XR525T Member 16 Member For: 20y 6m Posted 11/12/06 07:11 AM Share Posted 11/12/06 07:11 AM (edited) Hey guys n' Gals.Just today after I filled up my tank I have noticed when I am at high revs and lift off the throttle the blow off valve makes its usual flutter but also a high pitched whissle for a split second that I have never noticed before.I checked all the hoses from the blow off and they look ok. Does anyone have any idea why this may be? I dont want to go back to ford for the SECOND time this week !!James :D Edited 11/12/06 07:12 AM by cArSiK Link to comment Share on other sites More sharing options...

It used to happen to mine before it lunched itself, with my help.High revs then a sudden backoff, the bands can't slow it down quick enough, and it skids.
