As long as you're not planning gear drives, .005 is quite good these days. 2002 was the last year for the "good" bottom end. Cranks were pretty good prior to 2007 when they did a major lightening to the wheels. I don't have a clear answer but I don't think your runout is excessive. From my perspective, I would want a seasoned professional going through that cam plate and oil pump to verify everything gets assembled and checked properly. I've never seen what might result from blatant lack of oil pump alignment, but I suppose the possibility exists that if the pump was grossly misaligned, the end result could be this type of failure....

I got .007 run out on a 08 had it from 10,000 miles the first time I took it apart to do Torrington inner bearing. Had cam chest apart 5 times changing cams,zippers dual piston chain tensioners 255 cams and going back to stock cams and just week before last put as set of the new 2014 cams and new lifters and it has 30,000 miles on it now, oil pressure is spot on with a mechanical oil pressure gauge and smooth as glass at all speeds and rpm's. With .005 you are fine. That had nothing to do with your oil pump.

Crank run out is .005.....said everything else looks good and solid excluding the inner pump ring. Anyone with specs on run out? Hearing different things form different folks...and cannot find a specific number in the service manual.....
Hate to rebuild a motor with 31,000 on it.....tempted to throw stock cams back in it replace the oil pump again and hope for the best.....
Knowledgeable input truly appreciated!

have they checked that the camplate is not warped or incapable of being properly torqued down?

well if your crank is true in runout, then you have an issue with something else. so yeah I'd check threads, check stretch on cam plate bolts too. I'm sure they know this already if they work on bikes but the 4 bolts holding the oil pump to the cam plate need to be loose when reassembling. Keep them loose, torque down the cam plate, then rotate the wheel back and forth a few times so the oil pump finds it's natural center on the crankshaft then torque down the oil pump bolts.

If I remember correctly you need a special tool for this It is the tappet block alignment stud tool gizzy and is about 6 bucks. You use a couple of them and while the bike is in 5th gear you rotate the wheel while tightening in small increments until tight.
On my old 04 I used 4 of them the dealer mechanic loaned me ! Previous to doing this I had a lot of blowby and after had almost none.
