YOC came recommended to me by Dave Hicks (aka Turbodave98), who has many years of good experience with the owner and service department. They took my eff'ed up previous tick repair from another dealer, (who I will comment about in another post) and carefully diagnosed and fixed all of the problems that the previous shop caused or failed to properly address.
Initially they were a little hesitant to go back into someone elses repair knowing there were issues, but after listening to my dilema, recieved the bike from me within 2 days.
While my bike was in the shop, the owner Jay would call me with updates on progress of the diagnosis, which I thought was a nice touch. They were very thorough with their diagnosis of the complete top end of my engine. To date the engine has been running very well.
As part of diagnosing/fixing my bike, Yamaha of Cucamongo also used half size incremental shims to set all valve clearances perfect, a leak down test and complete EGA check on all cylinders to verify the condition of the engine.
IMO, YOC are the standard that many others fail to follow. They are also more than 400 miles each way from my home, but worth every mile.
This company is 5 star Yamaha only dealership, with seasoned mature technicians (no kids wrenching on bikes) and I highly recommend them to anyone who is near enough to take advantage of their services.

Here is a list of what was found and repaired, which was not made any easier for them, as the previous dealer had not filled any warranty paperwork with Yamaha.
3 valves were near maximum clearance
Valve cover gasket reused, laden with goop
#4 spark plug high tension lead was not connected to spark plug properly producing an audible high voltage arc and intermitent ignition failure.
Thermostat housing thread stripped out with no bolt present. Housing was just sitting loose, rattling around
TBS way out of spec.
Exhaust header bolts were over torqued which resulted in all brackets being bent.
No oil change after cylinder head replacement.
