looking for a street tracker pic from the UK

[bluejean]

There is a builder from the UK who built a Yamaha xs650 board tracker. It has a girder front end from a old bsa, the gas tank looks like a narrowed xs650 tank that is pin stripped, a chrome shot gun exhaust, the seat pan look like a old cafe style, and the bike is all black. Can someone tell me who the builder is or have any pic of the bike ? I can find any online.Thank You!
