I have an 2010 FLHTK 3500 miles with Vance and Hines Big Shots Screamin Eagle cone intake and Screamin Eagle Race tuner, the dealer I bought the bike from did the mapping and dyno. My problem is I am hearing a tick from the left side of my motor at approximatly 2500 to 3000 rpm 3rd or fourth gear. I did start hearing the tick before I did the mods. I took the motorcycle to the HD dealer and they test drove it a couple of times and asked if I was using synthetic oil and I was using HD synthetic at the time and they told me was normal to hear the valve train with using synthetic oil. I have switched to Mobil 1 v-twin 20w50 synthetic since the and still here the ticking. Has anyone heard this before? Can I take it to another dealer and will the honor my warranty which is still in its first year?
