I recently bought a banshee and it came with a lot of spare parts in a box. I started looking at the cool head first it seems to be a trinity looking head has the IV on the top of it. But yet it's only a two piece head no removable domes or any spots for orings anywhere. How would u seal the head case bond? Then the cylinders are really weird they are resleeved and are 71 bore and 4mm stroke. The spacer plate is weld to the top of the cylinders then holes drilled in it to let the coolant through. Also they have welded up the outsides of the cylinders by the transfers and the rear outter cylinder base nuts the studs are longer on the cases also plus the nut location was raised up. The pistons and cylinders seem to be in usable shape but the 4mm crank had a bad bearing also it is bent when I spun it in the cases. Is it worth rebuilding the crank and messing with the topend u think?
