IMPORTANT FACT:   It is misunderstood by some riders that if the thermovalve fails to operate it will block oil flow and damage the motor. This is not true. If the thermovalve failed in any operating position, oil flow would not be disrupted.

Technical Representative Information
  • Small light weight
  • Mount anywhere (hoses are enough support)
  • Starts opening at 160-5 °F fully open at 180-5 °F. Holds maximum temperature at 190 °F on hottest day.
  • 26% greater oil flow (no restrictions, compared to stock fittings)
  • Lifetime guarantee to the original purchaser
  • Permanently etched logo & plumbing directions (no mistakes)
  • Barbed nipple hose fittings (no oil leaks)
  • Fail-safe valve (cannot restrict oil flow to motor)

Simple tests to check oil cooling system

"Stand still test"

Start motor, let idle (about 1500 RPM) watch temperature gauge (if there is one) in reservoir. Touch oil cooler at inlet side at frequent intervals. When oil reaches 160-165 degrees, heat will be felt at the cooler inlet.

"In motion tests"

When riding on a cold day reach down and feel cooler inlet side ( only if your arms are long enough to do it safely ) no heat will be felt. On hot days this will be opposite.

A further test while riding down the highway on a HOT day, feel the temperature difference from inlet to outlet ends of cooler. (Be careful touching inlet end - It is hot!)
