Think it's been very well looked after. The guy i bought it off covered very few miles over the 5 years he owned it, he was a proper RS nut as well, had a minty Series 1 and a 14,000 mile from new Mexico (rep i think, but near concours) so can't imagine him neglecting it. His mate owned it before him and was pretty much the same....

Im using Valvoline 20/50 Racing oil.

If it only needs a freshen up, what sort of cost is it, inc labour? That is the main thing worrying me at the moment!!!
