My friend has an 02 954, Arata full system, PCIII and flapper removed. He hit 151 hp with a custom map this weekend. I have the same bike, same year with a Hindle F/S and PCIIIr with the K9 map and I am at 142 hp from the same dyno. Does the Arata make that much more hp then a Hindle or is just bike to bike difference? I have 11000 miles on mine and he has 23500 miles on his.
