Siezed..

Solid.. Note that ithis is the FZ variant engine.. I know but there is No Fz board and the motors are v identical.
Anyhow after a rehabilitation over the dark months (new cam and promary chains and a head job.. the thing was working V well then it decided to eat all it's oil (over a short distance) No there is no evidence if it leaking out.. can only assume it somehow went out the ehaust pip.. but there is little evidence of that as well.. a real mystery not likely solved untill the Post morten exam. Which I'm in no mood to perform, for a while at least.
Pesky oil level light decided not to show anything but it still lights up at ignition switch on.. sigh. Aything is repairable given enough $$ but likely the crank bores and head are damaged severely.
Short story: the thing is Toast. I need a transplant.. ANY one have any idea where to find one at an 'affordable' price.
What engines fit.. seen in my manuals that Maybe even up to 92?? might be useable.. advise on this ?
Thanx.

 

Give us you year and model and VIN# and I think I can tell you what will fit.

 

1986 FZ600.. JYAZEW003...GA 000345
Seemingly, according to my haynes/clymer it looks like an XJ or Radian 'fits'.. yes, there are small differences but I'm basically only concerned with fitting the engine mounts and clearing the frame members.. I do have an entire power unit to mix'n match bits from should the need surface.
Biggest problem is where am I gonna actually Find such a motor.. 20 years after production?

 

You need an FJ engine, not an XJ engine. The FJ is chain driven and a newer design. It is the same as the Radian engine, however. Considering that this motor came in 3 different bikes and at least 6 or 7 model years, you shouldn't have too much trouble sourcing one.

 

Hi,
I have an FJ600 that I've been working on for some time. Does not run the greatest, so I was looking for parts. Luckily I found an FZ600 engine (used) for sale at a local salvage shop. You might find one too.

Currently I'm in the process of replacing the top end of my bike with that of the FZ600 which I had reconditioned. I'm missing the right shims though.

Best of luck.

 

Thanx for the thoughts but I'm not having huge success yet . Although in fairness a local shop sez they can get one for $600 !?? perhaps a Wee bit more than the 'Boy' can afford and it seems a bit high to me as well. given the stories of $100 motors 'some' have talked about.
Are there any More in your Neighbour hood??
I can possibly rebuild the Seized one.. again.. Sigh. Given access to the needed Hard parts (likely a crank, (rods ?) and pistons.. a Risky road ..though as parts/machining can mount up really quickly.. soon exceeding the resale value of the Moto.. making this all a lot of work and sweat for no reason at all.
Having said that: Will you have any 'leftovers"?? although all is subject to an Autopsy.. which I'm in no mood to perform... just yet.
Shims are inexpensive.. and readily available from the local Yama Dealer.. IF you are willing to pay their labour rate (just drag in your head assembly) they will normally not charge for the shims (just swap 'em out), cuz they fit a LOT of yamahas and simply don't wear.

 

I agree with you, $600 is pretty much, but if it was in excellent shape, then I'd consider it. The $100 spare engine I got... well, was not in great shape. when I openened it up, lots of carbon buildup, valve seal guides gone, etc. The situation with my spare engine is that I was planning to replace the cylinder head, pistons, head, valves, and cams. I had worked on the spare parts and reconditioned them the best I could, hours and hours of labour. Then when I tried to install it two weeks ago, I broke one of the piston rings. It upset me very much, what can I say. So I can't use the spare cylinder head and pistons, and I installed the old ones back. So I have exactly what you would primarily need, pistons and cylinder, but I'm a ring short and the rings are aftermarket and a weird size. I'm not sure how to find a replacement. You need to figure out exactly what got seized. When I'm finished with the engine here I'll have lots of spares, for sure. I hope to finish soon, and then I'll be giving away most spare parts.
I should add that both sets of cylinder head and pistons have a bit of wear, but not beyond specs; should have good compression.

 

Custom rings are not realy hard to find and they can be had for less than $100 (usually a lot less but I'm going to fudge on worst case senario). Check with your local speed shop or machine shop, they can tell you what you need and source it for you (usually they like a challenge).

 

Robert, I don't want to steal the thread, but can't let this oportunity pass by without thanking you for your great input. I'll try your suggestion for the ring. It does hurt a bit to pay around $100 for a ring, when the entire spare engine cost me that much. But no time for regrets, I'll just go on and try things.

 

Thanx.. Have had issues with logging back on (Incompetence
Yes... Bits would be Great.
Found local wrecker with 2 engins one missing a cyl head for $300 and a'good' (i have not yet seen it) 91 radian engine for $700 ...Yikes! A lot of $$ for a 15 yr old.. a Good running FZ is 'mebe' worth $1500 on resale.. jit's tough trying to help the Kid's Wallet..But?
Strange about Moto Part pricing: Civic Ring set (4 pistons) is less than $50 retail (hastings brand) Full Bearing Shell set for $45 almost free by Yamaha standards
Ahh.. the price of non conformity.
Did pull the Fz's drain plug.. finally, darned thing was full of oil ??
Seize apparently was not due to oil loss.. Next is to pull the oil pump and check to see if it's drive failed (sheared the dinky little drive pin?) ...IF.. not an Oil issue then either something let go or it simply heat seized..Curious and curiouser

 

I've a fellow out here in L.A. who has what appears to be an 86 Radian 600. He's trying to get a lien against it (wife's ex-boyfriend abandoned it at her place) and wants it gone. I explained I would be willing to spring for the lien price if they would get the title. Has keys and everything. Should be had for less than $200. Possibly you might want to get it Danilo?

 

Price is certainly attractive.. thank you for your thought on this,
only concern is Engine condition, as always, and the ever prsent' shipping' costs to Vancouver BC although speed of shipping is a non issue so it 'may' not be silly priced.
Certainly I don't need that many parts Engine even, as I have errr.. Had a complete Moto. so I don't need that many bits off of it so perhaps all the parts other than the basic engine itself might be usefull to yourself or others here? a Group parts supply??

 

Wish I had the luxury of space, can't say that it would work out. The missus (bless her) gives me as much "space " as she can but there is a fine line in my collection that I dare not cross, lest I end up a bachelor once more. If I can convince her that I'm going to turn a profit on the purchase, she is usually a little more inclined to let me have a little room, but inveritably, I end up keeping the project 'cause I have way too much into it monitarily and emotionally. Drives her nuts.

The shipping might get a bit pricey but those cheep engines are far and few between
Good Luck

I found another but the price is way up there, but it looks like new!?

Great.... thanx for the thoughts efforts.
Do Like the newer FJ motor
Won't likely fit the old 86 FZ as the Carbs are almost downdraught on that model, the Gas tank being mostly Airbox on that year/model.
Likely My FZ cylinder head will fit though
Again as the first seler sez "shipping' will be pricey.. these motors ARE surprisingly heavy things, the crank alone is V heavy
Will have to ask re costs.

 

Yes, the entire head and cylinder block will fit just right. I did it the other way, I have an FJ motor, but bought an FZ spare which matches as far as I can tell. I am now using the rebuilt top end of the FZ on my FJ (head, valves, cams).

I do have a spare FZ set of carbs in what appears to be exc shape if you ever need that kind of thing. Appears to have been re-jetted though.

Good luck getting your bike back to a useable form.
