About two months ago, my ‘Jammer developed an occasional howl that was not related to engine speed, more like road or wind speed. At first I blamed it on road surface as the howl at first came and went. As the miles piled on the howl became more constant and louder and I continued to elevate probable causes until I noticed the high mileage Metzler Lazertec sport front tire has fletching shaped center tread blocks that are starting to protrude a little higher than the rest of the tread. I am sure this has set up the harmonic vibration bring the howl to my fairing. I tried adjusting the tp up and down some with little improvement. I do pre-ride pressure checks with my little "Slime" gage so improper tp is not the issue. I began running sport tires on the front years ago to help with the higher traction requirements of the front and a touring tire on the rear. Front and rear have generally worn close to the same rate. Looks as if I will be replacing the front with a different model and/or brand of sport tire before it’s time.

Do you have vents in the windshield? Are they open? I find that I get a howl at certain speeds if the vents are closed. It's an air pressure thing.1980 XS850SG - Sold

Something to think about is that you hear much more from the engine with a Jammer. Make sure that all is well that way. First time I rode with a jammer I thought me motor was about to come apart. Many noises will tranfer from one place to another. It is entirely possible that you could be hearing anything from a bad front axle bearing to a low lubrication on your middle drive.

Proof will be in the puddin'
Originally posted by je2wheeler View PostAll very true, wind noise goes down and engine noise goes up. However, I replaced the front wheel bearings during the restore and the middle and final drive are checked monthly This noise was not there for the first several months after I added the 'Jammer, the noise coinsided with tire ware and the howling is still there with clutch in and engine cut at a 60mph coast.

what you need is a bro with an XS11 (or an XS650/750/850, it's the same front wheel) that will swap front wheels with you for a day or so. If the noise moves to buddy's bike, you'll know for sure.Fred Hill, S'toon
