S&S® 106” BIG BORE KIT
This kit yields excellent results with stock cylinder heads, but adding a performance cam is recommended to get best performance and easier engine starts. For most applications, the S&S® single bore EFI throttle body with a teardrop air cleaner or tuned induction is recommended. 08-Up Touring models will need to use stock intake or Screamin' Eagle 58mm throttle body and Race Tuner or Pro EFI Super Tuner.
- No need to bore or split the cases, just swap out the cylinders
- Matching silver or black wrinkle powder-coated finish to match stock finish
- Superior cylinder liner material over stock, drag and dyno tested
- 3.927” bore, 4-3/8” stroke, 10:1 CR on stock heads, 9.7:1 CR on S&S® 89cc heads
- Fits 07-Up Big Twin models
