my dealer Changed mine out at 20,000 on their recommendation, but since I bought the prepaid maintenance plan from them, it was covered in the service. went with the SE Hi Performance Mixture. Cost to me zero dineros. BTW I bought the bike in Aug 2013 and purchased a 3 year maintenance package for 1500.00. Usually average 20k per year. So at 225.00 per service x 4 per year x 3 years I figured I'm 1200 ahead on this deal. After is over I'll be doing my own services, so IMHO the service plan is a great deal if you ride a lot. Also, all fluids are except the forks are synthetic at no extra charge.
Life is too short to put up with stupidity. Strive every day to educate someone, including yourself!
