About this detail of the Tiger
The kit provides the two mufflers at the rear, each one made of 6 parts. At the top is the muffler guard cover, part C1, supported on 5 posts.
The correct alignment of the guard is like this. One of the bolt heads is always central at the rear. Unfortunately the locating holes in part P11 are not aligned exactly like this. You should remove the pins from the support posts and glue the cover in the correct alignment, ignoring the holes.
