Good ride today. Glad I dropped mine instead of yours!!! Thought I'd add an outside, somewhat objective opinion here wrt the swap. The opinion is this: I need my motor to explode so I can justify the swap.
Nice, flat torque curve, good compression braking, and the power is there regardless of gear for the most part. And that's with no intake tract or airbox to speak of. With a proper intake and a power commander this thing will be a beast. My DR is fairly quick I think, with a good jetting in a tuned carb, pre-96 motor, open airbox and the like, and it was all I could do to keep my headlight in the mirrors on those short freeway blasts. We hit 80+ in short order...that sixth gear is a huge plus, if not the biggest one. Plus, it's pretty sweet that the motor didn't fall out on the first set of washboards. So. As a guy with little dirt bike experience past an old, overweight DR650, I can say that this is a pretty enviable set-up. Whatever that's worth.
