.... of a bloke / shop or tinkerer that can convert the KPH speedo from a Yam LC to read MPH and also refurb the whole lot to mint.. new bezels, bushes etc
A few years ago I needed a Fireblade clock re-furbing and took it to a guy called Peter Bond in South London. His contact details can be found here: http://www.guagerepairs.com/
I found him really helpful, although he does / did get rather busy. He does switch-gear too if anyone needs those doing.
Good luck with getting it sorted...!
PS: IIRC, he can also do the conversion from KM to Miles too
