February 11, 201511 yr Hi do the fans constantly run on trials bikes in a wooded up area where there is no moving air passing through the radiator as my rev 3 fan seems to run constantly if im in the woods climbing up hills and if I leave it idling it doesn't stop nore a slight hire revs off idle It doesn't ither .but could I have a blocked radiatore
February 11, 201511 yr If a motor is working (climbing) it will run. For peace off mind pull apart the water pump. Depends on the year of Rev 3, but you could have a corrosion issue.
February 11, 201511 yr Author Ok well I have replaced the cases as it did have the typical corrosion problem I have just ordered a impeller for the water pump . But I can't see why it should run on unless the radiator is partially blocked not cooling the coolant properly
