    Yea, back then the metal fatigue hadn't even set in yet.. haha! I remember having a stripped cyl base bolt 15 years ago when the crank assembly was overhauled, it was fixed with a pretty bomb proof insert. Might have been wise to do all of them but they were fine back then. Anyway now the main bearings are worn, the engine sprocket splines are worn.. the pistons are at the wide end of the tolerance, with visual return marks at the bottom. Will probably be alright with next o.s. pistons, and a new set of rods. Running used rods with unknown age and milage is kind of asking for it, even if the bolts, bearings and bushings are new. He's gonna get to measure up the cams, tappets and all that too. And balance the whole rotating assembly including clutch basket. All engines breathed on by this guy are durable, smooth ,and reliable. Built after users requests of engine character. Used to prep racing tridents and bonnevilles for decades. I'm actually looking forward to the hours on the phone with the guy, he's great! 2-3000$ is what he usually takes for a complete teardown and rebuild, im doing most if not all assembly work myself, might have him button up the bottom end and cylinders though. He's always giving me a great hourly rate anyway.

    Gotta say I farmed out my 500's bottom end, did the rest myself years ago. They are amazing engines when rebuilt well. Mine was 60 thou over on the bores at one point. At least you could get good OEM spares then.

    Yea, im a good welder and decent mechanic, not a machinist in any way. That stuff is best left to the experts.

    Excellent! Autumn is a fab season. I hear Manegarm's 'Blot' when I think of it.
