I did the 1,000 mile oil change today, using the Amsoil 20-50w full synthetic I bought the other day online.
one thing I did notice when I took the drain plug out. there was some sludge caked on the top of the plug.
I also noticed that the oil that drained out was pretty black, especially for only 1k miles on it.
on other bikes/vehicles, if I couldn't see/read the marks or letters on the (metal) dipstick, I'd change the oil and filter....done this for years. same with bikes that have sight glasses to check oil level, if it looks dirty, then I'd change it no matter if it had the suggested miles on it or not.
anyway, I do believe the shifting is smoother now and the engine noise is less after this oil change.
I kinda wished now i'da changed it sooner....like at 200-300 miles.
