I have an 18 mill twister that's at 79 mm bore and is pretty fresh. Reason I say fresh is the guy I got it from I cant remember if he said it was fresh or had a few passes on it. Anyways its stock cases, with the bottom mounts up graded, topend, with vf3's and rubber intakes that had nozzles in them. twister 18 mill crank, with a set of shearer pipes, nothing fancy, 1 out each side painted black. I would like to if theres anybody out there that has mybe cases with topend , with or without a crank that they would be interested trading. Ill hae pics up later.
