I was going to drive it back, but it was the coldest week of the year. The temperature was -15C. I was prepared for a sub zero ride and set out. I only got 15 minutes out when the motorcycles stopped. It blew the head gasket. I telephoned the dealer, he collected me and the bike and I took the train back to London.
He repaired the head gasket and delivered the bike to me a few weeks later.
