The Jagg Manual By-Pass Valve acts as a manual thermostat, allowing you to by-pass the oil cooling system for cold-weather riding or for faster warm-ups on cool days. Works with all oil coolers.* Durable anodized billet aluminum construction. Compact in-line installation.
The Jagg Manual By-Pass is supplied complete with all necessary hardware and easy-to-follow installation instructions.
Installation note: If the oil hoses between the oil cooler and the oil source are too short, the oil cooler by-pass valve may not fit in the oil lines. Jagg mini by-pass valves require at least 3 inches of straight hose.
