize fluid...
Ok im in the process of taking apart my carbs and replacing throttle shaft seals and fuel rail o-rings. The butterfly valve screws (holding the...
My fault, should've started with for an '82 xj650 maxim. The carb for that one is a hitachi HSC32
@Jetfixer does anyone know the correct size for the fuel rail o-rings?
Going to do a throttle valve seal replacement, bench sync, wet set/check bowl heights, and then see what that does. Anyone know what the proper...
Bought the x-profile O-ring that polock suggested. Did you mean to use these in replacament of the actual throttle shaft seals or as the correct...
Planning on doing this job on bike soon. Just to be clear, I should replace the O-rings AND throttle shaft seals? Those are two separate things?...
So I took a look at the spark plugs to inspect them and they’re super dark, like theyve been carbon fouled. How can that happen with a lean...
Ok, thanks. I'll do it again. I already did a bench sync but I'm definitely going to replace throttle shaft seals and set the fuel levels. Thanks...
I could see a nonconventional kickstart that is kicked forward. Sitting on the bike, shoving the foot forward almost seems like you might get more...
Had the same issue as you. The three things required for your engine to run are spark, pressure, and fuel/air mixture. When this happened to my...
I'm not but I wonder how his project is going. Do you know his name/link to the post? I might get a good lead from him As of now, no. Not sure...
Hello, I got this bike about a year ago. In my other thread I've posted about certain problems it has idling very high but once that's sorted out...
I started a thread and I've been updating it a lot. If you have the time please check it out I'd appreciate any advice.
Thanks, I'll try that. it runs... a little too well. It idles at 8k rpm and I'm trying to root out a cause. I don't think low cylinder pressure...
Anyone have suggestions for a good place to get '82 xj650 maxim compatible shim kits? Also if I plan on only doing this once or twice since I'll...
Are you talking about expected cylinder pressures? I did mine a couple months ago (been having issues with my 1982 xj650, posted a thread about...
Also do you have an airbox or pod filters? stock or aftermarket exhaust? These things can make a significant difference in how the bike runs
I saw the title of your thread and was hoping you had found a solution by now. I'm having the same problems. As of now my xj650 '82 is running but...
Notes for a ~68 degree day: tried lowering the jet needles to see if too much fuel entering the carbs was the issue, but it made no difference....
... correction. I put the original jet needle back in. The needle jet (which to clarify is the cylindrical piece with holes in it that sits in...
Ok, after reading this today I took off the carbs, put the original needle jets back in and bench synced the carbs. I have read the church of...
Hello, I got this bike about a year ago (summer of 2019) and have been working on and off (since I have to be at school during the spring and fall...
