Hello everyone! It is holiday season here and I've been riding like crazy enjoying the bike, with the riding season coming to an end in the next 2-3 months, I would like to change every single bearing on the motorcycle and service my forks aswell. Does anyone have a bearing kit that comes with all I need in mind? (front + rear wheel, steering etc.) Hope I find everyone enjoying their rides! Thanks in advance.
 
It's your money, so feel free to spend it anyway you want...but replacing things that aren't worn seems like a waste of time and money. I'd rather have the original bearing that are working fine than aftermarket ones that wont wear as well than the originals.

But if you must, AllBalls make great bearings...just not as good as the ones that shipped with the bike. Be sure to change the pistons and clutch plates will you are at it...

Oh, I'm not talking about crank bearings etc, just wheel bearings and steering not engine wise. I might stated that wrong
 
No problem...I was just trying to be funny

I would inspect the condition of the bearings. If they aren't showing signs of wear on the balls and race (pitting and/or discoloration) I would repack them with marine-grade grease and not worry about them.

Regarding the forks, a basic oil change is always a good idea. I don't know the mileage of your bike, but you may want to inspect the bushings for wear. You will need to split the forks to inspect the bushings and that will require a seal kit.

In my opinion, if you are going to split the forks you should consider upgrading/modifying them with Gold Valve Emulators and straight-rate springs. By doing so you will eliminate brake dive and improve ride and handling. The modification converts the damping rod fork into a rate-based valve fork with adjustment for compression damping and some limited adjustment for rebound as well (via oil level).
 
Sounds really good Gary, I will check the Gold Valve Emulators and straight-rate springs. About the bearings I feel some weird vibrations on the motorcycle which is why I'm itching to do this, In addition I ordered the TBSync tool but it will take sometime to come to me so I thought having in mind the bearings would be a good idea.(I guess? ;p) The bike has 70k km (just passed them) and it runs very good aside from some heating issues I had. I want to take care of her so she lasts another 70 and more!
 
Vibrations could be many things:

As you mentioned, bad wheel bearings. This can be confirmed by slightly retracting the brake pads from the rotor and listening to the wheel as you spin it by hand. It should be quiet. Of course for the rear, you's also have to remove the chain. I also check for any side-to-side play in the wheel when moved to the side at the top or bottom of the wheel.

If the vibration seems to be speed dependent, and doesn't appear until around 60 mph (100 kph) the it is a wheel balance or tire related issue.

If the vibration gets worse with rpm, it could be out of sync TB's or ignition wires.

So what are the symptoms of the vibration?

Okay I quickly checked for side to side play, there's none. In addition the wheel is balanced, I recently changed the tires and they were both balanced(I was there).

The vibration does get worse with rpm but I also feel it when on low rpm sometimes which is weird.

By ignition wires you mean the coils? I'm about to search that up, however the vibration is really strong sometimes my right hand goes numb most of the times.

Thanks in advance Gary!
 
By ignition wires I am referring to the wires themselves. There is a known issue for the FZ6 where the caps on the wires con work lose. The fix is to 1) twist the sparkplug caps to make sure they are tight, and 2) if lose, use a zip-tie to secure any lose caps.

To get more info details, do a google search for "600riders sparkplug caps". This is the "sticky" in the technical section of the forum => https://www.600riders.com/threads/vibration-a-cure-for-bad-vibrations-spark-plug-caps.48874/

Looks like I found me some work to do tomorrow! Appreciate you Gary!
