Smelling rich..

Hi all. Getting the sv ready for spring / summer rides. Having started my sv 650s 2003 and letting her tic over she smells rich. Then taken her out for a good blast and on return she does not smell rich.. Oil/airfilter/oil filter change done. Bike has 9908 miles and less than 100 miles since service. She has a A2 limiter on the injectors but apart from that she is totaly standard. PS. this is my first sv. Also just fitting a SV 650 belly pan.
