Went on group ride yesterday to Philly for a cheesesteak. 17 bikes in all from Maryland and just outside Philly on I-95, big traffic jam and we all screech to a halt.

Outside temp about 95-96 degrees, stock 09 Ultra with about 8800 miles running AMSOIL.

Gas is 30% Exxon w/o ethenal and 70% WaWa with ethenal. Creeping along, stop/go and I start pinging. Other riders around me heard it also. No one else is pinging, just me.

Got to Tony Lukes and filled tank with a about a gal + of Exxon and let cool.

No problem getting out of town or on way home.

Should I have bore scope of cylinder walls? Was it just the crappy gas? One guy with oil cooler gauge said he was at 300 degrees. Comments please

 

Heat and a lean mixture will do it every time,do you have lowers on? The first thing I did when I bought my 09 was get the TTS tuner and a oil cooler.

 

Yes lowers were on but wide open.

 

I took my lowers off in May,I've tried removing the doors in them too that gives you a little more air but just removing the lowers works best for me.

 

There is a refinery, pretty sure it's Sunoco somewhere in that area of the country and every time I'm over there I have trouble with pinging. The fuel starts showing up about mid-PA and on down into Maryland. It's the only gas I have trouble with.
