Seems to run well everywhere, i trail rode it a little bit lol, and it pulled hard everywhere. Also raced some of the "other guys" port jobs and cleaned up house lol. Its a good all around bike and i like it alot, not sure how much of it can be credited to the 12 port over a traditional port job, but it runs really well all over. Also many have said they are hard to tune, but i havnt had any problems so far besides that it likes fuel, and i am in no way a expeirenced tuner, i know what everything is and what it does, but new to tuning these 12 ports, and its been a walk in the park.
Not saying anything bad about the other guys either, just sayin i kicked some ace which made me feel pretty good!
