I thought something was wrong with my bike still because of all the enging noise. And when I wasn't being cheap on gas, I switched to supremeand "WA-LA"... "Presto chango".... No PINGING!!

Maybe that's why I haven't changed my "Nu B" name!?! [:@]

 

I think supreme is what you should be running anyway.

Locally the octanes are as follows:
regular: 87
Plus: 89
Supreme/Pemium: 93

The octanes may vary some, but probably not by much.
This means premium/supreme is our only choice.
The manual on the '07 tourers lists a 91 octane minimum.

For those previously unaware and having noise issues, could this be the cause?

 

I agree with Blackmouth I think supreme is what the Mo Co recommends. I have never used anything below 93 octane myself.

 

High Octane for sure!

 

Best we can get here is 91. Bike runs great.

 

I"m pretty sure it says in the manual for my '05 to use supreme, and I know Bruce, the HD salesman told me to use supreme.

I have only used supreme except when I was stuck at a gas station without 90-something octane and not enough gas to move on. The bike ran like poo.

A 76 station near my parents' house had racing fuel, over 100 octane. Every once in a while, I'd run my car down to fumes and put in a few gallons of the racing fuel (It was OUTRAGEOUSLY expensive, like $3/gallon), and the car ran like new. It was a 20 year old Oldsmobile with over 100k mi.

 

It good you found out what was causing the pinging.You will probably find you will get better milage out of high test than regular grades.

 

93 is what the MoCo recommends. I would call your salesman back and bitch at him for not telling you that.

 

I always run the mid grade and no problems at all gas mileage stays the same only thing I notice is if you don't shift when you should up hill around corners you can get a little ping. have even accidently put in reg and saw no diff. although I did ride a little easier.

 

Must be nice. In Alaska, I haven't found anything higher than 90 octane.[sm=smiley21.gif]
