Gents, 07 1098 is making a whirring sound from the motor. Anyone else experience this? Sounds like beginning stages of an accessory going bad in a car, power steering or a/c pump, belts, idler pulley,etc. Stumped my local dealer as they listened with me. It has just under 3k, done a couple track days. Not abused. I Stethescoped all around idler and tensioner pulleys with covers off , but exhaust and bag-o-walnuts clutch make it hard to hear. Drained the oil, the normal slight bits that come out of all my other 8 ducs over the years at low mile or break-in oil changes. Removed dry slipper clutch. Same noise.Then right side case. Same noise.Then the gear to the transmission, to take it out of the equation. Same noise. All 1 step at a time, lighting it up in between with side cover temporarily in place to keep oil pressure. End bearing looks mint clean. Even removed oil pump. As it spun in my hand , seemed like it could be the culprit. Opened the pump halves up, O.K inside. Even took a chance starting it for 1 sec without pump, as I was sure that was gonna be it. Same whirring noise. Back together again, Just put 15 miles on it. No power loss, knocks, or ticks. Really sounds like my 81 Euro spec 850 lemans Gootsie with agostini timing gears. Tomorrow I will try waterpump removal and the left case. Track day next sunday and I want to sort it out by then or park it. Any ideas?
