Thank you, this is super helpful, especially about the shock spanner punch!

Yeah, I know about the wrench, my question is if it’s even possible to use it if the ring is way up inside the bike instead of closer to the rear wheel like on the stock shock. And I bought the shock used, sprung for a rider slightly lighter than me.

I recently bought a Wilbers type 641 for my 2015 FJ09. While it has preload, rebound, and high/low speed compression adjustment on a reservoir, the preload adjustment is mechanical. Unlike the stock shock, however, the preload ring is at the top of the shock, while the rebound adjustment is at the bottom. How on earth are you supposed to adjust the preload on these types of shocks? When installed on the bike, wouldn't the preload ring by pretty inaccessible? I'm pretty sure I can buy the hydraulic adjuster separately if it comes down to it, but I'd rather not spend that extra $350 unless I absolutely had to. Besides, I'm not sure how difficult installing it on the shock would be. If anybody has experience with mechanically adjusting preload at the top of the shock on these bikes, I'd appreciate the input! This seems to be a common configuration for fully adjustable shocks, so not specific to my model.

Wow, what a profoundly useful comment.

To clarify, it seems I’m unable to unload the transmission at all after putting in this god-forsaken “upgrade,” rendering the bike unusable.

I’m at wits’ end. I have no idea what to do. The new clutch plate stack is within spec. We’ve installed EVERYTHING correctly. Although I’m using the original part number clutch cable (the one with the weird bend that frays the cable over time), this shouldn’t affect the bike’s ability to disengage the clutch with the lever in, especially since it’s been adjusted to be as tight as possible, and I had no issue with it previously. I think it might be something having to do with the push lever assembly that engages with the push rod. It seems to “lock” instead of bringing the push rod and clutch plates out away from the engine. We can’t feel that spring tension. What could possibly be happening here?

Ok, this was super helpful advice, thanks! It’s not an Mccruise unit, but something that I believe used to be distributed years ago until the company went out of business. I found a video on YouTube of somebody who had the same unit on the same model year. He talked about wires from the CC being soldered into the ECU, but nothing about flashing it. Would I be ok with a flash? Is this a similar setup to the more modern Mccruise units?

I bought a 2015 FJ-09 about seven months ago, and one of the best mods the previous owner made was installing an aftermarket electronic cruise control. I’m currently trying to get my ECU flashed through Ivan to smooth out the surging at low speed and the on/off throttle. When I mentioned to him that the previous owner had this modification done, Ivan said there might be a potential problem. If the CC is plug and play, and not flashed into the ECU, then there shouldn’t be an issue. However, if the CC was flashed into the ECU, then when Ivan does his own flash, the CC might not work anymore and that would be irreversible. Part of the problem is that I don’t recognize this cruise control. It doesn’t look like an Mccruise model, and I no longer have the previous owner’s contact info, or I would reach out to him. So could anybody here possibly tell me about the CC I have on the bike? Picture is attached.

Thanks man, this was helpful!

Sure, but my issue isn’t one of MPG, it’s the actual capacity of the tank being different enough from what Yamaha advertises.

A couple of weeks ago, I took ownership of a 2015 FJ-09 with about 17,000 miles on it. Now, I love the bike, but I noticed immediately that the gas gauge was pretty wonky. When I filled up (I'm in the US and use 87 AKI gas without any ill effects), my first bar would disappear after 45 or so miles and I would be on "reserve" between 110-115 miles. I figured it was just a quirk of the bike; I'm good at math, and based on miles ridden compared to how much gas I was filling up (46 MPG for me, and this is more accurate than the bike's own MPG calculations) I knew that when I hit reserve I should theoretically have just under half a tank left. Tonight I ran out of gas. I was at almost exactly 160 miles. I'm very lucky that this happened on a two lane road, where I was able to easily pull over, instead of the middle of one of the busy DC area highways where I live. Now, while I had been running on reserve for quite some time at that point, I knew I still should have had at least half a gallon left, if not closer to a gallon. So I of course was very confused and frustrated. I called AAA and had them come fill up the tank with a single gallon. Then I took the bike to a gas station maybe two miles away from that point. I didn't insert the nozzle all the way, thinking that maybe the sensor that stops the tank from being overfilled was too high in the tank. And while this did create a little spillage, I was only able to put in 3.2 gallons, maybe less due to the bit I wasted. The math doesn't add up. That's around 4.2 gallons of gas, and Yamaha claims that this model holds 4.8. The bike is missing 12.5% of its tank! Where the hell did it go? Is this a case of significant false advertising on Yamaha's part? Sure, in a car missing 0.6 gallons isn't as big a deal, but that's nothing to sneeze at on a bike. Or is there some mechanical issue that could cause my bike to not use the full capacity of its tank?
