Bill is an interesting character. Very say-it-as-it-is and colourful character. Really great fun. He surely knows his stuff as far as building race bikes (he does not like / touch road bikes I believe) and especially the pure-Corse machinery. He is an helpful resource as well when dealing with RS / Corse needs and I guess his shed would be a goldmine to most of us with the rarest of RS bits gathering dust.
That said, if your need is urgent, Bill works with race teams and customers that spend thousands on high grade machinery. So your needs are likely to be at the bottom of the pile if you don't belong to this category. I am still waiting for an RS water pipe that he was supposed to have a lot made up. Got one made up by Jeff at GTEC in the end who really went over and beyond to sort me out.
he is rebuilding my 1995 916 motor at the moment thanks to an early retirment from the main bearings. why not give him a call and ask him for his opinion on that particular bike ?
you tried mailing service@wlracing.com ? i know the lad who works up there with him hasnt been in, i spoke to him yesterday and he had a new blackberry from me after his got damaged.
