Sorry, I thought I had replied last week but it would seem that once again my iPad has let me down.
I suggest you give Brian Giles a call on 01892 823514 or 07850 438404. Email brian-bgm@fsmail.net
He is based in Pembury which is just off the A21 near Tunbridge Wells. He did a lot of work on my K1300GT earlier this year and was roughly half the price BMW wanted.
Good luck!!
