I never bother with checking my transmission lube level. Nothing is leaking. There's no drip spots where the bike is parked. Transmission lube isn't under pressure and doesn't get consumed. I change the lube maybe every 20,000-25,000 miles ... take out a quart, put in a quart. The dipstick is pretty useless ... I can never see the lube level on the chrome stick.
Look at the parts diagram and the dipstick is no where near the cable to where they would rub together. .
I've been following this one closely and looking at every bike I can get my hands on. I just don't see how this is possible on a 2009 or 2010 bike.
