stupid Fools at Yamaha stamped half the numbers upside down so its hard to make out.
The one piston has 3 and L stamped inside, and next to the yamaha stamp inside the piston it states 13P. On the otherside it says ART.
the other piston has what i think says 4 10 29 , YAMAHA , ART , 2 and L
The numbers on the top that are barely readbale say 946

On the jugs there is a number printed on the sleeve. This three digit number is the bore size 75.??? subtract the pistons 74.946 gives you the stock clearance when new.
