S&S Cycle 110″ Big Bore Kit For Harley Twin Cam
There are multiple sayings that come to mind here- “There’s no replacement for displacement” and “Bigger is better”. This kit address both of them. The upgrade yields excellent results with the stock cylinder heads. No need to bore or split your existing cases, just swap the cylinders and pistons.
Features:
- 4″ bore, 4 3/8″ stroke, 10.5:1 compression with the stock heads
- Cylinders constructed from premium aluminum castings with cast-in iron liners
- Kits include cylinders, pistons, rings and head, base and exhaust gaskets
- Black or silver powder-coat finish with polished fins
- Made in the USA
- Sold as a pair
Note: Engine projects like this may require a skilled technician. It is the responsibility of the person assembling the parts to check all clearances and assembly specifications.
