I know nothing of Roseville yamaha. I know about engines. There is too much that doesn't add up for everything that has been said to be true. Zac may be the greatest guy in the world, but even Johnny golden socket screws up once in a while.
30% past the valves in a leak down test is an engine that won't hardly run, and I see no place that there was a complaint of that.
Guides worn out badly enough to cause a 30% leak down loss would definitely leak oil into one of the cylinders at least, probably more as it sits over night and cause one hell of a plume of oil smoke when started the next day. I see no complaint of that.
Those are two very basic things that would have been definite symptoms of the described malady. Especially if there was oil in the exhaust.
I understand that those of you that know these guys personally will and have taken offense, because I have questioned their abilities and their course of action. As professional techs they should be more than used to it, and have some very good answers if they are above the table. God knows I have been in front of the firing squad enough times my self.
The problem I see here is that a guy takes his scoot in for a routine valve adjustment and is now getting guides replaced and only the exhaust valves replaced...so is this engine really that poorly built that it wears out the exhaust valve guides, on a shim bucket none the less, without causing the same problem on the intake side? Sorry, everything about this indicates someone didn't get everything lined up, bumped the starter and bent the valves. How do I know? I have done the same damn thing probably 25 times. Does that have anything to do with whether or not I am a hell of a guy or a run of the mill asshole? Nope. It just means I made a mistake. The part that burns my ass is when someone makes an honest mistake and isn't so honest about it.
So, since I am the FNG here, I will explain it this way. I am trying to save the OP some funds. He needs to start asking the right questions. I.E. I asked for a valve adjustment and a new tensioner, why the sam hell am I paying half the price to put new valve guides in? I didn't ask for that, and I don't want to pay for any of it. And.. If the exhaust guides are worn out so bad the engine won't hold compression how come it ran so good?
So, I am the bad guy here, its ok. I am used to it. I am married. :lol:

Sorry if they are your friends and it burns you that I question their course of action. Saying that there is zero percent chance of that because you are acquainted with them only puts your own credibility in question. People are people. Being a tech is a bitch of a job. Shit goes wrong in an instant, usually when you think everything goes right. If you haven't slung iron professionally, you have no idea how things work in a flat rate shop, or when you have to worry about a dumbass service writer lying to your customers, a service manager that can't tell a flat washer from a u-joint or an owner who wants you to take his piss test for him. Being around mechanics and being a mechanic are two entirely different things. Being around a mechanic usually means you are getting charged more for slowing him down and annoying him. (hint, hint).Personally knowing the OP and the Service Manager in question, I'd say there is just about a ZERO percent chance of that. I don't make a living wrenching, but know my way around wrenches, have always done most of my own motorcycle wrenching, and have been riding almost 45 years now. So, I've been around a few mechanics and motorcycle dealerships. I've never found one with as good a service department as Roseville Yamaha, nor many people that are more honest AND helpful than Zac.
