ok i have a piston for a 250cc small honda 4 stroke, i cracked a small pice off of the botom of the skirt and i grinded them both down to match, so you would never notice but the botom of the piston is about a litle more than 1/8 inch shorter. iv fixed seized up 2 strokes by grinding niks and grooves off of the piston and cylinder 100 times without a problem but im afraid that since the piston is shorter it may cause long term effects like oveling the cylender out or something like that. what do you guys think is it worth buying a new piston or not.
if it were me I would get another piston there cheep and then you will know its ok
well, i figured people would say that, but it is expensive for the buget and not worth it if i dont need it.
Depends on how the bike will be used.
As a yard dog: The old piston should due.
20 miles out in the woods: get a new piston and rings.
