The saga continues,
the 961 street has returned from the dealers after nearly 3 weeks, guess what. The first ride out and the problem remains. It ran fairly roughly until warm and then wouldn’t slow down until a prompt from the brakes . At the first stop after 25miles it wouldn’t tick over at anything less than 3000rpm. Turn the ignition off, start the bike up and it ran perfectly well for the rest of the run!!!!
Back to the dealers I guess.
