Took my 2015 850 SP out for it’s second ride today and I noticed it’s developed a whine or whistle like sound between 2500 – 4000rpms. The sound is there in all gears, H, L, N, R, P. The sound is significantly louder when in gear, but it’s definitely still present in Neutral & Park. Sounds like it’s coming from under the handle bars. Any suggestions?
