What are the numbers??? the numbers in the middle of the piston is what i wanna know....
You're correct. That is a 1.5mm over size or .060". 573 is the series of piston, the last four are the bore size. 6750 is 67.5mm.

Well that is a 1.50mm over-bore. the last size piston wiseco sells is 68.25mm. if you need a piston, only get what you need. dont think that making the piston bigger makes a huge difference. in fact, it can even disadvantage your power. Your engine will run hotter with a bigger piston....
If your piston shows wear, replace it. if your cylinder shows wear, bore it. Once you start to rebuild, make sure you hone, your rings will last longer because the hone seats the rings properly. Also, replace all gaskets., It restores power as well. replace plug are run fresh 32:1 gas/oil mixture...
