U have to underatnd... most of these top flight bikes make 80 or 90 foot pounds of torque. They make alllll those 200HP via lots of rpms. Once u get over the metal aspect of winding it out, and hanging it WFO...... the game becomes more clear. around 350HP is usable on the street. Even with a mild stretch to deal with the 200foot pounds of torque and bump it up to 400HP, im still figuring it out. SOMETIMES it does a wheelie and the gas tank hits me unexpectedly in the center of the chest. though. I think i got the JRI shock figured out. The torque becomes tough to deal with.The infection is spreading.
