Response to: | 20640 |
Depends on what the extreme bottom of the piston measures. New repro pistons usually measure 2.0805, the bore size recommended by them would be 2.082 , but that's rather tight I would commend 2.0815" -2.0825 giving ya .0025- .0035" clearence ----- ORIGINAL MESSAGE FOLLOWS ----- Can someone tell me how much I need to open up a 125cc cylinder so it will accept a piston/rings that are .020 over?
