Race gas lowers performance????!!!!
#11
race gas is amazing in carb'd bikes!! your bike should run low 10's all day with the parts you have on it if its mapped right.. at least my 06' did with just a slipon/filter/sprockets and mapped ran 10.6's consistently but i used to go every week for like 2 months. its just practice that'll get you faster, a city streets not gonna help anything dude u need to be at the track more than once a year to see any kinda improvement (not tryn to sound like a dick by any means btw) lol, have your buddy film a couple of your runs and watchem to see what your doing wrong, or right for that matter so you can get faster.

Higher octane raises the flash point. Increasing octane content is similar to pulling timing. It makes the flame front begin later. Our bikes are tuned for the timing of a 93 octane flame front, which is much earlier and at a more advantageous point in the stroke of the piston. With 103 combustion is happening at a later, less than ideal point in time.
You could've gone to a hotter plug it probably would've ran faster than stock.

i have to say one thing that i have found to be true,,,,,i use 89 octane exclusively in my bike,,,,but every once in a while i will use 91 octane,,,but then go back to the power i feel and crispness of throttle response on the 89 octane,,,,i thought it was me,,but i know my senses tell me otherwise,,,,,to me,,,87 octane lots of attack on the throttle but noisy engine,,,,,91 octane lots of lag,,,not as much power,,,,,,,,89 octane perfect,

To agree with what others have said, if you dont up the compression and advance the timing or remap on an efi bike then you're wasting your time with race fuel. Later and longer burn with high octane so if everything isn't set up right it will kill performance. Go as low octane as possible without detonation and you cant go wrong. Cheaper too.

As an DSM/Evo/STi tuner, I can tell you that race gas has advantages only IF there is a problem with the mapping on 93 octane, (for instance) or if its custom tuned for it. If you're tuned fine on 93octane and you put in race gas, technically it should do nothing for you except empty your wallet .
