I bought my vintage in November, It now has 5700 miles on it. I began having issues with the engine at around 4000 miles. The valvetrain always a bit "talkative"- but nothing I would consider excessive, think EVO sportster. At 4K, when the engine would get hot, the rear exhaust rocker arm started getting louder and louder. The front joined the party at around 4300 miles. I dropped it off at the dealer a couple times, but the tech couldn't reproduce the condition (usually takes about 30 miles or so at highway speeds- pretty good chunk of time). Volume of the valvetrain seemed to increase daily. It also began to run really hot at idle- hot enough that the pipes glow if it sits still running for more than three minutes. Both the exhaust heat shields have the chrome heavily discolored because of this. It also began to misfire and idle really low when hot (less than 600 rpm). After I got the 5k service done (and being admittedly frustrated when they told me they couldn't reproduce the condition), I rode it in there hot, and rapping away. The tech stopped what he was doing to take it out, and asked that I leave it- which I did. He said he had heard it, and it was definitely not normal- so he filed an "ask polaris" case. Fast forward two weeks- The tech finally gets an answer- basically that it hasn't failed or locked up so if I want it fixed, it will be on my dime unless I can prove that any component is defective. The polaris tech then went on to chide the service tech and myself stating that (i am paraphrasing) "V twin engines produce heat and noise" and that "he was unable to change those characteristics"- as if neither the dealer tech, nor myself had any experience with motorcycles. I have been riding on V twins for decades. This thing is louder than a shovelhead with bad rockers when its hot. It does not sound like a 20k motorcycle, it sounds like an impending failure. The thought of the motor losing power on my daily commute (40 miles, one way on the interstate in heavy, fast moving traffic) or locking up is not a pleasant one (and possibly could be a terminal one). This is not what I consider good customer service from polaris. I spoke with the owner of the dealership Saturday, he agrees with his tech and myself that the noise is not normal. He said he is going to attempt to go another route to get a polaris tech out to listen to my bike, and if need be, fix it out of his own pocket. Like I said, the dealership I purchased it from has been great to work with, but other dealers may not be as accommodating. So while I can (and do) wholeheartedly endorse Indian of Fort Hood, I cannot say the same for polaris at this point. A warranty is worthless if they put the the burden of proving a mechanical failure on the customer's dime. The noise, heat, and misfiring should be an indication that there is something amiss- I should not be required to ride it until it completely fails (see also; the scene of the crash) before they are willing to stand behind their product. With all of that being said- If you're planning on a purchase, ride several, buy the quietest one. I have two friends who also ride Indians- both their bikes were MUCH quieter than mine ever was, so it isn't all of them. Get to know your dealer, as they may be the only ones willing to stand behind the product.
