Just the one near the top coil mount point I believe, like all the other NSR's.
And you maybe right in thinking (like the V4 400's you know so well) it's a potential weak point. I'm old enough to remember the idea that you should run a few extra earth's on an NC30/35 and I did so on my first one, hopefuly this little diversion into 4t talk will be overlooked by Mr Grant as it's me
