I assume that the 1300 has all the updates to fix a lot of the quirks that my 2006 1200 had. I don't know if a 1300 has any of the hesitation, bucking, or other throttle issues but If it does I would get the booster plug and install it. I installed one on my bike and it straighten up almost all of the throttle type issues. It really works and I recommend it. My recommendation change your brake fluid once a year, change the final drive oil once a year to avoid service problems. Other than that, have fun and enjoy. Pretty bike.
Agreed. The Booster Plug makes a somewhat-problematical fueling response a lot better. It makes the most difference at the smallest throttle openings, which makes the bike much much more driveable in town. And predictable as well. I use to sweat bullets making left turns in traffic when I would crack the throttle, feather the clutch, and .... the engine did not respond and I stalled it. Now the bike responds as it should. No issues in the last 4 years. I bought a 2015 K1300s MS in October 2014, added the booster switch the following spring.
Some other useful changes I've made:
1. Grip Puppies Only about $12, but they make the handlerbars fatter (better for my hands), and softer, and they soak up some more of the high RPM vibrations. A no-brainer.
2. Fiamm horn The weak 'meeper' is now a proper 'beeper'. Not really very loud, but the stock horn is a joke.
3. Switched power outlets I added a power distribution fusebox (it doesn't do anything other than hold fuses) under the seat. It has a 'trigger' wire hooked to the taillight such that the thing powers on and off with the bike, like a Canbus circuit. From there I added two outlets in the front fairing (in front of your hands), and I ran a connection to the heated seats as well.
4. Heated (Corbin) seats, front and rear - This depends on where you live and when you ride I guess, but I find it surprisingly useful and wonder how I ever got through cold weather in the past. Along with heated grips I've had a real eye-opened on how much better a bike could be with some heated bits. (I also have, but rarely use, an electric vest).
5. Tank bag I've long been a fan of tank bags, dating back to 1976, an R90s and an Eclipse bag. I find them the perfect place to put stuff on a bike as the weight is where it should be. I also love having a map pocket, and the BMW bag I'm using has a cell phone depression in the map compartment. I put a gate opening transmitter in there (gated community) and also my garage door opener. Now I press a button as I come to my gate and it opens. I then use the garage door opener as I'm coming to my house, just like the car. Inside the tank bag is a radar detector (Bluetooth to speakers in helmet so no wires), a tire repair/inflation kit, a change of gloves and a bunch of odds and ends.
6. Corbin back rest to go with Corbin seat. My late wife refused to ride the bike without it, fearing she would come right off the back if I accelerated suddenly.
7. Sport panniers I couldn't own this bike without bags. There is NO storage space on it without adding a bag of some kind. Want to buy ANYTHING at a store while on the bike? Need a bag...
A note on the tank bag. Unlike every other bike I've ever had, the K1300s has a weird wind pattern when the tank bag is mounted. It may be my height (6'2" with long torso) and/or lower Corbin seat, but there is a severe wind ripple that comes down my chest at speeds over 70mph. With my light summer jacket, the whole front ripples, and it does this severely. If I lean forward into the bag, no problem. If I lean back a ways (difficult to do with low bars), no problem. I solved the problem by taking a small waist bag and just hung it over the tank bag. Rotated the bag to the rear and it blocks that wind entirely. Rotate to the front in hot weather if I want more air flow. Easy peasy.
Some less-used stuff I added:
1. center stand I almost never use it, but when it's needed it is very handy. I used to have a K100rs (1985) for 30 years. If left on the side stand, it would smoke on start up. (Old timers know exactly what I mean.) So I used a center stand 100% of the time. Also made it easier to fuel. The K1300s doesn't smoke, and I have found no difference in fueling with the bike level or on the stand. About the only time I've used it in 4 years was when I had a flat tire on the road.
2. Luggage rack - Less used, except when I travel. I hate hanging weight off the rear end, and I use a tank bag instead of a tail trunk. The rack doesn't hold a lot, but it is appreciated when I tour. I like having the small BMW Softbag on there, but you have to remove the Corbin backrest to fit it. My late wife liked it as a backrest if it was packed reasonably full.
Stuff I'm thinking of doing:
1. Poking a hole in the gas filler tube inside the tank, so it will fill quicker. This is -by far- the slowest bike I've ever had for filling the tank, and it's only a 5-gallon tank at that.
2. Some sort of LED headlight These don't seem sorted out yet for motorcycle use. Nothing I've seen is completely plug-n-play, basically involving locating a ballast or dealing with cooling. As I live in a very hot climate (Phoenix), I'm concerned about my lights overheating and shutting down.
3. Some sort of GPS - If I had Verizon, I could possibly use a cell phone for GPS in the country - but I have Tmobile. Also, when I have tried to use the phone inside the tank bag map pocket for GPS purposes, it overheats, the display LCD turns black, and it shuts itself down to cool off. A huge problem with the BMW GPS (besides the price) is the mounting location, which seems to be right where my tank bag needs to sit.
