Well this past weekend I've been thinking man it's been awhile since I had the oil changed. I clean and lube the chain often as required. Being my first motorcycle I would rather the shop take care of most the stuff but I'm not afraid of oil. Anyways, this actually happened Sunday i was riding the bike to work then the oil stated flashing on me. thought I post anyways. Motorcycle shops are closed on Sundays here, luckily O'Reily had the oil and filter. Mobil 1 10w40 synthetic was on sale at 8.99/ bottle. Not bad and filter was about 15. I bought a kn204 filter. Easy to take off next time with its design. Since the shops were closed. I for gone the new crush washer for the plug. But I've ridden the bike 100mi since Sunday and it's all dry. On the next change though I plan on using a magnetic plug so I'll buy a few crush washers and stock up on them. Manual says 2.2qts. I bought 3qts and 2 was plenty enough to get the job done. Bike shifts like a champ again. Saturday on the way home the bike was having issues finding 3rd/2nd and 1st gear. I guess the oil really does play a big role in this bike. I haven't had any issues since at any gear/ speed.
