After having my 07 for five months and adding 4,000 miles to the odometer(9,500 total miles) I got her up one the lift for a little TLC and bolt on goodies One being new chain and sprockets. When I got to the drive sprocket I noticed some red dust Than when I went to take the nut off it was way to easy to loosen . ( I have done many sprockets over the years.) Seen this before on some Yamaha's a bunch came off the line with incorrect Tq values. My splines look fine never heard any noise I think every thing will be fine. I am not 100% if the 1st owner changed the drive sprocket . So could or could not be a factory issue,If I did not take some time show the bike some love this would have been a costly repair job. Any one else seen or had this issue?
