Hi Guys! Just finished a few little mods to improve the overall performance and ridability of my 1100 Evo. I have an SC project Carbon exhaust and air filter with the Ecu flashed to suit, this disables the lambda sensors and the little valve on the exhaust. 14T front sprocket. Let me tell you it has made the world of difference! Lovely pick up, more friendly at lower speeds and just feels more monster like! Highly recommend these few little tweeks
