The 14kg spring equates to 784 lbs...... near enough 800, which is good for a 190-200-ish lb rider and yes you can tweak the preload if necessary. Don't know why they'd call that a Gen1-2 shock, it would work for a Gen3 as well. Adjustable ride height is a bonus.... betcha it goes on the centerstand a bit easier now. Rod for adjusting preload is also a nicer feature.

I don't think I'd want any less of a spring......

Compression damping too? For that price, super bonus.
It would have come with a standard preload they set for the spring, and if it works for you, then don't change it. Your numbers seem ok to me.
FYI, for every inch the tail of the bike sags, that only equates to roughly a third of that at the shock..... suspension ratio is 2.7:1.......

Gonna ask what Gen you put this on? Do you have OEM springs up front?? If Gen1/2, wind them preload adjusters all the way in, woefully undersprung up there.

Apparently YSS does not have a G Series shock fitment for the FJR.

YSS Suspension (Thailand)

Most likely (and I'll almost bet money) there isn't any room on an FJR for a piggyback reservoir....

Yes that's a bunch of miles, but may not be worn out. Will you notice with an aftermarket shock, that depends on where you set it.

One way to test that is increase the rebound damping.... looking from the bottom, turn the rebound adjuster fully clockwise until seated. You then back it out X clicks to the damping you desire. Make note of the number of clicks you had it on.... if you were still at the Yamaha standard of 12 clicks out, then you had little damping to start with. If you had it 6-, 7, or 8 clicks out, then you had some damping..... now reset it to 4 or 5 clicks out. Should be much harsher, and a tad too harsh.
So whatcha got?? Where did you have it? Feel the difference at 4-5?

Also while you're under there, is the lower part of the shock covered in oil and all gritty from road crud? If only minor, it may not be leaking. If quite oily and no damping, then yep, it's done.

If the shock is clean like that, it means you didn't leak out any oil that would lessen the rebound damping, confirmed by your 5 clicks feeling hard. Springs don't really weaken much, but the OEM rear shock is only ~650 lb/in on SOFT and a 200lb guy needs 800-850 lbs/in on an FJR if going aftermarket shock. So, slightly too weak anyway, and one tries to compensate by dialing in some more rebound (say 6 clicks out, maybe 7) to keep the bounce down. Sag wiil be what it is..... put it on HARD and now you have a ~950 lb/in spring, just a tad too stiff. One would back off the rebound in that case, but still a tad hard spring.

As for the forks, there are progressive rate springs in there and you should have the preload almost all the way in if not all the way in. This will lessen brake dive as the first weaker part of the progressive spring compresses. As for damping, you can adjust compression and rebound...... I always say start at 8 clicks out and tweak from there based on your style and preferences.

Best bang for the buck on the front is the Traxxion spring kit. With it, you'll run preload at minimum or thereabouts. No more brake dive, so tweak the damping again......

 

[RaYzerman]

Get the Traxxion fork spring kit..... plug and play, EZPZ-ier than the RT's (for which you have to cut your spacers). I don't think the RT come with the plastic sleeve things, they're extra.

 

[RaYzerman]

The spring rate is just fine. You can just slide in the new springs, but you must lower the oil level..... use a syringe and a hose with a zip tie at the 130-140mm length, then suck out the excess and that's your new level. If there's a different level noted in Traxxion's instructions, use that instead.
If you have a Gen2, current oil level OEM is 100mm, so you'll have to remove some.
