Re-Sleeve Vrs. Re-Plating Cylinders
Why Re-Sleeve?
Resleeving a cylinder is required when your stock cylinder has been bored to the last offered over size piston or when a chrome plated cylinder is damaged.
Advantages of sleeves over platting are 1) you can work with steel to get perfect piston to cylinder wall clearance, 2)you can bore steel to fit an oversized piston rather than throw the cylinder away. 3) Plated cylinders cannot be properly ported, as the plating has to be blended around the insides of ports, once this is ground the platting will begin to strip off causing serious engine damage. 4) Rings seal better to a steel sleeve, plating is much too hard for rings to properly seat. 5)Pores in a steel cyilnder lining hold oil for lubrication for longer lasting piston & ring life. 6)No thin plating to peel or flake off. Manufactures use Plating to save on production time and money. Sleeves are recomended for all types of riding including racing.
Cylinders can be re-plated but the cost is about $200 every time it is worn or damaged. Once a steel liner is installed it can be re-bored to fit oversized pistons at less that $50 generally over sizes in .010 020,040 060 & .080 are offered. By the time you used up all the bores you will have spent around $350 in machining costs. If you needed to re-plate each time you will have spent $1200!
