my cylinder had to be bored out to 1mm over..i ordered the stock piston instead of the wiseco to save some money and i was just wonderin what the stock compression ratio is. the piston that was in there before was .5mm over and had 10.5:1 ..will i be able to tell a difference with the lower compression?

 

a stock-bore piston will not fit into a cylinder that is 1 mm over.

 

i meant suzuki piston sorry..the piston is 1mm over
