Robomog,
Thanks for the advice. Not knowing how old the tyres are, and the fact that only 500 miles were done by the previous owner in the last four years makes an update a more of a priority than I thought. Mmm, that's four tyres and a new Mulfab radiator to find the money for...

Jeremy,
Hello!. Good to meet you and your wife also. The Bromyard FoS was a good day, and there is plenty of Youtube footage already loaded (some very fast parade laps!). This morning I also found a photographer flogging his pictures of the event if you are in there.
Thank you for the vote on Vreidstein T-Tracs. They seem to be a reasonable bargain on the net; I just need someone willing to fit and balance if necessary...

What does anyone think about balancing? There seems to be some division on this. I am currently balanced on wires.
