Looking a bit more positive now, thanks guys.
Tunnel shouldn't be an issue, no intention of trying to use it. In the unlikely event I qualify to race world cups this season I can use the ferry. Also, I never use multi-storeys so unlikely to be a parking issue, but worth knowing just in case.
It runs on petrol and LPG. No probs getting LPG where I live but I travel to north Scotland and Snowdonia regularly and it's not always easy to get there.
5thElephant, thanks for advice about the manifold and the valve. Also, I didn't know about them running hotter, seems to be a consensus about that. Think it be worth fitting bigger fans for the radiator? Or would the radiator have ben upgraded as part of the installation?
Cheers
Andy
