Wow, here's a concept, what if GG just has Yamaha handle not just the 4T powerplants for GG, but let them handle all of the tricky issues that has escaped GG management for the past decade and outsource their dealer network, parts inventory, marketing and warranty claims. It is so sad to watch GG destroy the momentum they had in the US market in the early 2000's and now talk of a comeback in the face of the worst financial climate since 1981-2. I was a huge GG supporter back in 2001-5, but after watching GGNA in Tampa foul up everything that a distributor is supposed to do, I'm just an interested bystander. It's like opening my monthly investment statements, I just can't bear to watch.
Oh, and I have a Yamaha WR450 in my garage and a GG 300, and my brother has a WR250F so I'd like to know how many of you that have posted on this thread have ridden both. My opinion? If you revalve the suspensions on the Yamahas - look out, they are really good, but they are still four strokes. In the right terrain, they are surprisingly fast and easy to ride.
Should Yamaha ever had made the decision to put a six speed tranny in their YZ250 two-stroke, it would have sounded the death nell for the current GG two strokes. Awesome power, easy to work on, tons of parts and aftermarket support and light weight, the YZ250 two stroke is a formidable platform.
