Siebenrock 1000cc Replacement Piston/Cylinder kit for 77-80 models

This kit is for bikes that are already 1000cc 1977-1980, to be used with 1000cc cylinders heads. Kit includes new Nikasil cylinders with stainless steel pushrod tubes, lightweight 1000cc 9.5:1 1000cc pistons and pins, rings and circlips. You would use this kit to replace the old steel liner cylinders used from 1977-1980 that were prone to wear prematurely and were not very stable when bored first oversize.
