Anyone on here own a black Sappy thats been bombing around Mottingham the last week?

It's got what look like 17" multispokes and a decent sounding dump valve. Can't tell much more about it as its usually doing about 100 mph as it bombs up/down Mottingham Road! Quite a bit of blue smoke though!

If its anyone on here then what mods / power has it got? Must me someone local to Mottingham as it seems to go up and down all day and evening every 10 mins, two or three up, and it gets thrashed. Never seen it driving slowly . Its a testament to the durability of the cossie engine!
