I have a 2013 ST Limited so I will share my experiences. Currently have 13000 kms (8000 mi) on the odometer. During the week mostly short trip riding and on the weekends going a full tank of gas without stopping is not unusual.
Rider comfort.
Right leg is a lot cooler on the ST as compared to my 09 GS before putting the Spyderpops heat control items and similar but still cooler after. Upper body is about the same as the GS except when stopped in traffic because of the heat rising out of the vents around the handle bars. When moving air is being drawn in this same vent so heat not an issue. Left leg was brutal hot. It felt like a volcano vent coming out from under the seat and I found it extremely uncomfortable on hot days. The body panels on the left very hot to the touch. The gas cap is very hot, could not hang on to it for very long with bare hands.
Heat control.
I added foam rubber under the body panels to block the air from exiting the body work under the seat. First I was only going to seal the left side because I wanted to stop the hot air on my left leg. Because it started to come out that some were having trouble with melted MC’s I assumed the relatively cooler air coming out the right side of the seat would do more good going down over the MC than coming out under the seat.
My comfort was greatly improved. No more hot air on the left leg. The left body panels behind the foam block are cooler to the touch and as a surprise to me the body panels in front of foam block was cooler to the touch. The gas cap was cooler to the touch. Now I still find it a bit hot under some conditions, but it is much better. As an experiment I went riding in shorts one day. That is not something I normally do. It was 85 degrees and sunny that day and found it not too bad except when I got into stopped traffic due to road construction. When I got home I measured temperature of the left body panel just in front of the seat and it was 105 degrees F.
MC recall result.
At a little less than 12000 kms (7000 mi) I had the recall completed. The dealer found no melted or damaged parts.
Problems reported by other owners.
Faults or codes due to heat I have not had any.
Rear cylinder running lean I have never checked the plug color. So I just don’t know.
Smell of gas. I have never had this problem with my ST and it is always parked in the garage. I did have this issue with my GS from time to time.
Makes the garage hot. Of course it does, but no different than my GS did. This is subjective of course because I did not think of it as a problem.
Shudders when taking off. Yes my ST does this when cold only. When I back out of the garage it will do it. When I take off on the street it will do it again. When I get to the stop sign a half a block away it will take off smoothly. It did not do this when new.
Boiling gas. I have never noticed this either before or after adding the foam.
Stalling. It did do this 4 or 5 times and only during idle when started cold. Has not done this recently.
Conclusions
A lot of what I have said is subjective but I tried to be as accurate and honest as possible. For me heat is no longer an issue. The recall has fixed the chance melting bits and the foam I added has improved my comfort. It is also obvious that others experiences are different. In no way do I want my experience to belittle the problems others are having. It is my opinion that there is more than one cause to the problems ST owners are experiencing. When there are multiple causes it can be very hard to find the solutions.
