a cure from the '70's try getting a misting spray bottle with water in it., warm the engine up then mist into the carb while rapping the eng. this will loosen any carbon on the piston tops, but then go fo a long 75-100 mile ride to expell the carbon out the exhaust.back then they made a misting kit to use on auto engines,
oh!! in case you think this is junk science. the old recip engine had this, ie they would taxi thur a fire hose spray, then take off.

Before you go back to the dealer. Run a can of seafoam or techron through the throttle body while keeping the engine running. Put a spray pump nozzle down in the can and run it through the top engine. Next, go by the dealer and pick up a new set of plugs. Get the se plugs. They make them two ways, one for stock engines, and one for high compression engines. Get the set for high compression. Now that you've got the cylinders clean, and a slightly cooler plug, go for a test ride. If your ping is gone, you've solved your problem. I run cleaner through mine at every oil change. If I miss one, I start to get ping. Today's gas sucks. The byproducts of burning ethanol blended fuel is more carbon. Give it a try, for 30 bucks, it's money well spent.

Unfortunately, competence is not one of my competencies. But if I had to offer, it's definitely the tune. Get that right and your issues will likely go away. Consider possibly a new tuning device that puts the control of the tune into your hands and not that of the dealer. Otherwise the dealer will continue to jerk your chicken.

Your dealer probably used 009SAR002 base map for your bike. It's the correct map for the 103 stage 3 but it's on the emission friendly side.
A couple of minutes tweaking the cruise range would rid you of your problems.
If you have cables and a tuning disk. I could help you out.
PM me if you want help.

My 2010 EG Limited has a SE Stage III. No head work, SE air cleaner, V&H Exhaust. Stage III is basically 10.5 to 1 forged pistons and 259e cams. SEST.
Work done by local Harley dealer, it was not dyno'd. The motorcycle had about 15,000 miles on it when the work was done. Has run great with no problems till now, 30,000 miles. This year as the weather got hot it has started pinging pretty bad. Dealer set the timing back a couple of degrees and it ran terrible but no pinging. They put it back to where it had been and it runs great but the pinging is back. It is scheduled to go to the dealer next week but was wondering if anyone else may have had a similar issue and found a cure? I use the highest octane gas I can buy. Usually 91 or 93 it makes no difference in the pinging. What would be the cause for it to run fine for 15,000 miles and now this problem? Thanks for your help.

Send me a PM with your email and I will send it to you. I would give you a phone number but we are camping near Bryson City and no signal. Do have wifi. Not sending the Stage 4 map but a modified version of the one for the stage III. If it isn't a super tuner it won't be compatible. It says on the front of the vci. I don't think a street tuner would get outside the emissions range far enough.

If you have a few bucks to spare you might want to try one of these or something similar instead of R&R the heads for inspection. http://www.harborfreight.com/digital...era-67979.html

The problem is right there in the OP...."it was not dyno'd".
Massive changes to airflow were made with nothing more than a dealer's canned map. That's a recipe for disaster, compounded by the dealer simply removing timing. Not enough fuel can cause detonation as well, which is why getting the VE tables right is crucial before you start messing with timing adjustments.
That's a good combination of parts that should make the bike run great. It's running like *** because the ECM hasn't been set up for those components.

Pinging finally cured. Dealer found that the the fuel filter was dirty. Then they put it on the dyno twice..... but could not get it right. They retarded the timing twice and it ran terrible. I did not want to have it dyno'd again but felt that I had no other choice. I took it to Skip's Cycles in Winchester, Va. They had it about two hours and it runs better then ever. Cooler and no pinging. 97 hp and 107 tq. Gas mileage improved also. Avg 43mpg. Thanks for your suggestions. A good dyno man can work wonders.
