We would like to welcome JIMS to the blog!
The new JIMS 131-cubic-inch race engine, previously available for early models, is the only big-inch powerplant that fits stock late-model Softails. The 131 features the same stroke as the JIMS® 120 at 4-1/2 inches, but carries a larger bore diameter of 4-5/16 inches.
Increased air intake with CNC ported heads to flow air effortlessly
Upgraded oil pump to the high-flow design found in all current H-D TC engines
New JIMS® Billet Cam Support Plate utilizing the new Harley-Davidson® Hydraulic cam chain tensioners
The latest in high-performance tappets, JIMS “Pressurized Oiling” Powerglide II
Power delivery is as smooth off the bottom end as stock, with a wide powerband of roll-on punch. Combined, these enhancements take the 131 to a new level of performance and reliability unmatched in race engines. All of the legendary JIMS® Twin Cam® Race Engine family are available through authorized Harley-Davidson® dealerships.
