      Hello, I'm looking for a write up on how to add mileage to my replacement xj650 seca speedo.
      New speedo is ~7k so I need to ADD mileage to reflect the actual ~13k mileage.
      Would you be willing to email me a procedure?
      Does it explain how to get the bezel off? Looks like someone tried to pry the one off my old unit.

    2. Robert24b
      I saw your writeup on the gauge swap. 2 questions how are the gauge bezels removed and ultimately the lens? P/O said they replaced the gaskets, looks like they pried the bezel all the way around. Is this the correct/only way to access the insides?
      Also, how is the silk screening on your indicator lights so nice? Most of my lettering is rubbed off. Is there a way to redo it?
      FWIW, I have an 82' xj650 seca.

      Biggie-sorry to bug you - I have a 1981 X550 Seca -replaced shims according to factory specs and at 6000 rpm there is a clacking sound (sorry, can't describe any better), what am I missing? I really like this bike but this frustrates the living daylights out if me.

      Howdy! Wanted to see if you could help. I just replaced the clutch plates on my 1982 xj650 and adjusted the clutch to where it should fully disengage but it seems to be slipping. I even loosened the clutch adjustment so there was a bit of slack and it was even lurching forward with the clutch in so I know it wasn't the adjustment of the cable or arm. Still slipping and not sure what to do. If you can help thank!!!

      1983 XJ 550K: I have two of them and one runs perfectly; the other one did until early last summer. It has no spark. All electrical connections cleaned and greased. All components per repair manual I have are satisfactory except starter circuit cut-off relay but does click when the ignition is turned on. All continuity tests ran are satisfactory. Suggestion on possible problem and best manual?

      Hey buddy! I'm having a Hard time with the oil seal behind the pick up coils at the left side of the engine of my XJ750... I replaced it about 4 times, but still leaking, should I have to disassemble the engine to replace that seal? It is the one behind the magnetic pick up coils, the oil seal is the 32-45-6.5 2h7, the engine its fine, no cracks in it... Help!

Thanks in advance!
