Stock replacement oil filler and clutch adjusting caps for Sportster primary covers.

Hex head replacements for the original slotted oil filler and clutch adjusting plugs on Sportster primary covers. Compared to stock plugs they allow for an easy and mar-less loosening/tightening, particularly when you don’t have the special tools.

Our complete gear sets include all necessary sprockets to properly overhaul a 4-speed transmission for Harley-Davidson Sportster models. In addition to the standard ratios, we also offer “close ratio” sets that feature a longer input gear pairing for a sportier shifting experience.
The standard set has an input gear ratio of 18/26 (1:1.444), while the close-ratio set uses 17/27 (1:1.588) for tighter gear spacing. The 4th gear remains at the factory standard 1:1 ratio in both versions.
These gear sets are ideal for transmission rebuilds and performance upgrades on Harley-Davidson Sportsters, ensuring precise fitment and high durability.

Hotter cams for Sportster engines. Most of our cams directly bolt in and require no additional head work. Kits for 1981-84 engines differ from earlier models in that #4 cam has no tach gear. Cams for 1991 Evolution Sportster can be used with non-adjustable pushrods.

Include all gaskets for top end overhaul.

Each complete kit contains all necessary gaskets for the complete overhaul of one engine.

Complete kits with all necessary parts to convert or restore K models and Sportster 1952-1978. No more trouble to collect all the small parts. The kits for Kick- and E-Start include a polished sprocket cover which accepts the stock electric starter.

Nice reproductions of the transmission trap doors for Sportster models from 1957-1983 to replace damaged original parts. It was developed in 1954 by Harley-Davidson to simplify transmission repairs, because the engines of the early K models 1952-1953 had to be split to service the transmission, due to the absence of this trap door.
