Put baffles back in and engine knocking stopped
2017 Road Glide I just bought from HD Columbia TN 3 weeks ago: The previous owner added Stage 1 and S&S true duals. The baffles were in the saddle bag and obviously never used. I also found the V&H FP3 in one of the bags. Over the last three weeks I noticed valve chatter quite a bit; it seem to get really bad once the engine warmed to normal temp and experienced even the slightest load (slight up hill, etc.) despite any amount of down-shifting. The pronounced valve chatter would last for several minutes then ease off for a while. Well, this morning, I put the baffles in and plugged in the FP3. I checked the current mapping which showed High flow dual exhaust with baffles. So I set the FP3 to auto tune and left it on the bike. I rode for around 20 minutes with soft acceleration then hard acceleration a couple of times. I was able to do a 3 mile stretch in 6th gear then turned around to repeat as heading home.
I heard NO chatter except briefly during a slight incline in 6th while using cruise control but it immediately went away.
Did placing the baffles back in make this kind of difference? Did the FP3 auto-tune start adjustments right away? Whatever the influence, the engine is not sounding like marbles rolling around in the heads and I just hear the slight normal whine and sweet rumbling,
Thoughts or experience with such a thing?
