My '07 650L has 700 miles on it. I've changed the oil&filter twice. Did dave's mods, swapped to MT-21's and 14/48 gearing - what wonders those did for this fatty mcgee. One thing I notice is that it seems like my shifting gets clunkier after riding about 15-20 minutes and the engine is fully warmed up. I don't think it's running too hot, I've IR-gunned the oil through the dipstick spout and have never registered more than 200 F. Almost feels like the oil gets hot and runny and doesn't smooth the shifting the way it does when cold and thicker. I'm running Honda GN-4 10-40w in San Diego where it is never above 90 or below 65 F ambient. Is this normal or anything you've experienced? I'm easy on the girl and given the low mileage I find it hard to believe it's a clutch issue. Any thoughts?
