Instructions

With no need to rebalance flywheels, bore crankcases, or bore cylinders, this kit is about as easy as it gets. Consisting of the largest bore we feel can safely be used in a cylinder with a stock spigot diameter, this kit brings a new definition to the term 'big bore'.


FEATURES AND BENEFITS

  • Largest bore we feel can safely be used in a cylinder with a stock spigot O.D.
  • Bolt-on 9 to 10 cubic inches – cylinders do not require crankcase machining to install
  • Piston weight for 97" & 106" kits are the same as stock, requiring no flywheel rebalancing
  • Forged coated pistons are compatible with stock or S&S Super Stock® 89cc heads
  • Valve pocket recessed in S&S pistons are enlarged for oversize valves and higher lift cams
  • Silver or black wrinkle powdercoat cylinder finish color matches stock Harley-Davidson® finish



KIT CONTENTS

  • Piston set with rings
  • Top end gasket kit
  • S&S cylinders
