ORP is a pretty awesome track - did a double header there myself around 7 years ago. It's like a roller coaster when ran clockwise (it can be ran bi-directionally).
As for the tires:
- Have Journo's ran the OEM Maxxis tires on track - yes. Keep in mind these are typically VERY experienced riders/ex-racers who have typically ran thousands of laps on track so their pace on mediocre tires can be quite impressive while still maintaining a high margin for error. Sadly that doesn't usually translate to Beginner/Intermediate level TD riders who need all the help they can get as their throttle inputs aren't as smooth as they can be, quite often their lean angle is higher than needs to be, and their setup or understanding of the bikes limit's isn't as refined as it will be once they progress.
Look at Race School Instructors as a prime example - they run high end street tires like Dunlop Q3/Q4's or Pielli SC's while teaching Club racers and are doing so on the pointy end of the Advanced group pace or faster and almost never have an issue with grip while riders in Beginner have slicks and tire warmers yet lowside/highside on average roughly 20-30 times more often.
My rule of thumb is proper high end rubber is cheap insurance at the track. Dunlop Q3+, Q4, Pirelli Supercorsa, Metzeler M7's, Bridgestone S22's, etc... will all be a huge upgrade over your Maxxis OEM tires and none of those require tire warmers, just a lap or two and they offer amazing levels of grip.
As for your video - if there are Instructors at ORP have them work with you on RPM Management and upshifting/downshifting - those two items you can have an "a-ha" moment with after you see the difference they make. You are vastly underutilizing your bikes ability and the upshifts are unsettling the bike - sort those two out and that alone will increase your margin of error and drop a LOT of time around ORP.
My ambition outweighed my talent.
