S&S BIG BORE KIT FOR 1986-2013Boost any 883cc Harley-Davidson Sportster to 1200cc. No machine shop?
No problem, no machining is needed. Dont want to rebalance your stock
883cc flywheels? You dont need to since these pistons weigh the same as
stock 883 pistons. Cylinder head modification is also not needed. The
dished piston dome keeps compression down to a streetable 9.4:1 with
stock 883cc heads. Installing this kit takes the same time as replacing a
stock top end. Its just more fun when youre done.
