KXcam22:
That sure looks like an iron liner from the pics. Normally you don't see that thick band in the ports since plating is very thin. If so you can just bore it the next oversize. You will have to find an aftermarket oversize piston first. Cam.

I've had over 5 of my bikes sent to Eric Gorr for big bores and he always had them sent to US Chrome for the replating while he had it.

5 big bore bikes, at least 3 of them rebuilt and replated again years later. Never had an issue with them always top notch plating.

so why would the previous owner have put a sleeve in this cylinder? what are the disadvantages of using a sleeved cylinder- what are the advantages?
Hillclimb#42:
I think that the plating is where the life span is at. I mean to say the nikasil/ electroplating lasts longer. I am pretty sure that these guys have said you can plate bored cylinders, just the same. I think the benefits to me are that with plating I can stay stock piston size and always be able to get top end kit, bammo.
I've always had stock cylinders. I know when you talk about boring out kx cylinders its minimal at best because of powervalve, right?
Thomas Racing Service, Trinity Powersports also good engine builders. Also, what about the guys on here? 560 done Stewart? :-D
Kawasakinut:
so does anbody have any suggestions of what i should do. should i just buy a brand new cylinder, should i have this one rebored to correct the flaws in the bore, or can the sleeve be taken out and the cylinder be replated to stock condition?
