tlrider Posted June 4, 2013 Report Share Posted June 4, 2013 Gentleman, I have developed a thunk in my TLR 250F forks when they extend. I'm guessing the rebound dampers are on their way out. Does anyone know if the rebound damper is a spring or some time of an elastomeric bumper? Do you know a part number and where I might obtain a set? Cheers!

tlrmark Posted June 5, 2013 Report Share Posted June 5, 2013 Classic symptom of insufficient fork oil volume as Mr.B40 has said. Quote Link to comment Share on other sites More sharing options...
tlrider Posted June 5, 2013 Author Report Share Posted June 5, 2013 Thanks Gents, I was thinking low oil whilst riding it this past weekend. I don't have leaking fork seals so low oil didn't seem right. Would old oil of low viscosity behave similarly? Quote Link to comment Share on other sites More sharing options...
b40rt Posted June 5, 2013 Report Share Posted June 5, 2013 Ambient temp will also be a factor. ATF is approx 7-5 weight. Cheap for forks if you are just trying to flush them out. Quote Link to comment Share on other sites More sharing options...
tlrider Posted June 5, 2013 Author Report Share Posted June 5, 2013 It was unseasonably hot this past weekend and I believe I have 5 weight in the forks. An oil change is in order! Quote Link to comment Share on other sites More sharing options...
