This threads been making me lust over the idea of a billet 1100cc (CNC'd) Caracarol Banshee twin cylinder motor, and other trick big bore 2T motors.
But I just fired up my 421cc twin this evening for the first time and I remembered why the 421Cub motor is so good.
Its just pure bang for buck reliability.
I dont think you can build a reliable pump gas 85hp two stroker for less, and have the ability to squeeze out 100hp down the track with big carbs, high compression and methanol.
Going to have some good fun on the 1/4 mile this weekend hopefully
