Hi All,
I am Joe's "awkward customer" so thank you all for your comments, suggestions and help.
I had another go at installing the mod this evening and it went in really smoothly. I have no idea what I did wrong the first time, but something was obviously binding somewhere that I didn't spot. Perhaps doing it at the weekend helped rather than doing it after work when tired/hassled! 😆
I haven't ridden the bike since modding it yet, but just sitting on it feels like a more natural position - I think this will help a lot.
Joe - Thank you for your patience, and please accept my apologies for wasting your time.
Cheers,
Jon
