Just had a garage clean out as there was tools and all sorts all over the floor so just had a full hours minting Sesh! Anyhow whilst inspecting the bike for general mingingness besides what appears to be soot and a good bit of it under the front belly pan just behind the front wheel ? Their was also a good smear of melted race boot over the top of the carbon yoshi this was easy to remove with a good rub of a wonder wipe I know how this has happened as coming home on Sunday down the motorway I altered my riding position "due to leg and arse ache" and must have flat footed it and the heal must have sat on the can no big deal I know but maybe if you had a stainless ?
Funny you should post this giv as when you pulled into hawes last weekend i did notice that your boot was almost touching the yoshi. strange how you notice these things
