Loz, Gary at Automotive & Marine Trimming did the seat - he is in Addlestone, Surrey 01932 845858. He made the base & covered it for Alan, as the tail piece Al had, didnt have a seat base at all.
As to borrowing till Nov 07!
Regret you cant mate - it needs to be at the NEC for 10 days or so THIS Nov! (yet another plug for AK, as he has been asked to bring it up to go on the Streetfighter magazine stand).
Any w/end date before then is ok - but caution - I'll borrow your bike & follow you!:P
