It should come with a list of swear words to use while fitting it, but believe me, you will invent your own!
You will curse the maker, curse their mother, accuse them of outrageous things that may or may not be true but will seem true at the time. But just work with the piece and it WILL fit.... and nicely as well!
Instructions say to remove the mirrors but that is NOT NECESSARY.
Chroming is 1st class however, and changes the whole aspect of the bike. Make this your first bit of chrome!
Would give it 5 stars however the instructions are extremely poor. Once started, you are on your own......
