103 ping/spit

I'm wondering about a ping I'm experiences with my 2011 Ultra Limited. I use only high oct gas and usually Shell. When it's cold it runs like a champ, but as it heats up it pings (a lot), but to me a better word is like it sounds like engine spits. I would not really call it a ping, but maybe that's what it is. Going 70 it spits away, or actually at any speed, but not when stopped. I was told at the dealership to buy an additive that will increase my octane by 3. I have not done that yet, but plan to.

Is anyone else experiencing this, or is it just me? Also, I had a 2010 Ultra Limited I heard the spit once in a while, but traded for the 2011so I do not know if it would have developed into more like with this one. Just had my 5k at the dealership and it still does it. Thanks.

Have to be brutally honest - they all ping. Don't they?

Does it ping all the time when hot, or just when accelerating?

Mine does the same thing.....drives me nuts!!! I have to shift around 3k because I hear the noise. Most of the problem is due to how lean the bike is tuned thanks in large part to the EPA. I tried the additive they sell, Screaming Eagle Fuel Additive or something to that effect and it seemed to help in the early part of the day, but as it got hotter, the ping returned.

From what I have read and been told, tuning is the best way to get rid of the ping. Get the AFR around 13.4

If the EPA wasn't dictating emissions, these motors would be tuned perfectly. Yet.....having them so lean hasn't really improved the air quality has it?

As a genuine ping will eventually destroy the engine, I would expect a Moco recall or re-program being issued for these machines. Start making a stink where you bought your machines. The required change may be very small, as I see most of those with the problem are very close to sea level where compression pressure is the highest and therefore requires proper tuning and honest rating of the top octane fuel. Tried switching fuel brand to see if anything changes? It may turn out that "Kwik Stop" fuel just won't cut it in these machines. Keeping the heat concentrated near the head with the head pipe catalyst location doesn't seem to be the smartest design choice either.

I dropped Amsoil in all 3 holes (SAE 20W-50 Synthetic Motorcycle Oil in the engine and primary chain, and SEVERE GEAR 75W-140 Synthetic EP Lubricant in the transmission), and use an Amsoil EA oil filter. Makes a world of difference. Runs smoother, cooler, and quieter (less tapping).

Fuel ratio control !

Hi , If you have a friend that has a 2008 Harley Ultra "borrow" his 02 sensors ( 2 ) . I believe this will save you tons of money & hard hot labor and are very accessiable when cold . this should inrich your mixture an stop your pinging . Be sure too pull your 40 amp fuse before you start work an replace at finish time to retune your bike . Just an old solders thoughts . Bud, Valor in March 1968 on fire Base Harry 11th Calv.

2008 O2 sensors won't fit into 2011 O2 sensor bungs. 18mm vs 12mm.

Wiring/plug is different as well. 2008 is a 2 wire sensor and 2011 is a 4 wire sensor. Completely different plug.....
