I look at the Phazer engine in a blast as a compliment to the line up, rather than the same damn thing with blue stickers. Why not appeal to the folks that truly want a 4-stroke. If they want 2-stroke, go place your order today at the AC dealer. Hell, they have blue!! And wraps are cheap.
When we owned both the SXR 500 and the Phazer FX 500, these were too hard to compare, as the chassis were so different. But the performance of the two engines were night and day. The SXR could get up to similar speed, but the phazer's torque from 0-60 was way better. And I can only assume that if that engine were in a blast chassis, it would be a hoot! Weight would be a non issue, as the power would be so much more, that it would feel light. And for those that really want it to be light, they will stay with the one-lung 400cc.
This is the same explanation why some guys will like the 800cc CTEC2 and others like the 998T in the nearly same chassis. They will want one or the other for different reasons and they compliment each other in the lineup. That's the right way to do it. It's really to the point that AC could produce the 2-stroke and Yamaha stick to the 4-stroke and life would be grand.
I know there are a ton of Yamaha fans here, that really had wished that the Phazer was announced in a more traditional chassis. And even more begged to have it dropped into a ProCross chassis later on as a starter sled. I truly believe that if the Blast chassis was co-developed to accept either engine, that they have a winner on board. And the blast chassis is a better size for that 85hp Phazer Engine, than the ProCross.
If it doesn't come, I see the next custom sled build.
