Hello everyone,

I recently found a 67 Yamaha YDS-5 in a barn and wanted to get it running. The serial number on the frame matches the engine and has me pretty excited. I got a service manual off of eBay and it states the spark plugs are NGK B-8HC. I have no idea what that means or which would be the be the best to go with since there doesn't seem to be a cross-reference for that plug. I am new to restoring motorcycles and want to get it running before going hard core full New-Old expensive restore. Any advice is greatly appreciated.

Just had a quick Google...
They're certainly still available and there are a couple of alternatives :D
Got a pic of the beast?
