So I have been seeing everywhere ON LOTS OF SITES the 07 R1 stock is 156.6 hp . Well I installed a BMC race filter, dropped a tooth in the front, and put the Graves cat-Eliminator exhaust. I took it to a HP shop a hour north of me and had it thrown on the dyno.... well good thing the cat-Eliminator brought me 10 HP THRU THE ENTIRE RANGE!!!! AND 6 POUNDS MORE TORQUE!!! but the dissapointing thing is its started at 146 and made it to 156... how is this possible? every site says 156.6 stock?!?!?!??!?!1 and I know this guy knows what he is doing... he doesnt show "fake" number like if u have the dyno in a sealed A/C room is will boost numbers and such.. and if you dyno a hot bike it will show better numbers....
