Hi Gareth, I haven't looked anywhere for the info yet. Starting has improved but it still spins for what seems an age before firing up despite plugs, leads, coil packs, up-rated starter, air filter.

See if you can get hold of a guy called Jaydee Gerry. He is a bit of a wizard with anything rotary, but equally, elusive. Your best bet may be to go through Paul @ Whifbitz and see if they can either do it or get Jaydee in (He works closely with Paul on rotary stuff)
Whifbitz are near Enfield if that helps
