I've only ridden it about twenty miles since but i'm sure the brakes aren't as sharp as before.
Should I just bleed them anyway or is there something else gone wrong?
Some types of pads need a specific break-in. Try this:
Find a deserted piece of road (or a track) and get the bike up to 70 mph; use medium pressure to brake the bike down to 25 mph or so.. repeat 5 times in a row, fairly quickly to get heat in the rotors.. after a few more seconds, get the bike up to 90 mph and try braking moderately hard.. See if that helps
Another issue, could be with the rotors .. they will have a wear pattern in them from the previous pads and it can take a while for new pads to wear to match your old rotors.
