He was the first to build 4000 plus horsepower V-8 race engines. Keith now has put all his knowledge and experience into the manufacturing of aftermarket Harley-Davidson pistons. The use of the special hypereutectic aluminum alloy, developed and race tested by Keith himself, makes a piston that is light-weight and has more features than an expensive forged piston. These features include reduced wear and decreased fuel and oil consumption. Tighter running tolerances result in an engine that runs quietly and provides more power. The low heat transfer of the hypereutectic aluminum alloy keeps the skirts cool so piston expansion is minimal. Test engines have been run with as little as 0.0005" (1/2 thousands) piston-to-wall clearance. The high ring placement reduces detonation and increases the top ring temperature. Keith Black pistons will make maximum power at 2 to 4 degrees less total timing than conventional pistons. Available in standard and over sizes for Knucklehead, Panhead, Shovelhead and Evolution Big Twin models from 1941 to present and Sportster 1200. Also available in various Big-Bore and High-compression versions as well as a Big Bore kit that will convert your 883 Sportster into a High-Torque 1200 model. Pistons are competitively priced. Note 1: Complete piston kits contains 2 pistons with Hastings chrome moly rings, piston pins and circlips. Note 2: A limited number of KB pistons have the ring grooves crossing the piston pin hole. In order to have the piston rings properly supported these pistons come with piston ring support rings. As support rings do not have a sealing function they do not have to be replaced when you install new piston rings, but sometimes new ones are needed because a ring is lost or broken. 2206 KEITH BLACK PISTONS 1340 Shovelhead (80CI) Piston, pin and clips Hastings piston ring kit for 2 cylinders Hastings piston ring kit for 2 cylinders Each Cast Chrome-Moly 047511 049000 231210 3.498" Std. 047512 049001 231211 3.498" +.010" 047513 049002 231212 3.498" +.020" 047514 049003 231213 3.498" +.030" 047515 049004 231214 3.498" +.040" 047516 049005 - 3.498" +.050" 047517 049006 - 3.498" +.060" 047518 049007 - 3.498" +.070" 1340 Evolution Big Twin Piston, pin and clips Hastings piston ring kit for 2 cylinders Hastings piston ring kit for 2 cylinders Each Cast Moly 047554 231240 231250 3.498" Std. 047555 231244 231254 3.498" +.005" 047556 231241 231251 3.498" +.010" 047557 231242 231252 3.498" +.020" 047558 231243 231253 3.498" +.030" XL 883 Evolution Sportster 1986-2003 Pistons, rings, pins and clips Hastings piston ring kit for 1 cylinder Pair Chrome-Moly 047539 231220 3" Std. 769016 231224 3" +.005" 769017 231221 3" +.010" 769018 231222 3" +.020" 769019 231223 3" +.030" 769020 - 3" +.040" XL 1000 Ironhead Sportster 1970-1985 Piston, pin and clips Hastings piston ring kit for 2 cylinders Hastings piston ring kit for 2 cylinders Each Cast Chrome-Moly 047471 048360 231190 3 3/16" Std. 047472 048361 231191 3 3/16" +.010" 047473 048362 231192 3 3/16" +.020" 047474 048363 231193 3 3/16" +.030" 047475 048364 231194 3 3/16" +.040" 047476 048365 - 3 3/16" +.050" 047477 048366 - 3 3/16" +.060" 047478 048367 231197 3 3/16" +.070" XL 1200 Evolution Sportster 1988-2003 Piston, pin and clips Hastings piston ring kit for 2 cylinders Hastings piston ring kit for 2 cylinders Each Cast Chrome-Moly 047549 231240 231250 3.498" Std. 047550 231244 231254 3.498" +.005" 047551 231241 231251 3.498" +.010" 047552 231242 231252 3.498" +.020" 047553 231243 231253 3.498" +.030" 1200 Panhead & Shovelhead (74CI) Piston, pin and clips Hastings piston ring kit for 2 cylinders Hastings piston ring kit for 2 cylinders Each Cast Chrome-Moly 047491 048380 231200 3 7/16" Std. 047492 048381 231201 3 7/16" +.010" 047493 048382 231202 3 7/16" +.020" 047494 048383 231203 3 7/16" +.030" 047495 048384 231204 3 7/16" +.040" 047496 048385 231205 3 7/16" +.050" 047497 049000 231210 3 7/16" +.060" 047498 049001 231211 3 7/16" +.070" 047499 049002 231212 3 7/16" +.080" These top quality pistons are used by motor builders all over the world.
