At >4k w/ +1 tooth does the bike run stronger?
Is that premise of variable cam timing?

Well it is all back together now and running just fine with its new throttle bodies....I did a sync check on the new TB yesterday and they all lined up perfectly which i imagine is how they came from Yamaha as the dealer wouldn't be able to figure that out.....

I am undecided on that, based on all the screwed up and loose stuff i found when i lifted up the tank I will never take MY bike there again...
What I don't want is a bill from yamaha for a throttle body.

I doubt they can get you for a screw up on the dealers part but if they knew you hypotheticaly had a hand in the issue it could cause trouble in the future.
Better to let sleeping dogs do what they do best. Glad it worked out and hope to see you in Canada and Eureka.

Yup, same thing happened to me first time I did it. I zip tied chain up top but neglected the crank sprocket. My bike never died or anything, and by the look of yours and your idle issue, maybe it was off 2 teeth or more?

I am still undecided on if i should go and tell them how they screwed up.....maybe i will go by there tomorrow.
What would YOU do?

It kind'a depends on which way you serendipitously happened to let the chain slide on the crank sprocket, right?
If you advanced the timing, as I suspect King Richard and the Skooter dude did, then it will idle poorly (at low rpm) but still run like a ***** ape at higher rpm. But if you ******** it (he he, I said ********) the bike would probably idle fine and dandy, but then ride like **** outta the gate.
And yeah. That's what VVT is. You intentionally ****** the timing at idle and then progressively advance it so the valves open sooner, at high rpms. BMW (autos) have been using VVT for some time now quite effectively. Even as far back as my 1995 BMW 325i sedan, it had Varios (VVT) on the intake valves. It's a real easy way to make a 2.5 liter NA engine produce >205 hp on regular fuel.

I would move on. You won't get any satisfaction out of it and they won't learn anything from it.
Just a waste of time.

Fred just so we are clear on this......it was neither Skoooter or myself who installed the cam incorrectly, not that i am naming names but the person who installed the cam has a name that sounds alot like Val.........
And Johhny if I dont say anything they will never learn from thier mistakes and some other FJR owner will get way more screwed than i did. There was an FJR parked in thier service dept when i picked mine up.

Let sleeping dogs lie Richard. Make sure you have the PAIR system capped to help keep that new throttle body clean, and just move on.
I'm telling you guys, allowing the Gen-II cam chain to accidentally droop and wind up one tooth off is WAY easier than you think. It doesn't actually skip a tooth during reassembly. It only droops on top of a few crank gear teeth and sorta falls back into place (one tooth off) as the tensioner is reinstalled.
I've done it myself, with the difference being that I caught my own mistake and fixed it myself. I spent an entire day playing with the FJR cam chain system to see how the mistake happens. You couldn't purposely design a better system for mis-timing cams. The motor was made to set time OUT of the bike, not IN the bike frame.

I'm with Ashe on leaving this alone Richard. The dealer will happily play the replace parts and charge Yamaha their flat rate game - no matter how much you try to educate them. The manufacturers effectively encourage this behaviour and the dealers have lots of overhead to cover every month.
However if it had been their mechanic who had mistimed your cam, that would be an entirely different discussion and a pretty loud one at that...

Gotta agree with everyone here Fairlaner, let sleeping dogs lie. ^Dave^ nailed it...unless you get a really good tech [or they can plug a scanner in], they are not diagnosing much these days. Keep changing parts until it's fixed. With the collective here, we have more knowledge than most any shop can ever hope for.

I disagree.
To not note the request of the customer, asked at least twice to the service department, to 'check the timing', post an 'at home' valve adjustment / cam removal propagates the idiocy.
If I was MamaYama, I'd be completely pissed off at the inadequacy / professionalism of my companies franchise. It cost me money, it cost reputation. Lack of reputation cost sales, loss of sales means... well, you get it.
Just today, if someone had mentioned an 'issue', not yet realized, the next two weeks of my professional life would be sooo much easier. I sure as hell wish that 'someone' had raised the flag. Now I have at least 120 hours x 3 FTE to correct the issue. :****:
So yes, let the local dealership know, ensure the service manager and technician are in attendance. Hold them respectably accountable, least they not learn the lesson so the next guy (without YES) has to pay for the 'experience' of their inexperience.
We as customers have certain responsibilities, too.
My .02 worth.

Not a chance in hell. Two teeth off and you're buying a new cylinder head. No way an FJR doesn't bend valves if the timing is 2 or more teeth off.
Richard, you need to cash in on your luck and buy a lottery ticket.

I haven't had a good laugh in a long time. Go ahead and walk into a dealership and tell the service manager that his experienced tech is incompetent, that you disassembled your FJR at home yourself and fixed the problem with the help of people on the internet. Be sure that the dealer knows that you read about this problem on the internet and used it for your diagnosis. Dealers just love to hear about problems you found or read about on the internet
D' I understand what you are saying, in a competent world this would be considered good feedback for continuous improvement in their shop. Unfortunately, I haven't found many shops that value this kind of feedback.

+1, Gunny; once again our Sir Alan is 100% correct, just let this one ride 'R'. I'm shocked at johnny80s answer though, I figured our Goombah would break their heads!!!I haven't had a good laugh in a long time.
