I am pretty sure I broke my woodruff key. Made a noise with the e-start and ran poorly after that. I took my bike back to Bert's Mega Mall in Covina, CA, where I bought it. Today I spoke with the service manager and he said they have had a couple of other bikes come in already with the key problem. He told me that Yamaha reps were there today to look at the couple bikes with key problems, mine included, to "check it out." Just thought you might be interested. By the way, for those who are interested, the production number of my bike is 1018.
