I've had mine in for a few days.
I initially didn't dremel out the plate. Bad move. It was hitting the plate when in first and second. Not a lot, but enough to be annoying.
So today I dremeled out a ~ 1" x 1/8" notch and put everything back together. Much better!
Feels just like stock, just a shorter throw. My drivetrain feels really good now with this, the Kartboy bushings, and Group N tranny and engine mounts.
