It turns out that sometime in the past, someone stripped the oil plug and they had to have the case tapped for a bigger bolt. I can't use a standard one but a local motorcycle mechanic (and the dealer) said I could use the teflon tape method to fix it up, so I am going to try that out tonight.
My clymers book says to use 800ml of fluid in the tranny. If I put that much in, my sight-window is completely covered. On my kids kx250f the sight-window has hash-marks about halfway up, so, how much do you guys use?
