wanted cylinder for 73 Jackpiner

[gooey]

I guess the easiest and best way out of my cylinder mess is to replace my cylinder .... so I am needing a cylinder for my 1973 jackpiner ...KTM black motor of course,,,  I have a new standard piston now,, and have located a 3rd and a 4th over,, so I guess just about any useable cylinder would interest me at this point ... trouble is,, I dont know what kinda $$$ to expect to spend ... so YOU tell me .... but be nice,, please  thanx !
