Hey all! I'm wondering what octane you guys are running on your big bore engines. I searched around on the web but couldn't really find anything solid. I have a 187cc engine

if you have a high compression motor you would be better to run the highest octane gas to prevent ignition knock if you dont have that problem then you can run the reg gas
