I'm not gone.. Still have to care for the good 'ol F-12x.
I will say this... The 300x burns a tonne of fuel. We did a ride from Discovery Bay to Sacramento and back this weekend, a 120 mile round trip, with a bunch of people while I was still being real easy breaking her in. I filled up the 300x a total of about 3 times, while the honda only took one. I brought a 5 gallon jug of 100 octane with me to deal with the lack of 91 on the water, used that during my second fill up, only to have to fill up again with 87 and be the slowest one home to stay off the boost with the "SLO" key.
