can you run leaded gas in HD motors? Example :Sunoco 113 race fuel, its from the pump but it is leaded, safe to run or not?

 

Leaded fuel may screw with your O2 sensors. But if you don't have the compression that requires that high of octane, why try and use it?

 

i have/am going to have in 2days 11:1 compression

 

PING PING, Good luck, you won't find that fuel on every corner and it kinda limits the cruisin ability. I wouldn't go that high unless I was building a race bike.

 

If your bike is designed to run on 91 then anything above is a waste. Just like why would you put 91 in a stock car that runs fine on 87. Besides all the new fuel injection is adaptive and changing fuel grades and even brands in certain circumstances can cause driveability problems. It's best to run the same octane and brand of gas consistantly to get the best performance and economy.

 

If it were me I would try to run the high test first, then IF you get the pinging add some octane boost. I would not run leaded gas.

 

The leaded fuel will conciderably shorten the life of your O2 sensors if your running them. Deppending on the injectors it could clog them too. That and leaded fuel isn't street legal due to emissions

 

What other motor work are you having done?

and

What type of riding are you going to be doing with this bike?

 

Unless you're drag racing I wouldn't do the compression or the fuel. Have you been watching the fast and the furious? Need more NOS?

 

When you go on a trip, where are you going to get gas for that 11:1 engine?
