All the gears shown earlier are inside the this case. Bob weight and kick start gear / spring etc. Its all ended up a bit wider than I expected but too bad just needs to run now. This is the 360 with mk2 injection. Although this case look bulky it all machined from blocks of 6061, thin, so it all weighs bugger all.
Kick start is machined from a piece of 7075 block. Worked out nice in the end.
