Stock ones are the best. If you need to bore it check out the big bores that use the stock m1000 pistons. Do a search on here about the 975 bb for the king kat.

Its on a 03 900, piped,can, air box mod and a 14 to 1 head. Ride from 3000 to 6000 so I will probably have to run some race gas mixed. Thanks

I have had great luck with SPI pistons. They are a nice cast piston for about half the price of seizcos.

for a stock aftermarket replacement piston, spi has been very reliable piston another vote against wiseco...
