Interesting! however my problem is not just a whine, riders beside me have questionably commented about it. My 1st bike was a Seca750 and there was a normal yamaha whine to it. my 2nd bike is a BMW k100rt it also has a particular normal whine to it. But this Venture whine, drowns-out the sound of the engine, again this is only during normal decelerations while under engine compression. My angst concerns the lateral movement of the clutch basket that I am able to generate by simply moving the basket. I would suspect this probably generates the vibration that results in the sound I hear. Anyhow I will remove the clutch boss and basket so as I can have a better look at that bearing before I drop the engine and most likely end up changing that 'bearing'! I have the Yamaha service manual thanks to this web site, but I have been wondering if there are any Clymer or Haynes books for the Venture. I like working with these 2 other books because they take into account that I don't dabble in these areas of expertise all the time and will mention or note important side notes. If anyone does have these books I would be greatfull if they would send me the related chapters on engine removal/installation as well a engine/clutch overall or anything relevant to the matter. Of course being able to own one of these books would be even better. thank-you.

I have the same problem the drone occurs only when the clutch is completely out and I am decelerating under engine compression, check my post and tell me what you think. Also Check out this article in the tech section I believe. Pay particular attention to the clutch bearing pictures (Engine Removal and Clutch bearing Repair, by Freebird) I am of the opinion that these noises are not normal, and have to be properly addressed . I am an aircraft technician in the Canadian Forces and Some noises are NOT NORMAL and this is one of them.

Hi gang allow me to introduce myself, I just bought a new for me 1991 Venture Royale so my wife and I could go touring 2 up. The Venture only has 72,000km so my thought was uhm just broken in. My other steed is a BMW 1989 k100rt with 125,000 km, my wife just doesn't find it comfortable for long hauls so its gonna have to go. Anyhow back to the subject at hand. There is a whiney drone coming from the engine area. The sound occurs while riding, and occurs when I release the throttle and last until the engine revs are very low, it happens all the time at any speed and in all gears. I suspect something to do with the clutch. This evening I removed the presure plate the friction plates and clutch plates, all are within specs. I have not yet removed the basket however I did grasp it in my 2 hands and was able to slightly move it laterally forward backwards and up and down. Here is my question am I right to suspect that the bearing just behind the basket might be worn or damaged as any play in the basket (shaft) doesn't seem right. Maybe worn bearing, side play affected by the torque of the engine compression slowing down the bike? Check out this picture it was taken by Freebird and this is what he found behind his clutch basket notice the bearings, the cage is broken I suspect this could cause the severe noise I am experiencing. http://www.venturerider.org/engineremoval/images/815.jpg
