I rode the sled for the first time this year last weekend. I rode about 80 miles, and was noticing a whining noise on acceleration. I can hear it on the sled but Its very noticible and gets kind of loud when behind it listening for it. It gets louder and louder with speed. I also noticed on very sharp turns it feels like my track is binding. Any insight on where to start to look? The sled has reverse, and has brand new chaincase bearings. Its an 03 ZL800 esr. The noise is similar to the deceleration noise but more high pitched.
