Sat down with the main kwaka Salesman back at Febuary 2010 & was also the Head of the Mechanic department with me, on signing up for my New ZX1400 I asked about the Slip-ons, they recomended just three exhaust companies only that would not "Void" the Manufaturers Warranty as Leo-vince was one of the 3 ! that's what I ordered with my 2010 ZX1400f that wasn't even on the floor, It was shipped from Victoria, the Mechanic said that would give me 6hp straight up ! Although I ended up getting a PCV installed on my ZX1400 Later by Lees Spot On (Dyno Tuner) did it for me! And one thing that Hub stated is CORRECT our fuel My Mates & I use is always 98 Octain, that's probably why then the USA Octain is to low for our Hyposenic Engine's Performance & their more prone to "backfiring" over their?
