Engine layout and innards!
We all know the basics, so I won't bore you by repeating them here. If I think of something interesting, I'll add it later.
In the meantime, here are some pics of an RG500 engine next to an RZ500 engine, as well as lots of pix of a clean, disassembled RG500 engine. BTW, be warned that sometimes I may use the term "motor" insted of engine. I'm from the midwest and that's part of the vernacular, so you'll just have to be understanding!
Here are some pics of the XR40 engine vs the XR45 (XR45 has SAEC-style exhaust valves)
