Did my 1st oil change used Motul 15-50 motor oil. Had problem with removing oil filter, Used claw type grip filter remover dented filter, STOP, bought 2 7/8 to 3 1/2 in filter wrench TOO BIG Oh my. Used my leather belt around filter with oil filter wrench, did the trick. Other item I was surprised at the "CRACK" or "POP" when loosened the oil plug. Oh rookie mistake forgot to fill oil filter with oil. Is this a big problem? I would think some of the oil from filling the crankcase slowly would trickle to the filter. Started her UP runs fine, put cardboard under TBA, got up this am NO LEAKS. Took my first ride yesterday after the oil change, wow seems to have more power, less vibration, and sounds very smooth. For me the 15-50 will be the way to go. I think the dealer used 10-40. Read on another thread $100 to $200 dealer charge for oil change. Plus I saved $50.00 for 6000 mile service.
