From a purely length, stroke, and spring-rate standpoint the following are swap candidates. HOWEVER!! the clevis and reservoir location may preclude their use without significant alterations.

Is the FJ shock the same length/fitment as the FZ?
 
I see on the FZ-09 forums people are swapping shocks in from other bikes (ZX-10/ZX-6 etc.)

[pattonme]

Is the FJ shock the same length/fitment as the FZ?

If looking at retailer cross-references is sufficiently accurate, the answer is yes. Model YA335 for both. A lot of very naive people just slap in shocks without paying any attention to spring rate, valving, and stroke. Not saying these ZX or other shocks aren't a match (will need to dig up that FZ09 post) but if you do go that route, make sure to check ALL aspects of the fitment and spend the ~$200 to get it fully serviced.

Thanks! 
I always have shocks rebuilt/re-valved and re-sprung when I am swapping them onto my bikes. I'm north of 215lbs geared up, and there isn't much off the shelf that is setup for me.

[pattonme]

sorry @deersSlayer the website prices are USD. I called them and asked. At the end of August the website will be listing both and prices in CAN at least are going up. Today they are 'at par'.

Can anyone tell me the stock rear spring dimensions? I.E. 7 in x 2 I.D.
 
I think this the right place? I would like to just change out my spring, I did this on my 2002 FZ1 and rode it like that for 80K+ worked great.
I think a 700 lbs like on the FZ1.
I am a big dude (265 lbs) I ride two up most of the time and camp off the bike. B

Just happen to have one laying on the garage floor.....7 inches by 56mm id. Would give it to you all metric, but my mike doesn't go past 6 inches. 

[pattonme]

Added Eibach part reference. Just use the same series coilover. I've been doing this for years and not infrequently a third or half the price of "motorcycle specific" product application.

[brprider]

7.11/16 x 2.20. if you try it you do so at your own risk. I am just a redneck with a beer thinking out loud.
may be I will call and talk to them.
 
Reporter thanks for the starting point

[pattonme]

@brprider, why a 700lb/in spring? If 'baseline' is 550, that's one heck of a step up. I could believe a 600 or maybe 625 if you're a 250+lb rider. What spring calculator spit out that number?
 
Unless you can show the linkage ratios are the same what some other bike uses for spring rate is utterly irrelevant.

[brprider]

The bike weight is about the same as the fz1 was and the load is the same me 265 my girl 160 camping gear 85 lbs. Everyone said 700 was to big last time but it worked great. Later I found out friends had gone to 750 and 800. I think I would be ok at 650 and I may go that way. so stock is 550?
 
this is the O.G. spring info for the FZ1http://www.yamahafz1oa.com/forum/showthread.php?t=49139

[pattonme]

stock on the FZ09 and (reasonably sure) FJ09 is 550. 
 
Racetech claims the FZ1 came stock with 12.0kg/mm == 670lb/in stock. So when you put 500lbs of rider and gear on that subframe (was it even rated for that kind of weight?) you only went up to a 700 spring? I would agree with your other forum members, a 750 isn't unreasonable.
 
The only thing the FZ1 has in common with the FZ/FJ09 is the sticker that says Yamaha on it.
 
If you're going to put the same 500lbs on the FJ I'd carefully read the weight limit disclosure. And if I had to guess, a 650 spring.

[brprider]

that's the 06 or newer, FZ1 my bike was the 02. rear was set up for 130 lbs rider if I remember right.
REAR SHOCK SPRINGS
Recommended Shock Spring Rate: 16.835 kg/mm (use closest available)
Stock Shock Spring Rate: 7.6 kg/mm (stock)
 
as far as the rating. when you weight 265 some times you need to make it work.
Now would you tell your girl she cant ride? well we are just to heavy but I am ok with out you safety and all honey.
they say I can't ride a wheelie but I turn that TCS off.
My rack said I can only put 5 lbs on it. if I put the box on I am over the limit. than I put some junk in that trunk.
the rating is for liability.
 
FZ1 and FJ09
128hp 115hp
500lbs 462lbs wet
power to weight ratio:
.0256 .0248
26,000 mile valve adjustment
miles to a tank are about the same
for me its as close as I could find to my 2002 fz1 low end power and handling
 
 
thanks for posting the good info but lets not muddy up this up.
 
I ordered a 650lbs spring today. see how that works.

[pattonme]

There is something VERY wrong with RT's shock spring calculator for the FZ1. Either the OEM rate isn't remotely right or the formula is wrong. I compared with a Triumph 1050 and was also getting surprising rates even at low rider weight so either the leverage ratio is incredible or the formula for that one is wrong too. It wouldn't be the first time.
 
I would ask Penske/Traxxion for their input. I would believe something on the order of 20% stiffer rate for every 100lbs over 150.
