Engine Tear down, What do you think?
Well I couldn't help it, I woke up early this morning so I could get more then just an hours work done on the engine tear down. from what I have seen, the guy was BSing, the motor doesn't look like it was rebuilt 18,000 miles ago. but I could be wrong, the good news is I don't care. for the price I paid I was expecting the motor to not run at all!! hopefully the pics work, let me know what you guys think,
What tool do I need to messure the cylinders to see what size they are? it supposedly has a 95 kit on it. and I would think I need to know for sure when I go to get parts for this motor if I decide to put it back together.
this motor is from a 2000 Fat Boy.

There's about a quarter of an inch between the bore of a 88" and a 95". I would think just about any ruler would do. I'd have a machine shop, or someone with the right cylinder bore guage do the measurements when it comes to buying new rings or pistons.

Let me see if I understand this...you're tearing an engine down and rebuilding it but you don't know what kind of tool is used to measure the cylinders? Sounds like you're in over your head already.

From the pics, you have a little too much carbon buildup on your pistons and heads for only having 18k on the build, and it looks like youve been using oil in one cylinder. Cylinder wear looks about right as you can still see the honing swirls. How did the wrist pins, bushings and piston skirts look?
To properly check runout and cylinder taper, you need torque plates and an inside mic. If youre considering reusing the barrels, send them out to a shop and have them bored .010 or .020 over and buy new pistons and dont waste your time micing the mothers. If you think you can get away with honing them, think again. You'll only get about 5k before the piston slap drives you crazy.
