Interesting Steve that you also went back to the saddle chassis
I'm loving my KF - last week - even with 2 meetings old pins - coming put of the 90 degree astro corner (the one on the concrete section where you carry little speed around it as you are lining up for the big jump) - accelerating towards the big jump - I could get straight onto the gas out of the corner. At one point I was almost pulling wheelies along there as I was trying so hard to catch the leader - but it continued accelerating in a straight line!
