I know how to set rider sag (though I don't yet know what it should be on our suspension, nor how one determines that), 

If you watch enough of his stuff he explains it all. In one of the ones I put a link for he even gives some ranges. If you get there (static set and rider within his guidelines you are close) and probably wont need springs. We both will. If you watch some more and learn about the zip tie on the front fork that will help a lot. Like others have said it will still be trial and error. Besides weight, some are sportier riders and will need/prefer a stiffer setup. Others will not. In some he even gives it as a percentage (not specific mm) so you can look in the manual and do the math...

As for a suspension shop... that sucks.

BUT

Even your dealer can install a new rear shock, or replace front springs and or cartridges. It will be the specialist on the phone/web that will help you choose what parts. Then all the dealer has to do is install them. Not ideal but doable.

The rest is trial and error. The best part is that once you start adjusting you will be COMPELLED to go for another and another ride till you find just the right adjustment. Near any of the rear shocks that people have listed here in other threads will work better than stock as long as you give them your weight. I would start there. i bet you like the improvement so much you will immediately want to work on the front..

Don't have to find a local shop. Have received lots of free advice speaking to shops on the phone. My first couple of upgrades were done by shipping forks and sometimes shock to other parts of the country. Just had to be able to remove and reinstall forks and shock. Over time I learned to service forks myself so no more boxing and shipping but I still call these shops for advice and parts. It adds to the price of course but suspension imo is the top bang for buck upgrade regardless of type or pace of riding.

Hello all, 

Thank you for letting me join the forum.!

I have a Tracer 900 2018 in tech black.

I have 5500 km on the clock now and have been doing just city rides so far.

I have a new issue cropping up recently. When I lean into a corner, even at low speeds, I feel an instability on the front wheel and the bike shakes in the front.

I checked the fork bearing and it all seems good. No clue what is going on. Has anyone had this issue?

Looking for your feedbacks.

Thanks in advance.

How does the tire look?  Is there any cupping or uneven wear?

The tire looks fine. I don't see any uneven wear or any kind of spots/bulges. Looks pretty new actually as it's been ridden soft and only on good roads. The Wobble is slightly more violent when surface is wet but also quite noticed on dry Asphalt. Which is kind of concerning.

Hummm,

A couple of things related to wheel mis-alignment.  Not sure any of the following would help, but...

Have you moved the fork legs up or down in the triple clamps? If so are they set to different values?

Is fork spring tension set the same on each fork leg?  See owners manual for adjustment procedure.

Is front wheel aligned in the forks?  Loosen front wheel  pinch and axel bolts, pump forks up and downs to align them, tighten front wheel.

Is rear wheel aligned correctly in swing arm? Check w chain alignment tool.

Hope this helps

The wheels are both aligned perfectly.

I haven't tried to anything with the front fork yet, but have observed that the rebound is quite high. Could that be a cause? The only change I made was at the rear, and i increased the preload on it as i am a slightly heavy guy and observed the rear was too soft. 

Is front wheel aligned in the forks?  Loosen front wheel  pinch and axel bolts, pump forks up and downs to align them, tighten front wheel.

I shall try this out soon and test it.!

Yes, i did that the last time i adjusted the chain slack, with an alignment tool.

Hi, 

The tire pressures were set to 2.5 Front and 2.9 rear. 

Checked yesterday.

Glad to hear. It’s sounds like you may have checked everything out based on the other replies I read in this thread. You may simply have some cupping (tread wear unevenness) going on combined with suspension settings that need to be adjusted. Loose steering bearings can also cause this symptom. 
i can’t see your bike from here, it may be time to get another visual opinion on these and other components on the bike. 
keep us posted,

@Nik.munich, put the rear preload back to where it was and see if it eliminates the issue. If your problems started there, at least try to restore the bike to that point.

If that works, then you would be better to get a stronger spring, or even better, an uprated shock, that is better for your riding weight.

Is it only noticeable when turning one direction?  I've seen bent wheels do this, where the tire deforms under cornering load at a flattened portion of the wheel rim, but doesn't give any vibration while straight up and down, or turning the other direction.  

My other initial thought would be that it's thrown off a wheel weight, which isn't uncommon, but I doubt a wheel balance issue would cause this vibration at the low speeds you describe.
