I was not going to post until I had more data, but to answer some of the well stated questions, I'll add some more info here.
Fred W. and Charismatic asked about performance/running right:
I don't believe break in method would have taken this long to show up some issue if the break in method was abusive. Likewise I don't believe oil choice had much, if anything to do with this. I do change the oil regularly after all. Same for filter, etc. Let's not devolve into arguments over personal preferences on oil, change intervals or break in methods. None of those can be proven to have been part of this issue at this point in time.
Fred W. and Charismatic asked about performance/running right:
When I rode it into the shop, my only issue was the cam chain noise. Riding it out of the shop, the idle wouldn't stay even and it bogs under WOT. I was told, (and already knew), that the plugs and air filter are due for replacement. I think that some or all of this is due to having those items compomised and the O2 sensor actually being good now and the ECU attempting to deal with the situation. Before with the dead O2, it was just running on canned maps, much like a PC III would. Note that Skooter's bike isn't using the O2 sensor, so that may acutally be in his favor.I was under the impression that the shop couldn't get the proper exhaust numbers from your bike -- and hence the "engine worn-out" conclusion? Not, that you had a performance complaint....
Well put, and I agree. I didn't go to Yamaha saying I wanted a rebuild or new motor, I went asking "what's going on with my bike?" The warranty specifically does not cover low compression due to worn rings. The debate, and it can be a heated one, is wether this is normal wear or premature wear. If your brake pads wore out in 30k, it would be normal wear, if perhaps faster than some other riders. If they wore out in 1k or even 5k, you would wonder what caused that because it would be considered by most to be premature wear. Same kind of thing here, but the burden is on me to prove what condition or defective part caused the premature wear.I think the warranty is for defects in material and workmanship -- not normal wear & tear? Usually, that means a part fails. I don't think it can be construed to provide you with a new/like-new bike for the term of the warranty.
Noted above, just the cam chain noise. Dealer says an irratic idle led them to the bad O2 sensor, (and diagnostic codes, I believe).What was your initial running/riding performance complaint?
I hope that is true, and am trying to do what I can to see if things will improve.I am not yet convinced your FJR is 'dead'. Especially since you report no smoke, oil consumption, or power loss.
Thanks.Good luck -- I hope you get it all resolved (to your satisfaction).
