Glad you got them to fit Keefy, theres no way i could get the rear cover to go in from the back of bike, i'd removed all the pipework just like you, tank etc and even had rear brake resevoir off, the covers caught on the cam tensioners rollers no matter which way they went in.at one point i was contemplating taking rear exhaust manifold off and removing pipework, typing this I've just realised i've got the 57mm full system which may have reduced space
