i agree about doing your bike test, im 18 and passed my A2 license in June this year, best thing i ever done, ditched my '09 RS125 for an '06 Z750. but i was very confident, and thats the key to passing your test ,confidence. get out and practice the stuff you dislike, then get it booked up

but in reply to your question, just pop in and tell them the bolts worked loose, (im assuming this is swindons "blade honda" if so) mike shouldnt have a problem with fitting a new one
