My piston size?

the piston is a 67.5 but if its a wiseco piston that was in it here are the part numbers that should be stamped on the top 67.5 (573M06750) and cylinder i cant tell. just check the top of your piston for a stamping and then list it back on here and we can tell you exactly
 
Can't read

my piston got a hole burned threw it,I can't read anything its super ruff on top.. So its not a stock bore? .10-.20-.30? I will get a Wiseco piston

Thanks

no clue what piston you have then? but on the sealer side i just use dry i think i put a little yamabond on my bottom cylinder gasket on the corners to keep it in place while putting on the jug but i forgot the rebuild on mine was 4 months ago
 
jug between head can be dry for sure though. but i wouldnt put any on at all the whole changing the height of the head could be bad
