Has anyone had any experience with fitting an oil cooler to a YZ 400/426. I had a JAGG Oil Cooler on my XR 650 and was told that it would greatly benefit the engine's life-span. Does anyone know if someone makes a similar system for the YZF? Even though it's liquid cooled, it would seem to me that an oil cooler would also benefit this motor ... especially if prolonged high speed riding might be a regular occurance. I haven't checked with JAGG yet (but intend to shortly). TX!
