honda z50a exhaust valve

Post by upnorth62 » Sat Jun 13, 2020 11:24 am

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 ?
Many thanks

No worries panic over , I removed valves and re- lapped them :D , works a treat.
