I'm trying to tune my stock MR-12 for the backstraight at a huge track (KZ). My V-One RR runs out of gear about 2/3 of the way down the backstraight, and I'm geared up as high as I can go. Should I just start richening the high end needle, and then readjust the bottom? FYI I was using an Assoc. GT pipe with a Kyosho header. Thanks for any help!
