BW - You MIGHT able to answer this, but may be irrelevant due to us living in different countries. When you lock/safety wired you bike were you required to wire every single nut and stud that bolts the engine cases together? Also, when doing this, you drill thru the nut AND stud, correct? Curious as this is officially my first race vehicle build and new to having to use safety wire. I'm thinking I'm going to need a few new drill bits to accomplish this task.

Hi Scottie,
I drill through just the flats on the nuts or bolt heads - usually in through one flat and out through the one next to it. A drill of about 1.5 mm works well for me and I start by drilling straight in at 90 degrees to the flat and tilt the drill once I have gone in by about 1 mm, so that the drill is pointing at where I want it to come out and that is the job done. It is just as easy to do this job free hand with a pistol drill and a vice, as it is to use a pillar drill, I have found.
The only parts we have to secure are things like drain plugs, the screw in oil strainer plugs, rocker feed unions, oil filter cap nut [350 only for us], the spin on oil filter element on the 500 has a large 'Jubilee' type clip around it, with lockwire going through it and onto a nearby mounting stud, primary cover nuts - even on the dry clutch 500 and the gearbox fill and drain plugs. There may be one or two more that I have missed here, but that's about it in general.
Don't forget to trim and tidy any stray ends of any lockwire you use and tuck them in out of the way - scrutineers really hate getting cuts from it, when feeling around under an engine, as I have witnessed on occasion, though not from our machines, I hasten to add
