Do I have to re-sleeve?

[davham]

'85 Tri-Z, cyl and piston are worn. Piston is 68.71 cyl is 68.79
I assume the previous owner went with a 68.75 piston. Stock is 68. Wiseco website shows pistons up to 2mm over but I'm unsure how far I can go. Anyone know the last bore size before I have to re-sleeve?

Thanks
Dave

you can bore it up to 8 over. factory is 68. yours was a 68.75 so its been bored 3 times. you can bore it a total of 6 times it goes from std.,.010,.020,.030,.040,.060,.080
