I would be on the safe side if that was a resale bike and get the jug redone. If it's for yourself/family than run it. worst could happen is you need a new top end sooner than later. There is a company that puts their name on it for other countries called Langcourt. I use them exclusively in Alabama and have not had bad success. Other opinions will very.
I plan on keeping this bike for myself and for my son once he gets a bit older but since i am in Canada parts seem to be a little more here. I would like to have it replated but in my area it is $300+ and i can buy a brand new cylinder for that much. I dont want to even think about sleeving it even though it would be cheaper.
