    Great ad! I hope Yami comes out with some big, exciting changes. IMO, they had the most revolutionary gen 1 racing 4 strokes (of recent era). Everyone seemed to catch up with Honda taking a big lead in recent years (look at MX starting gates for proof). I think they have the internal resources to engineer some crazy new stuff that should help get them back to the top again. Well, they should at least be winning with Stewart regardless of what they have him on.
