I couldn't have said it any better! Although I have re-torqued the flywheel and have nearly 160 miles logged on the new WR450 I still have that lingering worry of breaking down in the middle of nowhere. My warranty is up in just a few days and I would like to see Yamaha take care of ALL WR's in or out of warranty. I'll feel more confident about the flywheel situation (with my bike) when I have logged 1,000 miles.

Dealer repaired as per instructions from a Yamaha representative who was there. Dealer states Yamaha feels it is being caused by jetting that is too lean, causing a backfire during e-start that shears the key. They said they rejetted the carb and installed a stronger woodruff key. The part number for the key on my receipt is 90280-03001-00. I'm curious about whether this is in fact a new part number compared to the old key. My receipt also shows they replaced the spark plug, part number CR8E, an NGK plug.
I don't know what they jetted my carb to but now it runs like crap on the low end. It ran great opened up on the dunes but it would not idle and wanted to die whenever I was coming to a stop. Furthermore, I could only start it with the cold choke even after extended periods of wide-open riding. (It was about 50-60 degrees up there, but I wouldn't think that is cold enough to require the cold choke after long riding).
On the other hand, I used the heck out of my e-start, way more than I did before the initial key break, and I've had no problems.
So, now I need to figure out my jetting to get that bad boy running like it was meant to.
