Oho Sleeved cylinders are not as bad as people in Pakistan consider them to be, there are different cast iron grades available here, If you choose the best grade, get the bore within specs and in the end get the honing done with a proper honing tool, no reason the sleeved cylinders won't last as long as genuine ones do. afterall the material used in japanese cylinders is also cast iron you know. and just to be on the extra safe side to prevent a seize situation, one can increase the flow on the engines oil pump.
But if one truly likes to have a japanese cylinder, he should dispose the cylinder off the day the 0 sized piston dies, because after the 0 size regardless of the japanese sleeve inside, It will need to be bored and then honed by the locals to accept a .25mm or .50mm Piston.
Last but not the least comes personal experience, I have a spare rxz cylinder which has a 62mm Piston and a local sleeve in it, stock rxz135 Piston is 56mm for your kind info Brother. Its been 4 months since I have been using that Cylinder with no seizes at all and is still going strong.
