Here is the dyno run for my '05 Thruxton. BC airbox removal, K & N filters, 42 pilots, 2.5 turns on the screws. Got a dynojet kit for Thruxton, no jets were even close but used the springs and adjustable needles. Now has dynojet 144 mains, needle on 2nd from bottom clip position. I should add the baseline run was with 42 pilots about 1 turn (very lean), stock needles no shims, and 140 mains.
