Are you tired of burning your hand while you check the oil level on your Harley-Davidson Bagger or Dyna? If so, you’re not alone.
There is no doubt that the lifeblood of your Harley-Davidson’s Twin Cam engine is its oiling system.
Crucial to oiling yet often overlooked are the piston jets. Located deep inside the Harley-Davidson’s engine cases, it’s hard to verify whether the piston jets are functioning properly…until now.

The patent pending, JIMS Cam Cover Heat Sink is designed to help reduce running temperatures of high performance, big-inch Harley-Davidson motors that often run hotter than smaller, stock displacement motors.
The new JIMS Mini Valve Spring Test Gauge No.1090 provides a solution for accurately checking valve spring pressure on Harley-Davidson motorcycles.
This easy to use spring tester may be used in a bench vice or an arbor, hydraulic, screw, or drill press and will check any Harley-Davidson style valve springs, including early
and late Conical Springs.
