my bike has just had its anunal service, while it was in asked the dealer (not the dealer i bought the bike off) to look at the front of the engine as it has a unpainted area, was told by two mechanics there that they are all like that, so they can get the bolt out. would like to know if what they are saying is true or are they pulling the wool (have lots of it here in wales) over my eyes. have atached some images.
