Kirk,
The motors are very, very even. I think it was Biland #1 Oral #2 Biland #3 oral #4. All of the motors are very strong and seem to have simular torque curves. These aren’t you “fathers motors” like the commercial said. You should hear them screaming into the braking zone. Amazing!
We never paid much attention to 4 strokes, love the Briggs classes but Ronnie and a few others seem to run them with success. We are now very interested in them. Excellent power delivery, low maintanence etc…
Hopefully if we do run these next year, we won’t have the “this track favors this and that track favors that motor” as much as we do in the 2-strokes.
We certainly aren’t giving up on 2-strokes and plan to keep running what we have, but are looking for good quality performance and low maintanece seat time next year and this might scratch the itch very nicely.
Rick
