a) It doesn't tick over as reliably. Even when holding it on part throttle it will sometimes just 'pop' and die. Never did this before the rebuild.
Sometimes (but not all the time) When trying to start it, it won't kick all the way through the stroke, but stops half way as though I've come up against compression again.
Bear in mind that I've had the bike for 18 months so know it quite well, and these things didn't happen before the rebuild.
Only thing I can think of is that originally I didn't change to YZ timing until the bike was 6 months old (and therefore well run in). I've set it up with YZ timing with the new piston, so maybe it will settle down when I've done a few meetings?

It starts easier now and stalls less...

New gaskets - check
torque wrench used at build-up - check
Ring end gap done - new rings, ends positioned as per the manual
Valve shims at spec - check
No leakage at carb junction or aitrbox - carb wasn't removed, just disconnected from head. Seems to be back in place OK
It seems fine when it's running, it's just these two little things that make me a bit nervous!!

Can this explain your lean condition?
As for the weird compression I am experiencing something along that line. As SFO said the break- in may have something to do with it. My compression seems to be getting better the more I ride ( I have about 8 hours on the new piston / rings ) If your valves are well set and timed and the valve caps are properly torqued as Thronco mentioned I would not worry.
Take care and good luck. Let us know what happens.
