surely there's a shop in your area that could bore it. the real question is why does everyone want to hone it? is it not bad, and you just wanna bore it for peace of mind? i know on my it200 that is now on last bore, i wish a hone was all it needed - it200 cylinders do not grow on trees... make sure the ports are chamfered too.... have had a few cylinders come in that were not chamfered, don't know why....
