It's 13mm, anyway!
As I said, the NSR is a metric bike, so measure it in metric. 0.3mm doesn't sound like much, but it can mean the difference between 65hp and zero when the pistons melt if used in the wrong place!
There are also posts, with pictures and diagrams, in the archives... a search for "float" returns two excellent threads in the results on page 2 (one at the top, one at the bottom), amongst many others.
Besides... you're a Brit... you're supposed to be adaptable! If you were American you'd have an excuse!
