Thanks for the warm welcome Andy. I don't think you should worry about treading on toes. The more information that's available and the easier it is to find, the better it will be for the folks that own one or are considering owning one.

The 400 was probably the most compromised of all of Honda's race rep 2 strokes, yet is still a great little bike. Quite possibly the worst sounding stroker on the planet, but I love 'em just the same. If I can help anybody out, I'm happy to. If I can't, I can probably point them in the direction of someone who can.
