Keep tabs on your Oil Pressure with this Rocker Box Mounted Gauge Kit

Just because you don’t own a motorcycle with a fairing, doesn’t mean you can’t monitor the life blood of your motor. K and G Cycles ( is pleased to bring you a Rocker Box mount Oil Pressure Gauge Kit, from a brand you know and trust – Sifton. Your oil pressure can tell you a lot about how your bike is functioning. Pressures too low or too high can indicate issues within the motor. Oil pressure is higher when the engine is cold due to the increased viscosity of the oil, and also increases with engine speed until the relief valve opens to divert excess flow. Oil pressure is lowest under hot idling conditions, and the minimum pressure allowed by the manufacturer’s tolerances is usually given at this point. Excessive oil pressure may indicate a blocked filter, blocked oil gallery or the wrong grade of oil. Low oil pressure indicates worn bearings on the crank shaft or a broken oil pump.

Oil pressure is an important factor in the longevity of most internal combustion engines. With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big ends and camshaft bearings. Other components such as cam lobes and cylinder walls are lubricated by oil jets. Sufficient oil pressure ensures that the metal of the rotating shaft (journal) and the bearing shell can never touch, and wear is therefore confined to initial start-up and shutdown. The oil pressure, combined with the rotation of the shaft, also hydrodynamically centers the journal in its shell and cools the bearings. Such a bearing is known as a fluid bearing.

Sifton has engineered a way forocker box oil press monitor 40-9971r just about all 2000 and newer Twin Cam motorcycle to have an easy to read oil pressure gauge installed on the rocker box. The installation of this kit allows the rider to real time input from the motor and deliver current performance levels. The liquid filled 60lb oil pressure gauge features a silver face, stainless steel case, chrome rim and weather resistant sealed lens. Since it has a liquid filled face it eliminates the needle bounce giving you a constant reading. For ease of installation, the gauge has a 1/8″ National Pipe Thread male rear fitting. Speaking of fittings, these kits are made to fit the following bikes:

FXST 2000-UP
FLST 2000-UP
FLT 2000-UP
FXD 2000-UP
