hi every one. im from south africa riding a 990 superduke-acropovic pipes, full carbon fiber kit.the engine is very noisy as low rev torque, but at high rpm 4000 up its okay. alsow had a starter torque limiter problem- making the klack sound on starting attempts-fixt it myself.the engine noise sounds like a big end or small end bearing but it could be the clutch box or gearbox-any one having the same problem? the bike is going like a boeing!
