the slipper peg kimbrough spur gear combo...
worked a little for me. It was would slip but catch enough to work well. After 3 runs, it was gone and would slip under the slightest throttle. The plates are hitting some part of the plastic flanging still...or something. Im likely going to get a sanding disk and flatten each side of the spur a little more to see if that'll help.
Otherwise im at a loss. I may try the t3 slipper setup.
