My CRF 450R was boiling over every ride,no matter if I was on a fast mx track, sand or single track.The weather has cooled down a little, but it has definitely helped.crf 450 was losing coolant from cap to overflow pipe but was below the low fill mark, hit the forums and drivers said the stock caps were weak and wasn't close to the high mark after a short drive at 90 degrees air coolant so I ordered this DRC replacement and 2 days later I picked it up and filled the tank to the max line to see if the coolant expanded or vomited, no, this cap is 100% quality. rotate to tighten.I purchased the DRC High Pressure Radiator Cap and a set of high pressure silicone radiator hoses and the boiling over has stopped.
