I bought a early honda z50a minitrail(k1 )engine as a nonrunner ,the exhaust valve is leaking badly ,(with the head upside down it leaks water out in 15secs or so into the exhaust port) can I use a c50/70/90 valve, I had a quick browse on ebay ,but not sure what type to get . will the valves require a little lapping in if seats ok ?
