Howdy fellas... Anybody out there own an early YamahaFZ?
I've got an '86 FZ600 (with just 16,000mi.!), and it's an excellent first ride, although it wants much more abuse than I'm capable of dishing out- hope to get it to a track one of these days, just to see how far I can push my luck!

Haven't found more than an occasional mention of this bike elsewhere on the net (or anywhere else), so I thought I'd toss a line in here. I'd be interested in hearing from fellow FZ/FJ/XJ600 owners who'd like to know of each other's existence, for those times when questions like "How the F**K do I get this **&*&U#$# valve-cover out of the frame without taking the whole damn engine out?!" or, "Doesn't somebody make a spin-on oil filter so I don't have to remove the whole freakin' exhaust in the dirt in front of my apartment?" can't be answered by your local dealer. Where to get parts, any useful mods, etc. (Can I fit an EXUP exhaust? Does anybody make luggage that fits?)

BTW, having plowed through all the '86 magazine articles on the subject, I gather that the FZ600 was viewed at the time as the "real" original mass-racer, as it's certainly got a helluva lot less fluff than Honda's VF series, and killed everything else at the track.

Cool Welcome, chmccand...

I used to race an FZ600, back in '87. Unfortunately, that was the year that the Honda CBR600 Hurricane came out, and it totally outclassed the FZ. So the FZ was only dominant that one year, 1986.

On the other hand, despite having to battle with the faster Hurricanes all year, I was able to win two class championships, and the P.R.R.O. (Phoenix) #1 plate in 1987 on that bike, so I'll always have an affinity for it.

It's been a while since I worked on an FZ600, but to answer a few questions: Yes, you can get the valve cover off with the engine in the frame. I can't remember the trick to it, but I know it can be done. As far as I know, there's no spin-on oil filter application for those older engines. And I've never heard of anyone installing an EXUP on the FZ. If you want to try, get hold of a service manual and parts fiche for a bike that has EXUP, and see if it looks like it could be done. Prepare for some pretty major fabricating, though...

That's a sweet looking bike there Scott. I remember it being one of the first bikes that gave me the bug.

Thumbs up Thanks Scott,

for the reply and photo. Nice bike... still have it?

I've gotten the valve cover off once before- it's like one of those barroom ring-puzzles, though. I should just yank all the wires out, which makes it much easier, but the wiring has gotten pretty fragile over the years and I haven't got the time to rewire it at the moment, particularly with a butane soldering iron (no garage to work in.) Anyway, it needs a valve adjustment, and the gasket is pretty trashed (I know it's time to change my jeans when the knees have turned black), and I can't afford the $300 to have it done, so I guess I'll figure it out. I've already replaced the steering-head bearings with conical bearings (what a bitch!), since a previous owner had apparently learned to do wheelies on it, but not to land them ( hope to learn on this machine, too, but I get the idea that it won't do it without dumping the clutch at high RPM, and I haven't found a piece of road I'm comfortable doing that on yet.)

If you think of any bits of FZ wisdom, please pass them on..

Here's another pic (subtract the fairing lowers... it's about half as loud without them... and change the seat to something a little less painful.)

Nah, the FZ is long gone. I do have an untitled frame and swingarm sitting around the shop. I bought it as a spare many moons ago, and I just never got rid of it. If you, or anyone you know, is interested in it, let me know... I'll let it go for a song, just to get it out of my garage.

The problem with these old bikes is that they end up needing so much maintenance, it costs you more to keep the thing running than it's even worth. Hopefully, you'll get some more use from it before it isn't worth spending the money on...

Lightbulb Oh yeah...!

I've got an '86 gas tank (like yours) too. It's got a couple of dents in it (you know how the handlebars hit the tank when the bike is laid down -- like that). But it's fixable...

Thanks for the offer. If I decide to keep the bike longer than this season, I might take you up on that, since my frame (mostly the sub-frame) has some soon-to-be-serious rust on it, particularly around the battery box.

If you have anything else, (or anyone else does) I'd appreciate knowing about it.

Since this is such a hard bike to find parts for, it'd be good to hear from as many people as possible- you might be able to get rid of some of those odd FZ bits and pieces lying around. I know people still race them, so there's gotta be some demand out there. Anybody?

Thumbs up Nitrous!?

Very nice work, FJ6... What size tire goes on that GSXR wheel? Did you have to modify the swingarm to get it to fit? Looks like a real piece you've got there. You must spend a lot of time at the salvage yard ;-}
