I'm thinking more like pellet proof.

 

Had the same issue with my 2012 103 Classic. Ran fine the first 5k miles till got overheated in a traffic jam. It would never go away. Took to the dealer 9 times and they could never figure it out. Always came back with "the bike is in specs so it must be bad gas". Even though it did it with "their good gas" Dumped plenty of octane boost in it and still was there as soon as the bike was fully warmed up, and even did it with a hard throttle starting at over 3000 rpms. When I drove it real easy would sound just fine. Cured the problem by trading it off for a 13, but still very disappointed that HD could not find how to fix and would just give me the bad gas cop out answer.

Is this not the way it goes?
Anytime you take any piece of equipment or a vehicle in for repairs, the mechanic engages you in conversation about the product. He is looking for clues as to what you "think" is wrong. Somewhere in the conversation he gauges your mechanical aptitude and comprehension about the product. Within minutes he will decide (in his head) if you are full of BS or you actually know what you are talking about. If the problem makes reasonable sense to the mechanic, he will make an attempt to troubleshoot it. If he determines your problem to be unreasonable and a nuisance to him, he will give you BS answers to your questions. "They all do that", "that is normal", "why don't you leave it here and we will see if we can make it do it" and my personal favorite, "It is in specifications". It might burn a quart of oil every 1000 miles and the crankshaft is sloppy (but that is in specifications)?

At that point you need to load your stuff and take it somewhere else for a second opinion because you have gone about as far as this road is going to take you.

 

Another good case for being able to lane split, eh? If getting caught in heavy traffic is a normal thang for you, once you get this sorted out, I'd certainly recommend researching and possible installing cooling fans, ugly as some of them may be... There are some on here that aren't ugly at all, and if I was in a state where I had to sit in traffic with my thumb up...mmmm, well...I'd install 'em, and I've only got an 88!

 

2012 touring bikes already have one.

 

Agree totally... Pinging or spark knock is one thing... Detonation can result in engine failure. Fixed through tuning... Good luck.

 

I'm glad I've got one of them bullet proof 103's.

Just don't shoot me in the radiator....
