They can check the timing with a gun, once they remove the belt covers.alot of money if its not though. Ive just pm'd danny to see if he knew of another way to check other than just doing the belts again.
RS Murray or RS Tuning is nearer to me but not sure on their prices

RS tuning don't do belts Pauls dad is the owned of RS murray but I'm not sure on the price either. Plus I trust Birchdown (Not saying Pauls dad can't do it I just preferred the idea of birchdown)
