Just had my Diavel serviced - a few issues with it have been resolved. But it has come back - and low rev running is a bit rubbish. It is like it needs choke / choke has been left on - depending on how hot the bike is. When it is at lows revs from cold it is snatch you, almost misfiring. Once the engine is warm, anything below 3 k seems again that it is misfiring / rough running. TBH i have been riding other stuff in preference - is this how they are and i have just forgotten, or do i need to talk with the dealer?
