Wind pulsing noise

[justin1620]

Hey guys…I’ve noticed a new “wind”sounding or “pulsing” type noise while cruising coming from my sidewinder. I just changed the top gear so I looked in the chaincase again and the chaincase all looks fine. My track is pretty tight and skid wheels all seem fine. Not sure where else to look….

If it’s a rhythmic pumping noise it could be the rov cycling. If it comes and goes based on deceleration it could be the blow off valve. What year is your sled and when do you hear the noise.

My sleds a 2018…I hear it at cruising speeds 40-60 mph
