We analyse the production and propagation of pions and kaons in heavy-ion reactions from 0.8 -- 1.8~A⋅GeV within a coupled channel transport approach including the kaon production channels BB → K+YN, πB→ K+Y, BB → NN K K, πB→ N KK, K+B→ K+B and ππ→ K K. Assuming the hyperon selfenergy to be 2/3 of the nucleon selfenergy we find that all inclusive experimental K+ spectra at SIS energies can be reproduced reasonably well without any selfenergies for the kaons although a slightly repulsive kaon potential cannot be excluded by the present data on kaon spectra and flow.
