Screamin Eagle 4" Big Bore 110 cui Kit

Art no.: 92500039
incl. tax, plus shipping 

When it comes to increasing engine power, there is no substitute for more cubic inches.

  • With efficient filling of the air/fuel mixture, the bigger the displacement, the more power your engine can produce
  • In the past, the only way to increase the bore of your 96 or 103 cubic inch Twin Cam V-Twin motor was to tear down the motor and re-bore the engine cases to fit larger bore cylinder spigots
  • It was a labor-intensive – and expensive – process
  • Now, you can take your 96 or 103 cubic inch motor to a full 110 cubic inches without removing the engine from the chassis
  • The Screamin’ Eagle team has engineered a 4" Big Bore Cylinder and Piston package that increase the internal bore from 3-7/8" to 4", without increasing the outside diameter of the cylinder spigot
  • The cylinder slips into the existing case bore without modification
  • This kit will add a whopping 7 cubic inches of displacement for more torque throughout the RPM range
  • The kit includes front and rear cylinders, system-matched pistons with rings and breathers
Note
