Is it an after market exhaist. Could just need setting up on a dyno if so.
Check wheels are balanced.
Also do you have in bar ends?

I would take Mikiboy's advice. After market exhaust. Check if you have 4 pipes going into 2, then into 2 - that is the correct configuration. If you have 4 pipes that go straight into 1 then that is a cheapo after-market exhaust and you will get a flat spot when you try to accelerate which will pick up after a second or two. Only solution is a new exhaust.
Central Line in rush hour or the A40 by bike? - well Duh!
