Bates BattBoy HM5
Modern gel or Li-Ion batteries offer a significant advantage - they are leak-proof. Those who ever experienced spilled acid in their horseshoe oil tanks will highly appreciate this fact. On the other hand, owners of classic bikes do like the looks of their original energy store and the corresponding cover and mounts. With a Bates BattBoy Battery Box you can have the best of both worlds, because what looks like a period type HM5 6V accumulator on the outside can house a safe, modern battery within. Just hook it with two eyelet wires to the terminals on the bottom of the lid and you are all set. Perfect for 6 to 12 volts electrical system conversions, too. When using suitable Antigravity versions you even have some storage room left for a few small spare parts, safety vest, Cuban cigars, etc. Ain't this one heck of a cool solution for an old problem?

PanAm Oil Slide
Oil change without a mess! This rubberized aluminum alloy sheet allows you to form an individual funnel or trough to direct your waste oil from the hard-to-reach oil tank drain hole or oil filter plate to any suitable container. Of course, you can also use it to fill fresh oil into your tank. Tapered at one end so it can be shaped to reach tight spots. You can reshape and use it a thousand times and on different bikes. With suspension eye so you can hang it up for drip-off. Easy to clean.

Our electric start system just got even more stealthy....

PanAm Oil/Ignition Shut-Off Valves
Pre-TwinCam engines have a spring loaded ball check valve to prevent the engine oil from seeping down to the crankcase. These check valves don’t last forever. If you try to start your engine after a lengthy period of inactivity (e.g. winter), the oil in the crank case gets forcefully ejected via the breather. Creating an ungodly mess on your garage floor....
