Ima bolt me on a set of SuperTrapp slip-ons and a "Tuner kit" and kick everybody's ass with 160+hp at the rear wheel!! I saw it on Ebay, so it must be true.... :biglaugh:

We all should bombard that guy with alot questions and interest on bike :rofl_200:

i have an aprilia rsv4 and cylinder firing order is left rear left front right rear right front same as ducati desmosedici, honda rc30 and rc45 and all of them connect the 2 rear cylinders together and the 2 fronts together, that being said i know vmax numbering is left rear right rear left front right front so its odd ball compared to these other v4's, over racing conects vmax headers the same as the above mentioned and hmf and ufo do it like they do it, it seems to me that kerker is the right way for a 4-2-1 on vmax?? my ufo 4-2 with hmf cans/stg7 made 127hp on hmf's dyno
