Hawk and higher octane fuel

LunaTech · 03-02-2017, 02:39 PM

Just wondering why it is recommend to run at least 90 octane fuel in our Hawks. From what I know about the octane rating is higher compression engines need the higher octane rating and the rule of thumb is if you can hear a knock or chatter (spark knock) then run the higher octane fuels. Also it's been said that the Hawk was designed to run in Africa, Spain and other countries and was to be a work horse, so to speak, with little maintenance needed. Now I'm not well traveled but I am wondering how accessible higher octane fuel is in these countries. I've been running 87 octane in my Hawk for the last couple tanks and haven't noticed any difference in the way it runs or sounds. I want my Hawk to last many years because it's just plain fun to ride and was wondering what everyone's thought is on this. Weigh in and let me/us know your thoughts. I know there people on here much more knowledgeable that I am and maybe I'm just thinking wrong.
