I see JMG is back with Honda for this years TT alongside Conrod. Which is a good team and will be riding for wins.
I also noted that JMG will be riding the endurance Superstock rounds, and in addition running his own team from "the back of his van". I think this is John's way of looking to the future, with as much experience as he has, particularly at the TT races, he would be in a good place to have his own team in the coming years.
I suspect he would need some entrepreneurial partnership, someone who could make the business side of things work. But for experience in racing at the TT there are few who could doubt his expertise and accumen.
He might be able to take a classic machine around the mountain course for a good few years yet, enjoy himself riding the circuit, but as a top flight Superbike rider in June, he has to be thinking he is in the twilight of his career and what better way to stay part of the dream!
I think there will be a McGuinness run race team at the TT within the next few years, and good luck to him I say
