I though I wanted a cub, turns out that I don't. I ride trails and horseshoe drag, these are not for me. I got 68mm stock stroke cub cylinders with a clean up port and a 115mm long rod crank. I also have two sets of used pistons, (usuable), and two sets of 20cc domes. I'm looking for a +4 crank and stock cylinders with no porting and stock bore.
