Default Pinging after trip

Just came back from a long trip, had to use 87 octane from some stations and hitting some big hills and basicly unload at 2800 rpm and above I'm getting some pinging. I generally always have my tunes on and or earplugs for long trips so I don't know how long its been happening but gotta get fixed up.
2016 CCT Drew Miller mufflers,
Loyd's air cleaner ,
1/4 turn throttle ring,
Loyd's timing wheel set at +4 ,
PCV & Auto tune,
ignition set at +2 above 2500 at 40%-80% then +4 at 100 % ,
have been using AutoTune for past 25000 km ( haven't accepted or looked at AT map since 17000 km )

I put on about 4000km with the lower octane gas ( most times )
What I'm wondering is should I try running a couple tanks of 91 octane or higher through before adjusting the ignition timing in the map and see what happens?
Thanks

If it doesn't ping with higher octane gas one option would be to carry an octane booster while out on the road for those times you have to go with 87. I'm sure you have room for a couple bottles.

A RICZ laydown license plate bracket will stop that pinging, improve HP & torque, and make your bike an irresistible chick magnet. Click the link in my sig. Also try shifting above 3K rpms.

Cure that ugly stand up license plate with the cheapest and best laydown bracket. Click this:

Ok so what your saying is run a tank through first before trying any changes.
I'm just hoping I did no severe damage.

If you holed a piston you would know it.

I hate to ask, does it take much to hole a piston?

Yes. Because the sounds you are hearing are rapid explosions occurring in the combustion chambers, instead of a slower burn that's supposed to happen. The higher the octane, the slower the burn. Using regular when premium is required ignites too fast, causing explosions/pinging and can burn pistons and valves.
Because I am always suspicious of the gas I get on the road, especially in small towns, I like to keep my ears available to hear the sounds the bike makes, like tires of the pavement, the engine and for pinging. So no music, except that emanating from the pipes.

I think I would. If you're all good with better gas I think you'll be good with packing octane booster for those times you have to run regular.

I've been concerned about getting some pinging myself. My 13 is at +4 and I usually run mid grade. Now that we're seeing hotter temps I was concerned it may start but so far so good. Fingers crossed!

Its the noise of the flame front hitting the piston before it reaches top dead centre.
Its like a big hammer hitting your pistons and tryna force em back down before they get to the top.
Either use better fuel or retard your timing enough to stop it.
