Yes there is a standard size. Honda is one of the few companies that will take the standard size and then make a few sizes each direction from it. The honda Green is the standard size for a honda. You can run all standard if you like but you need to measure the given clearance accurately to make sure that the standard size in going to be within usable limits. Thank You.

To measure accurately, you need a micrometer and a bore gauge. Micrometer at the very least...you can measure a bore with a micrometer but you have to find the smallest and largest numbers depending on whether its a journal or a bearing end. I've done this and measured accurately even though its not recommended.

Plastigauge will only yield an estimate, its worse IMO than using just a micrometer.
