Hey MPLiner,
Glad to hear your situation has improved and repairs are on the way...it certainly sounds like we have the same problem.
Unfortunately I'm not necessarily convinced this will be the end of it. On the Raider thread I posted about similar lifter problems they had with their 113ci engines, the question came up as to what damage might have been done to other parts of the engine. That clacking noise we heard is metal on metal which could undoubtedly damage or cause excessive wear to other parts. I'm no mechanic, but they were saying to be sure your service department checks the cams, rods, valves, or any other parts that might have been damaged or worn due to lack of lubrication caused by the lifter problem. Of course these are things that may not show up for several years when the bike is no longer under warranty!
Now that our problem has been clarified and help is on the way, the worry I had is gradually turning into more of a pissed off kind of thing. I mean...you buy a brand new expensive bike that is supposed to be "bullet proof" and can't even go 5,000 miles before some major problem comes up? I guess I can understand the newly developed 113ci engine in '06 might have some glitches at first, and since my bike is an '07 it could fall into this category. But your bike is an '09! Even though it seems most of the 113ci engines don't have this problem, you'd still think after 4 years of production Yamaha would have fixed this problem and service departments would be aware of the situation.
This has certainly shaken my confidence in Yamaha and their quality control. When I purchased the bike my dealer said I should get 200,000 miles before any major work would be necessary. While some of this was undoubtedly BS, the design and quality of the engine does lead one to believe it should be very reliable and last a long time. Let's hope this is the case, and that after our lifter problems are fixed we'll have many trouble free years flying like the wind.
To infinity and beyond!
