My bike starts perfect and idles perfect, measured the exhaust temperatures on the manifold pipes on idle and the temps on both sides go up at same rate. On bigger throttle openings, say quarter throttle up it also feels perfect. Just above idle the engine runs rough, if I open the throttle very slightly the bike wants to stall then revs up. Ive set/ synchronised the throttle cables - they were not perfect but does not make a difference. On normal to hooligan riding this wont bother but technical and slow riding this is very annoying. What can I check?
