Well I spent some time in the garage with my girl lady night... First took all the plastics off, and looked for any hose / plastic damage - no sign of heat or melting. Next checked the coolant level in the radiator - filled to the brim, started leaking when the cap was loosened. Expansion tank is approximately at the "cold" level. Next checked the wimpy fan - no big gravel or rocks, but won't turn on its own for the first 5-10°. I get it through this sticky spot, and then it feels free, I don't feel a hang-up when the blades go by any particular spot. Finally I got to changing the oil. After warming the bike up (only for oil changes now, I swear to the BMW gods!!) I drain the oil. Darker than new, but not black. It has approximately 2,500 miles on this oil change. The oil is very thin (was Maxima Maxum4 10w-40). The magnetic drain plug has a thin coating of grime, but no visible shavings. A little background info: about 50 miles back I changed from the BMW aluminum skidplate to the Ricochet, and changed the oil filter (not oil). The BMW skidplate was banged up enough that it was difficult to get all the mounting points to match. The old oil filter also got a crease in it, causing it to leak. I note that the new oil filter which I installed already has a dimple despite of the Ricochet skid plate (thinking of ways to fill in their slot). I caught an oil sample as I drained the oil and sent that off today. Hopefully I'll hear back by the weekend. Filled her back up with Castrol 20w-50 4T motorcycle oil, and reinstalled the "old" filter. Starter her up.......... Normal racket, louder because the plastics are off, and then quiets down right away. Let her run for about 15 minutes. The ambient temperature was pretty much similar, although maybe I should look up a weather report. Kept one eye on the temp gauge, and the other on the cooling fan. After the gauge gets to half-way, neither of them move. Not a sound from the cam chain after the initial start-up, but I wasn't about to let things get hot. After about 5 minutes with the engine off I check the oil - it reads overfull, even though I only added 3 qts (capacity is listed at 3.1 qts). I'm not sure how to read that. Normal the oil being over-full is an indicator of a blown head-gasket, meaning coolant leaking into the the oil (correct?). But like a said, the coolant level looks fine, in the radiator and reservoir. On a carburated engine it could also be fuel filling the cylinder and getting into the oil, but I don't think the fuel injection would allow this to happen. Don't understand this one, but all I can figure is that not all the old oil drained. To be continued when I get the oil sample results.
