Wife & I just got back from Sturgis last night, rode almost 5000 miles total... had a blast... Well bout halfway out there I started noticing when accelorating in any gear at about 2800-3000 rpm range, I was getting a new noise (rattle sound up front). The noise would stop happening above that RPM range. Orginally attested it to gas, as out west only could get 91 octane... but that aint it, its still did it when I got back home yesterday. I checked tighteness on engine guard and highway pegs etc while out there. I tried keeping my feet on highway pegs and using pressure... but no change. The 09 has the engine brace up front and top, think that might be it... it seems to be able to move around alot and could rattle IMO. Thats next in my T/Sing. Looking for any other suggestions opinions. My worry is lifters.
Bike is 09EGC, just turned 16,000miles, with Fuelmoto Jackpots/Stage 1/PCV. Running amsoil 20W50, Amsoil heavy in tranny, and HD primary/trans in primary. Noise sounds like its coming from top front of engine area.
I have an 08 Ultra that does the same thing, it rattles loud enough that I can hear it over the radio and pipes. I am running the same oil as you and was thinking that the syn oil might contribute to the noise. I am pretty sure that it is in the top end also maybe the lifters. I took mine in to the dealer and they told me that it was normal engine noise. I didn't expect anything else from them, I have owned nothing but Harleys since 1975 so it's not my first rodeo, but there is a noise that is not normal.
I have been cleaning the bike all day. I pulled the highway pegs off and checked and rearranged heat shields. Checked torque on the top fwd engine mount bolts. Nothing changes it. It's due for oil/service, so I may try a different oil to see if it makes a difference in top end noise. It is only doing it between 2800 - 3000 rpm under load. It does not do it otherwise. I thought of maybe increasing fuel in that range with the PCV, just not sure at what percentage of throttle to do it at. It is a lot warmer now then it was last month here and thought it may be a tune issue because of that.
EDIT: I just switched over to windows to have a look at the tuner settings. I am using the fuelmoto tune for my setup. At 2500 cyl 1 seems kind of strange to be removing fuel in this RPM range, which also is the rpm range where I am having issue. The rear cyl is similiar. Is this because this is the cruise range and it will increase fuel mileage maybe? I can't get the table into here without thinking apparently
I had developed a new "pinging" sound on my '05 EGC. I happened to look down and noticed that the front shifter lever was moving a lot more then I remembered. Check when I got home and sure enough, it need a small 1/8th turn and that solved it. That problem actually made the bike sound like it had an engine "ping"
The stock ECM is rich in the transition after 40% throttle because you are coming out of the closed loop lean mode and this is done to ward off detonation as you accelerate into the power mode. That is why you will see negative numbers on your map. You may want to bump those numbers up and see.
...and so I bumped both cylinders up in the 2500 - 3000 rpm range and the 40, 60, & 80% throttle roughly 3-4%. The noise is gone. All I hear now is the normal top end noise...
