I know there is a million topics like this one here I did a search already and didnt find the actual answer I was looking for. I have done a lot of reading on this but it seems everyone is asking for their 2 strokes and 100LL vs VP race gas. My question is will running 100LL affect my 08 YZ450F in a negative way? I live by an airport and can get fuel for about $1 a gallon more than the ethanol contained 91 pump gas I can get everywhere else. Is it worth it to not have the ethanol content? Do I need to add anything in the fuel to protect my engine?
