  2. 20's production numbers? Harley, Indian and Excelsior?

    I've thought about this for some time and thought I'd pose a question, only part of which I can shed some light on. I'd like to see production numbers for the big 3 American makers for the period...

    Did you just bore the X rod bushing to fit the larger HD wrist pin, or somehow fit a smaller pin in the piston?

    I plan to use EL pistons and bore / hone the bushing to fit the new pin. The UL...

    Tell me more about your UL piston fitting, no issues I assume?

    Also, I'm very curious about the balancing, did you change anything? The UL pistons are quite a bit lighter! I'll be doing the...

    Dan,

    I doubt that your cylinders are re-sleeved, picture of that?

    If your bore and piston measurements are correct, that is way too much piston clearance, .026". Sure, the motor would run but...

    Jerry,

    Not sure yet.... I'm planning to fit them in my 24 Big X. Cylinders are getting a NikaSil coating now. A standard bore X, honed +.005" will fit just right with a +.020 EL or UL piston. UL...

    Best EL pistons?

    Looking for input on the best EL pistons to use. Probably some junk ones out there so want to avoid those, looking for the best quality ones available. Hope you knuckleheads will respond!

    Thanks!...

    Cotten,

    Yes, the X rods are different than most. The big end is super thin and spindly, the tops are heavy. To make matters worse, the big end does not have a replaceable race, nor is there room...

    Cotten,

    As mentioned in my initial diatribe, I came up with a balance factor of about 23%, which is nuts! Confirming this somewhat is the fact that on parallels, the crank assembly is almost...
