BAKER Tin-Type Primary - Nostalgia With Dependablity!

Press Release: HASLETT, MI
Know this; S&S started some s**t. A couple years ago they took the classic Shovel, Pan, and Knucklehead engine designs, and re-birthed them with many modern improvements to address leaks, durability, reliability, and performance. BAKER took the hint and re-engineered the venerable ratchet top and jockey top 4 speeds by integrating the classic external architecture with many modern internal improvements. The only piece of the puzzle missing was the primary. So BAKER took that classic 1936-64 tin design and re-constructed it with billet 6061-T6 aluminum to facilitate alternator left side motor case and 1990-2006 starter compatibility. And the tin primary leaks of the past are gone. The resulting TTP (Tin Type Primary) looks, feels and breathes nostalgia. Kick-only and starter configurations are available with shot blasted ‘raw’ or show polished finishes. The starter version is set up for factory 1.4kw 1990-2006 units. Stock tin derby and inspection covers will fit but the sleek TTP 6061-T6 aluminum covers are pure money. The chain tensioner design utilizes a fine tooth modern L-bracket, giving you plenty of room for any and all configurations.

       The TTP can be run wet or dry. The inner primary incorporates the chain oiler feed and return provisions on the back side similar to factory locations so you can continue to run Shovelhead era factory clutches; with all the fittings & hardware included. For a cleaner look with better clutch function, heat dissipation and dependability the TTP can be ran wet.  By bypassing the conventional stock oil drip and suction lines, using the provided hardware, you can run the TTP just like a stock 1990-2006 primary.

• 1970-E84 Big Twins and custom 4-speed builds
