My last ride of the year was 7 days ago. I rode for 8 hours pretty much WOT most of the time and only shut off the engine to refuel and fix the only unreliable component of my build, the SBP shifter kit that requires a chain adjustment every 2 hours of use.
I ALWAYS replace the cheap junk chain that comes with the china kits and tack-weld the tensioner. I have no reliability issues at all riding over 100-150 miles a week.(knock on wood)
sounds like something is loose and moving
