I ride my Viffer a lot differently than my Ridgeline--just saying.
It may be a market issue for motorcycles. They don't have to warranty their bikes longer than they do which raises the question, "why does BMW warrant their bikes for 3 years"? Heck if I know.
2 year warranty over here and 3 for the vfr1200.
I can't see an over heat causing oil usage, any damage would be more pronounced like a blown head gasket or warped cylinder head for example. in which case it would probably over heat again or you'd have oil in the water or water in the oil.
You say you have fully synth oil, has the bike always been run on this ?, these engines just need semi synthetic oil, one of the problems fully synth can cause is bore glazing, this would cause higher than normal oil consumption, it can be hard to get it back without having the bores honed which you wouldn't do as it involves a complete engine strip on these bikes.
I don't want and we don't need i'm sure to get into a big oil debate as that has caused many issues on many forums. but general consensus is that if using fully synth you do a good few thousand miles on semi synth to let the rings really bed in. even after that fully synth isn't really necessary as good quality semi is all the bike needs for a long life (with regular changes)..
I'm not a fan of fully synth as the extra expense imo isn't worth it, I also own an MT10 (FZ10) and Yamaha state to use fully synth. When i bought it (with 700 miles) a dealer had put semi in and the gearbox was very clunky, I changed to the recommended fully synth and it smoothed the gear clunk out, But in the next 2000 miles it used about 0.4 of a litre, I wouldn't expect that on a new bike. I ride that one hard which can help ring bedding even on fully synth but it maybe that it will now always use some oil between changes.
If what I've said is the case with yours then there's a good chance that the oil consumption won't go up so at least you'll be able to work out mileages to top up to keep on top of it.
To keep you coming back to BMW dealers to get 6,000 mile service stamp in the book
Bought a brand new fireblade a few years ago.. The bike lasted 3 weeks before I took the engine apart... result was 143bhp at the wheel.. had the bike 7 years before I sold it.. I don't get bikes for warranty.. that's a car drivers mentality lol
If you pull plugs you might be able to tell which cylinder is burning oil. As far as compression tests, i have seen good compression rings giving good compression and weak oil rings burning oil so a compression test may not tell all.
