      Yes, the P.O. could have very well clamped it at the bottom and that part is now oval inside. If the tube never gets that far in with...

      Well, that happens when the lower was clamped in a vice and is now oval inside instead of round, lol. We had to replace one of the...

      5twins replied to the thread Front brake.
      Yes, it can be hard sometimes to re-fill a completely empty system and get it to build pressure. I start out using a Mityvac vacuum pump...

      Maybe try drilling into the EZ-Out with a small drill bit? Maybe if it catches, it will spin the broken part out?
    • 5twins
      So, are you saying you ran the compression tests using the electric starter to spin the motor? That would do it, lol.

      5twins replied to the thread 1974 TX650a Carburetor Question.
      And what size was in your carbs? The original poster found Z-4's in both his sets, apparently from the factory.

      5twins replied to the thread 1974 TX650a Carburetor Question.
      Well, it's entirely possible that the size listing (Z-6) in the parts manuals are wrong, and that the Z-4 is the right size. What size...

      I think I'd match them to the original's length first, then if still too soft, shorten only one one more "loop". Only do one at first...

      5twins replied to the thread First Bike - 79' XS650.
      Yes, sounds like a loose valve. Your idle speed is a bit high. The spec is 1100-1200. You can download any and all the manuals for free...

      Well, it definitely looks longer, by 3 or 4 coils, but not an issue if you're shortening them. Here's some "reference" pics ...

      I suggest 4 bolting the plate on, and with a sheet of rubber between it and the bracket (section of old inner tube would work).

      If the pits in the piston are above the section that moves through the seal, then they would be fine. The section of piston that sits...

      I've found my spoke wheels, front or rear, usually require about 1 to 3 ounces of weight to balance them. With the about 3/4 oz. weights...

      Going in half turns to adjust and set the mix screws is pretty big steps. I only go in 1/4 turns, reducing that to 1/8 turns when I get...

      You need to de-burr the holes when you drill a disc. You don't want to countersink them, just knock the burrs off and that raised edge...

      Sync the carbs really good (build your manometer). A bench sync only usually gets you close.
