My observations from running a KA (my first experience with any of these “new” 100 air-cooled engines) at Rok the Rio…
I ran Masters. The top 5 were all on the KA, and by the end of the weekend, we had created a bit of a gap to the VLR’s. Now, to be perfectly honest, I have NO idea if that came down to driver / chassis or engine. What I do know is that early in the weekend, we were closer and I wouldn’t have known who was running what, but (personally) as we refined the chassis and I got better behind the wheel, I got faster and faster. Also, the top-5 all had more “team support”, while the VLR’s tended to be smaller true “privateer” efforts. My gut tells me that they could have run together, but because the KA is a “more tested” package, most people were on the KA.
In the Senior class, again, most of the karts were running the KA. BUT, the guy who led most of the final was on a VLR. So, I’d say that the VLR is certainly capable.
I believe that as time passes and more people become familiar with the VLR, that you’ll see a pretty even split between the 2.
At this point, my only question is how the IM engine will fit into the mix.
