After a shocking amount of dithering, I have installed the AF-xied fueling device and Beech’s Beefy 31mm Suspension Riser Plates™️and done a brief familiarization ride.



Preexisting Issues:

Handling - I love the freight train stability of the stock K1300. But on spirited rides on unfamiliar twisty roads, the need arises regularly to tighten your line mid-corner or to rapidly initiate or reverse a turn. The K bike is not terrible at any of that, especially for its considerable length and girth. But, it’s not great either. Install of Brother Beech’s 31mm rear ride height raising suspension plates completely eliminates this problem. Direction changes, reversals, line changes, trail braking... The bike now feels like a slow-steering Superbike rather than like a slow-steering sport touring bike. I have no noticed any loss of my much cherished stability. Install was easy. I cleaned the dog bone and re-lubed all the needle bearings while I was down there. It’s a low-mile (5,600) 2015 bike and the bearings were fine, but I agree with whoever said BMW loves to save money on grease.



Fueling - these bikes are mapped too lean to run right. Period. The manufacturers are likely going to be forced ever further down this snake hole to appease moronic European bureaucrats set on appeasing Greta Thunberg. The high point of motorcycle fuel injection driveability was probably a couple years ago. When braking into a corner on closed throttle, the system shuts down injection altogether as revs drop below about 3k, creating a massive spike in engine braking. As you let off the brakes and begin rolling on the throttle, the pickup from closed throttle is way too snatchy. And if you need to close the throttle again to tighten you line, the ON to OFF throttle transition is just as bad. It’s just too lean at small throttle openings. Enter the AF-xied. There’s tons of information out there on how this device works, so I’ll describe the install and riding impressions. The install requires removal of the gas tank because the connector for the O2 sensor is perfectly hidden behind the upper frame rail where it turns from mostly vertical to mostly horizontal. Basically inboard of your right knee. Open the connector, plug the male end of the AF-ied harness into the female end of the OEM connector and vice versa. Route the grounding wire up to the battery negative post. The actual little box for the device has about an 8-10” pigtail and snaps together with the one on the rest of the AF-xied loom. I mounted the little thumb-sized box to the upper right side of the oil tank using 3M Dual Lock tape.



Anyhow, the snatchiness is gone, the bike fuels very cleanly from any rpm, the OFF/ON/OFF transitions are completely smooth at all rpms. I was expecting the system to take longer to unlearn its trim maps before any difference would be noticed, but it was immediate.



In short, both mods are transformative. It’s been a long time since a mod I’ve bought had zero downside, zero disappointment. Both of these fit that description.



Well done, Beecher.

Bill, my ‘07 K12R suffers from exactly the same fueling issue you described before the mod. It makes riding the bike smoothly in the twisties nearly impossible and destroys “flow” when riding. I’m assuming the afxied device works the same magic on the K12s?

Beech, how did you decide on 31? Did you try other sizes?

Fastdaddy, can confirm, the af-xied works perfectly on the K1200 as well.

Do you know of any retailer in europe? would like to try this but price would be scary to order from the states. $200 for the unit then shipping to sweden and once here add 30% taxes on both the purchaseprice AND shipping.

I assume it works as well on the K12s. It’s the same part number at Beemer Boneyard. Weirdly, it’s the same part number for the F800 as well.

Easily worth the 209 simoleons.

Sorry Mattias, I don't think there are any European retailers. I was lucky to have a friend in the states who took delivery and was coming back to Ireland to bring it to me.

Whereas my other friend who fitted one took the hit and bought it from the states, delivered to Ireland. He paid the customs duty etc.

The O2 sensor is quite expensive. You’ll know when it needs replacing because the engine will run rough. Otherwise not worth doing. If you have a GS-911 you can test the O2 sensor in real time.

The 31mm lift plate was used in the European Power Cup series years past when stock K1300S bikes were used. Lots of feedback from their use. These are available also from European sources.

A word of warning about Beech's riser plates...



You will absolutely love them!



Improved handling and stability. Huge improvement and low cost. Bike will lean like a gangster when on the side stand due to the lifted rear end; you can mitigate this with a club-foot type riser fitted to the bottom of your stand. I'm in SF. the increased pitch helps when parking on hills, so I'm good with the gangster lean.

Very happy with the 31mm riser plates after putting more than 50k miles on them. (y)

Well done, Beecher.
I bought the 25 mm plate from Germany but it has no instructions.
I changed the dog bones on a Bandit with a bottle jack.
Can you give me a general idea?
Is a single swing arm stand enough?
I still have the breaker bar.

Cannot lift the bike on swing arm when changing the plates.

Use a steelrod/tube through the frame and a jack on each side of the bike.

Beech if you decide to produce more 31mm plates I would be on your waiting list. 🤞
