Best way to tell is if you look in the inlet side of the carb you should see a small curve cut in the bottom of the slide. If you don't and it's in the back (outlet side) they're in wrong
If you have good compression and the pistons look good (no heavy wear) just run it. I've seen bikes that are 10-15 years old with the original pistons that run good
