I, like others made up my tool kit from home tools by looking at Harley book tool kit and seeing what they sell. I use an old hand gun soft bag to contain the tools; cost to me ---nothing....have not needed anything yet.

 

Besides all the tools I carry (both metric and standard)... A slew of things like tie straps... etc. etc. etc...

I also have a small air compressor (great for the guy who shows up late and has a low tire)... it is both battery operated and plugs into my cigarette lighter... it has a light with emergency flashers built in... I once used the compressor on a completly flat tire... aired it up and rode it to the shop before it went flat again... The compressor is inexpensive and can be purchased at Walmart...

I also have a siphon kit and empty plastic water bottle to transfer gas from my big hog to smaller bikes that run out of gas...

 

I just got my toolkit from windzone it was under $100 and tools are guarented for life.
