Maxima Hi-Test Octane Booster 5 5 2 2
Well, what can i say... I put this in my tank not expecting much, it was recommended when i bought the bike and ive been putting it off, finally picked this stuff up and wow, i could feel the difference right from first gear, it didnt struggle as much and it pulled me longer and harder then before. Absolutely pick this up, you will not regret it, i used this in my 1985 Kawasaki Gpz 750. May 15, 2015
