Can I use 110 octane leaded racing gas in my YZ125 dirtbike?

Question

Im asking this because someone told me that I could. I dont plan on using it all the time because its to expensive and I am not getting any knock or pinging. I might run a tank full through see if it improves anything. If I do run a tank of this would I need to change the mix ratio? Right now Im running 30:1 mix ratio.

Answer 1

It wont do anything power wise to your bike unless you bike is built... in that case, you could only run race gas.  (110).  You might even feel less power from your bike  because there is less to burn off in that gas.

Answer 2

NO dont deffinitly dont switch back and fourt i wouldnt use it but if u wana keep to the 110. you will probly blow your engine a few times if u ride hard.

Answer 3

You can if you want to feel the piston go through the tank.

Do you really think a YZ needs any more kick? Buy a 250.

Answer 4

don't waste your money

next time ask a racing question
