I hear ya. Being at the duc sites to check out the dependability of the product is a 50/50 shot. An example would be reading a 999 stalling at lights. Dealer level mechanic says he's seen more of the same model having the same problem. So from going to work and back, it stalled-out 20 times on average. Mech went thru it and it stalls one in every 20 less. Any bike you've owned ever stall? Didn't think so. That's unacceptable in my book if not flat out dangerous. Vo/Reg's taking a shit early is another. Electronic glitches. Not for me. I'm too spoiled owning Japanese brands.
No matter how you look at it, the flash would have placed more fuel at certain X to Y points, but for it to be lean at euro emission levels, has no effect on the cylinder wall finish. That's what I'm looking at. Is this the latest nikasil coating finish like the 14 has? Shit's bulletproof.
The exhaust can't effect oil consumption. Only thing I can point to is maybe an aftermarket air cleaner feeding larger microns at it. Probably one of the new camera scopes that can snake thru the plug hole, video the cylinder via a phone app?
The handy dandy leak down tool for that fleet you own is well spent. The cam-scope for the general look see. More like join the club and tool up you wanna play with these things. The all-in-house short of machine work. That's how I have to play it. I just bought a special tool for the HD. The rest I had to meguyveer, and the job is done already having the tools like a many pullers when I had to work on cars. Came in handy for this job.
I didn't catch if others were finding theirs too-used oil when new? Both beaters and book did you ask? A parts page may show a different ring supplier [if shows] that began with your model? Back to the nika and scope the finish. Unless they can prove the oil consumption is normal when new.
I mean, even going up to 4k just in shifting alone is not over the 6k limit just a few hundred miles later. But to rev at 9 or 10k and say fuck it, I'm committed to this corner already, with only 20 mile on the speedo? There is your oil loss to point to. But booked? You might have a case... if the beaters admit it, the books' match yours in oil loss... can't be.
Kind of see you have to do the work for them? Have to bring some evidence to prove something is not right. A guide seal would be easy to spot. The sits overnight, some valve is open and drops oil on top of the piston, or one is closed and still drips then is washed off eventually. That's morning start. So guides/seals are not it. This points to the rings.
