This should be oil-cooled, not water-cooled, I think. So no fan... While it's possible that the new clutch itself is having issues, I agree with...
As XJ550H mentioned, and you said in your first post, you really should start with the valve clearances. Assuming these are out of spec, when you...
Tigard!
Well, I have verified that all the oil control rings are good and offset correctly. I have a gasket set on the way (Thanks Len!) and am planning...
Hey XJ550H, appreciate the help, but... Did you read the whole post and what I was asking about? I'm mainly trying to figure out if cyl #3 is...
Hello XJ community, It's been a while since I've posted here. I have a 1982 XJ650 (with a non-YICS 1980 engine from a PO's swap) that I've been...
Certainly. I will try to get some pictures. Going off memory, though - in the float bowl, center, taller tube = copper washer and main jet...
What I mean is, if I know the plug is fouled at ~30 miles (which should negatively affect fuel economy), so I swap plugs every 15 miles...
Well... Went for several rides over the long weekend, and even changing the plug on cyl 3 every 15-20 miles with a spare clean plug I'm still...
OK well I have a little more news to report. I swapped needles, got it all tuned and synced and it was idling perfectly at 1100 RPM. Had time to...
Yes, I checked this earlier this year before I decided to rebuild the top end. This is great info, and your pre-needle-swap description seems to...
Thanks Dave, I assume you mean the large hole that the slide needle moves through up top (in the carb throat) vs. the tiny holes in the tube...
Thanks for the responses. The reason for going one size up on the pilot and main fuel jets were based on Len's suggestion, I had at least one...
Let me start off with a quick description and a list of all the things I've done: My XJ650 seems to get ~25MPG under all circumstances. Riding...
I keep forgetting to post back here, but I ordered the Yamaha OEM exhaust gaskets from Len (instead of the aftermarket ones that came with my...
I love the attention to detail and ability of enthusiasts to be able to successfully pull off a repair like this - that saves an otherwise good...
Your best bet is to order them from xj4ever. PM user @chacal or click the link in the top right of every forum page for his catalog. He can get...
After a few weeks of having the bike apart, finally got it all reassembled and fired up. Despite not having tuned or synced the carbs, I took it...
Yes. Please read this beautiful novel in its entirety: https://www.xjbikes.com/forums/threads/in-the-church-of-clean.14692/ This is everything...
First thing I'd do is check for vacuum leaks - you can use an unlit propane torch on low and waft it around the intake boots, airbox boots, and...
Yeah basically put a straight edge of some sort across the top of the studs and measure from the bottom of that down to the port opening, where...
Well I had my friend (who works on large compressors and vacuum pump systems and has plenty of automotive/motorcycle experience) come and...
Hmm well I will give it another hard look tonight, and I have a friend coming over who will give me a second opinion on it... Seems that either...
Agree with above; should cause no issues. I have the 90* filter and there is always some air trapped at the top of the filter, but you can see...
Great, thanks for the confirmation! No, studs are the same as before the rebuild, and were never removed.
See that is what I thought at first, and I looked at this thread:...
I have the exhaust separated into halves right now - and had tried mounting up one side. I had no issues getting the header pipes up to the...
Yesterday I started reassembly of the top end of my motor. Everything went fairly well, except of course I need a couple of valve shims I don't...
I believe this is the info you're looking for... https://www.xjcd.org/node/664 Should also be in your manual if you have one.
I got both the bulbs and the flasher unit from superbrightleds.com. I've been a customer of theirs for many years and always found their products...
How does it run? If compression is even across all four cylinders, then you can still tune and ride it. Just have to decide if the fuel economy,...
No post for two days!? I guess I'd better post again. Last night I reinstalled cams on my head (not installed on bike) to check valve...
Picked up cylinders and head from machine shop. Cylinders are bored out to .5mm over, honed, and checked for flatness (good). Head has freshly...
Sorry to hear it, that sucks. I'm glad the damage to you (or your bike) wasn't worse. How long will the hand take to heal? Is it just splinted?...
Just carb cleaner and a nylon brush, and some elbow grease... The center screw on the removable rear baffle was super corroded for some reason,...
I sorta wanted to fry an egg in the center of it just to prove to myself that it's "clean enough to eat off"... but then I'd have to just clean...
Dropped off pistons and valve stem seals at the machine shop yesterday. They'll be getting my cylinders bored out to match the 63.50mm pistons...
Fastest turnaround time ever. Also, orders are always accurate, impressive since products aren't individually barcoded. And as always, Len...
I don't have room for a second motor in my garage, and I'm afraid that I'll get one with sub-par compression and still have to go through an...
Yesterday I removed the carbs, exhaust, cams, head, and cylinder jugs and inspected everything. Measured what I could with digital calipers, but...
I swapped in a Hella euro-spec headlight assembly which converts from sealed beam over to a modular lens/bulb assembly several years ago and am...
Did a 40 mile ride on a country highway today and had no issues with the turn signals, aside from canceling them myself each time. Used them at...
Alright, I was able to ride home on my lunch so I could lift the tank and unplug the auto-cancellation unit... voila! Works perfectly, only...
Was able to get front and rear wheels removed and down to the corner tire shop and get some new rubber on the bike yesterday. Tires were VERY old...
My sincere condolences... I can't even imagine losing my wife. Hope the healing comes easy, once it's time to do so. Until then, enjoy that...
Hey guys, Having an issue with the turn signals. They work great at idle, but when I'm riding I can't get them to come on reliably. Like maybe...
Earlier this week ripped the carbs back off and cleaned them very very well, focusing on the pilot circuit but also checking everything in the...
Dang! I looked in the catalog for it, and didn't see it... but should have asked you. I don't think you've ever told me you didn't have a...
I saw that when I googled the company as well. Seems like an odd business to be reselling Colortune kits. Or, maybe it's just miscategorized....
I wonder how you were able to get a good seal to even be able to dial in the mixture properly? The washer I used (and got a good seal with) were...
