"new pistons on '72 T120"


          

I just opened up my T120 motor and discovered a hole in the top of my left piston, ouch?! My question is can I replace with .20 over pistons without having the cylinder bored? The numbers on the current pistons is 70 94 88 ID .15. I should probably have the cylinder measured first , then measure a .20 piston and go from there? Trying to take a cheap way out as riding season is here........

You need to measure the bore and buy pistons accordingly. You cannot insert a .020 oversize piston in a standard or .015 over bore, it will be way too tight if it goes in at all. I wouldn't trust the number on the piston. Pat
