So I’ve been playing with my carbs, they’ve always been a bit “sticky”, and frankly? I’m tired of it. They’re just the standard USDM BS34s (“Bit Sticky”?)… I’m broke and I’m cheap, but I don’t mind spending money on performance if it’s worth it. What should I do? Buy new diaphragms? New slides...

It’s that time of the year again! Yep - my dumb ass needs a new battery. Does anyone know the model number for a 1980 XS650 Special battery? Preferably just like a standard Yuasa? Thanks!

So I got two short blocks (plus heads, jugs, etc) when I bought my Special, and it’s always been my intention to just “maintain” the engine that’s currently in my bike, and do a complete teardown and rebuild with one of my spares. That way I can eventually have a nice solid mill, good...

Alright I need to do something. This 2-into-1 turnout I have sounds like absolute s***, and either the baffle is completely rotted, or it never had one to start with. Either way it’s not a serviceable part, so it’s junk. I’m thinking of going back to stock headers (Anyone got a relatively-clean...

I’m looking for some stock reasonably-priced headers for a 1980 XS650 Special. They don’t have to be show quality, but no dents/dings/rot/etc. Just the headers.

So I finally got around to rebuilding my forks - 1980 XS650 Special - and I was wondering how much fork oil I need, what type, what torques for various things, etc?

So I got my shifter more or less figured out, I replaced my clutch cable, I’ve got the bike on the centerstand, going through gears, I pull the clutch lever and... Nothing. Nothing at all. I’ve tried adjusting it, it’s pretty flaccid in general, and I think the cable is jumping off the lever...

Sorry it’s been a while, I’ve been mad busy with work, so I haven’t had any time to work on the XS... So here’s what’s up: I replaced my shift shaft last fall - if you’d believe it, the SPLINES actually rounded off on the shaft, rather than the shifter wearing out - and to make a long story...

Hey guys. Last fall I replaced the shift shaft on my XS, it went through the gears just fine, the bike sat all winter... I thought maybe it was nice enough to ride today, and now it won’t go into second. For what it’s worth, I also removed my kicker, since the tab for the spring on the engine...

So I’ve got a 1980 XS650 Special, couple miles on it... To make a long story short, the splines on the shift shaft rounded off a bit, and it won’t go into gear, the shifter rotates on the shaft with both shifters. I tried replacing the toe shifter, that’s not the problem. I know it’s weird for...

So I’ve been having some carb trouble - I think I’ve finally got it sorted out, ridiculously high idle, replaced the diaphragms/slides - and I took my carbs apart yesterday... You know that rubber piece that goes in under the pilot jet? Well after I drained my carb, it was all swollen. Why is...

So I’m rebuilding/upgrading the forks on my 1980 XS650 Special, and I just can’t get that Allen bolt on the bottom out! It rotates freely, but it just won’t come out! It doesn’t even look like it’s moved! Both forks are like this! Now it’s been a minute since I rebuilt a pair of forks, but am I...

Hey guys, so I have a 1980 XS650 Special, single front disc, and I installed an Emgo superbike bar on it. Now, the stock front master cylinder reservoir looks like it sits kinda “funny” because of the radically different bar. I was wondering if that seems to be a common issue with my model, and...

Hey, new guy here! I’m Max, I’ve always wanted an XS, and well, a couple weeks ago, I finally got one! 1980 XS650 barn find with a literal truckload of spares! So I was rebuilding my carbs, and I found a stray light green wire by my backbone... My headlight is out, and I looked it up, LG...
