Honda used some non prefered pitch threads, but still standard, in some places.In all honesty i would buy just the sizes you need as some will need repair so you need helicoil kits anyway.Most used size would be 6 x 1 and if its just a repair a plug tap will do but to tap a blind hole you need a taper first.Tell me what you want to repair and ill tell you what sizes you need
If you want a selection of taps and dies Tracy Tools have some for £20. You can also call them for a chat to discuss exactly what you need. They have been around for years and are a reccomended source of quality engineering taps and dies. I've used them many times and never had a problem with the quality of their tools.https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwikiOqIpanqAhUsQhUIHc5LDjQQFjAAegQIARAD&url=https%3A%2F%2Fwww.tracytools.com%2F&usg=AOvVaw0SKoLqgxcwMYaqtZpNffdU
