High performance just got a lot easier and more affordable with S&S Cycle's CNC-ported B2 cylinder heads. In the past, S&S's B2 Special Application heads, that were used on the now legendary Tribute 145 engines, were often hailed as the best choice for very large displacement V-Twin engines. Now S&S Cycle offers CNC-ported B2 cylinder heads that are even better—providing added convenience, economy, and performance at the same time. Convenient, because they now fit 2008-later bagger front motor mounts and the new two bolt exhaust mounting flange is a lot easier to work with. Economical, because riders can use stock exhaust pipes, or existing 2 in. header systems. The increase in performance comes from increased flow of CNC-ported intake and exhaust ports. Heads features stock bolt pattern and require special pistons, intake manifold flanges, and pushrod length for installation. Features and benefits: * 106cc combustion chambers * Oval intake ports bolt up to S&S throttle Hog 70mm throttle bodies (2008-up touring applications) * Stock-style breather system—compatible with stock and aftermarket air cleaners * Large 2.200 in. intake and 1.800 in. exhaust valves * Machined for stock sensors—EFI friendly * .660 in. lift S&S valve springs with titanium top collars * Head kits include valves and valve springs * Requires special pistons, pushrods, manifold intake, intake flanges and seals, and an exhaust adaptor kit (sold separately) * Kits do not include gaskets, hardware, or intake and exhaust flanges (these parts must be purchased separately) Fitment: * S&S only stocks the late model 4 1/8 in. bore versions as off-the-shelf items, but heads for other applications and individual front of rear replacement heads available by special order only Possible options by Special Order: (final price varies depending on selected special option requests by customer) * Cylinder head sets without valves or springs individual front, or rear heads * CNC-ported intake and exhaust ports—more air, more power! * Two-bolt exhaust flanges—can accommodate stock exhaust headers, existing 2 in. headers, or build your own 2 in. exhaust system * Machined for 2008—later bagger front motor mount * 4 1/8 in. to 4 3/8 in. bore sizes * Stock 1999-up, S&S, or other cylinder stud patterns—other patterns subject to approval * Machined with or without S&S electric compression release * Choose from a variety of pushrod geometry machining styles * Choose from a variety of different chamber sizes * Individual front of rear heads available by special order * Available in wrinkle black, gloss black, silver, or natural

Improved Racing oil cooler adapters have a low-profile for more header clearance. The adapters are machined from a single piece of billet aluminum and black anodized. For additional clearance with reliable sealing, they come with aluminum gaskets fitted with Viton® seals, and the adapter mounting holes are counter-bored so the mounting bolts fit flush with the adapter surface. Select Improved Racing oil cooler adapters are also available with a built-in thermostat. Oil coolers help prevent the oil from getting too hot, but are also prone to lowering oil temperatures too much, especially in colder weather or during highway driving. The rebuildable thermostat speeds warm-up and helps reduce engine wear and horsepower losses by preventing oil temperatures from dropping below optimal levels. Features and benefits * 100 percent bolt-on solution; no fabrication, bending, or line modification is required * Viton® seals throughout for maximum reliability * Oil exiting the adapter is filtered oil * 6061 T-6 billet aluminum construction with black MIL-A-8625 Type II anodized finish * Standard female -8 AN O-ring boss threads for optional anodized adapter fittings in your choice of -8 AN, -10 AN, or -12AN lines * Depending on application, includes port(s) for oil sensors or turbo oil supply * Includes all necessary hardware * Limited lifetime warranty
