Can someone tell me about how many miles you get before the nylon guide that is on the primary chain tensioner needs to be changed? I have a 2005 Road King with 42,000 on it and I am riding it from Picayune Ms. to Fairbanks Alaska in August, about 4,600 miles one way.

 

I just changed mine at 115,000 miles, but it is not nearly worn out, would probably go another 35,000.

 

90k on mine. nothing wrong with it.
