I bought my 2015 FJ-09 used with the original chain and sprockets. I'm at 20k miles and the chain is definitely shot so I ordered a new one with some JT sprockets but I feel like my sprockete, especially the rear one, show very little wear. The front one definitely looks like it has some shortening/flattening of the top of the teeth but the rear one hardly shows any wear at all. I bought the heavy duty RK chain so I'd like to get 20k miles out of it but would hate for the sprockets to wear before then. At the same time, it would be nice to save $40 and keep the new rear sprocket for the next chain and just change the front one. What do you guys think? First two pictures are front sprockets, the rest are rear.

All solid advice, thanks.

Fair enough. Email sent. How much do you weigh exactly? You don't think the 10 NM springs were too stiff? I went back and forth between the 9.5 and 10 but now I'm second guessing myself.

I pulled the trigger on some K-Tech 20IDS cartridges to match my Razor shock. Now I just need to confirm what fork oil to go with and what height I should be filling to. I weigh 250 lbs with gear and went with the 9.5 NM spring. I've done so much reading that my brain hurts but I'm still confused. Should I be looking for an oil that is approximately 16cSt@40? I think that's what I've gathered from my reading. It seems like the Maxima 5W racing fork oil matches that specification. Will that work is there a better suggestion? Also, what height should I be filling to? Thanks in advance!

That's what I wanted to hear, thanks. I plan to have them serviced every two years. I'm just going back and forth on whether I want to get the K Tech cartridges or spend the extra $200 for the AK-20s. If they last forever and I can put them swap them into a different bike, I feel like the AK-20s may be the way to go.

Good to hear you like it. I ordered one late last night but was going to just cancel my order if I could have gotten it cheaper. Got it on sale for $720 though so overall I'm happy with it.

I realize that this post was months ago but who was selling the Razor R? I weigh 240 also so I'd be interested if he still happened to have it for sale.

So after an unhealthy amount of deliberation, I ordered the K Tech Razor R rear shock today for my 2015 FJ-09. I think a big part of why I have been hesitant is I was unsure how long I was going to keep this bike but I have decided I'm in it for the long haul. I'm only going to be able to own one bike for at least the next 3 years and want one that I can go on long trips comfortably but also take it to the track for some fun once a month or so. After riding it over 8 hours from Florida to the North Carolina mountains for a week (The Tail of The Dragon obviously being one of the roads I hit) and putting 2500 miles on it in that week, I've decided this is the right bike for my needs. I just need to get the suspension sorted out. As someone that weighs 230-240 lbs, the stock suspension is just not cutting it. Removing the hand guards, flashing the ECU, and raising the forks 10 mm has helped a ton with smooth throttle, turn in, and reducing the speed wobble. But the rear tire bouncing when hitting the slightest bump leaned over and the front tire break dancing when I accelerate hard out of a corner just feels dangerous. I'm eyeing the AK-20 cartridges and a big selling point for me is the fact that they advertise being able to swap them out to a different bike by just switching a few parts. I'm mainly curious as to how long a set of these cartridges is expected to last. I think the long play for me is to have this as a dual purpose street/track bike for 3 years or so and then buy a dedicated 600 cc or maybe even liter track bike while keeping the FJ for the street. But let's say I want to put these cartridges in a track bike in 3 years after 40k+ miles, are they good for tens of thousands more? With proper fork maintenance, how long will these cartridges last? I was looking at the K Tech cartridges but I read a couple of comments saying these AK-20 cartridges are a lot better quality. For someone that wants to push this bike hard in the twisties and take it to the track, it seems like it's worth the extra couple hundred for the AK-20s. Thoughts?

I'm looking at the K-tech cartridge kit and RCU Razor-R shock. The Ohlins shock seems great from what I've read but not sure I can justify an extra $300 over the K-tech when they seem to be very similar.

What shock did you end up upgrading too? I think the suspension is going to be my next mod.

Thanks guys, I appreciate it. I don't really know how the internals of a shock work so I didn't know if it just reset to the lowest position or what. I'll just keep rotating it and see what happens. Probably going to replace it soon anyway.

So I was trying to adjust my rear preload to the max setting and rotated it one notch too far. It made a loud noise and I'm not sure if I messed something up. I can't rotate it back the other way now and I'm unsure what to do. Idk if I can just keep rotating it back around but I don't want to mess anything up so figured I'd reach out here.
