About time. Glad to see you have her back together!  To bad about the possibility of a piston slap.    Do you think you might be with timing and its pinging?   Just thinking out loud here.  I'm sure you have thought of all of that

Long story short, this is the second build of this engine, the first one overheated when it blew the head gasket (no clue why). The first build ran perfect before it overheated. Tore the engine down again, lightly sanded scoring off the pistons, rehoned the sleeves, and replaced all the gaskets. Sanding and honing mustve removed just enough material on one piston. No head leaks but ticking now. All evidence points to piston slap. Loud when cold, quieter when hot. Checked cam clocking, thats all good. Engine feels normal and doesnt blow smoke. Just has that damn tick.

The only other possibility is valve clearance. It was set first build but with valves and seats freshly cut I suppose I could be out of spec already. Its on my list to check after break in oil change.

Ill be lurking for ride!

Welcome back.  Was going to ask if w/turbo but looked at the pic and answered that question.  Still have the noise without boost?  would think that would exacerbate the noise if its piston slap.  My dad has a mid 2000's chevy pu that has had piston slap when cold from when it was new and hasnt caused any issues.   
Live long and prosper \V/

Im sure it exists on power but it quickly disappears behind engine noise even under light engine load :)

Between the Mun and a new baby (congrats, BTW!), how do you find time for a Turbo engine project?   :|)
It's about taking in the most corners to your destination, not about the shortest, quickest route.

Have you tried running a little bit of ATF in the oil for a little while? This can help break in parts. I have good luck using that on engine builds before although not on a bike.

Congrats!
