Thanks guys for the help but sourced one from a car spares supplier that my mate uses, he runs his own garage.
Quoted the Valeo number of the starter and he had one each side of that number on the shelf. Told him afterwards that it was for a motorbike but he had already phoned back saying he could supply one next day for £105 plus vat.
Thats a brand spanker Valeo unit exchange..... result.
Anybody need one let me know and if you get my mate a drink will sort it..
