Using the cylinder head finder on my scooter only gave one valve size option. Not knowing that two valve sizes are common on my scooter and assuming searching will find all available ones, I'm ordering the wrong cylinder head. There are sellers on other sites (eBay) who post very nice charts to let you know there are two options and how to make sure you order the right one.
