Grinding , scraping noise from front sproket

[harrellscat]

I have 2008 GS. only 8K miles. Have a loud, high pitched scraping, grinding noise from primary drive/sprocket area. Increases in frequency of scraping and higher pitch with speed. I don't believe it is engine or clutch related. Noise is there even with the engine turned off and sounds like it varies directly with the speed of the bike.

I have had it to two dealers with no results. Mostly they say they can't hear it, but when they ride another Spyder thay can then tell the difference. It is to the point that I don't enjoy riding the machine.

Any ideas appreciated.

Thanks
Joe

UNK NOISE

OK you can hear this noise without the motor running but you are driving down the street/highway......you're gas mileage must be awesome......Seriously I think it's brake /rotor related....IMHO....Mike....:thumbup:

Sounds like a worn front sprocket/spine or the bolt that holds the sprocket is loose,?
But how do you get it to make the noise with the engine off, roll it back and forth,
In that case check your rear wheel bearings it will make the same noise if worn and sound like its coming fron the front, [Vibrates up the belt]

:shocked: And those 2 dealers couldn't find it?? :shocked: They need to get the wax cleaned out of their eyeglass-holders! :gaah:

Turn the engine off when at 60mph!!!!

Just curious - I gather that the latest models don't have the potential drive pulley troubles like the early ones, correct?

My bet is rear bearings shot due to original high belt tension. Best to just replace them all....

Tear the rear wheel down--- replace the bearings---- pull front sprocket and inspect splines---put it all back together and make sure front sprocket bolt is torqued to proper tension---- then make sure belt is proper tension too. Have you ever had the belt tensions readjusted (lowered) to the new spec?

Any good dealer would have done the above--- it ain't rocket science. Sounds like you'll need to either do it yourself of tell the dealer what needs to be done.

Correct: redesigned the front shaft (2011), lower belt tension (2010) and screw retightening torqe values (2009).

Shaft too eh Doc? I thought it was just the pulley.

Yup -- they increased the torque of the shaft bolt to 89 ft/lb........ you wanna use the blue loctite--- or better yet just replace the bolt with a new one that comes with the yellow thread lock on it.

If you don't want to pull the sprocket all the way out.. at least pull the bolt, mark the shaft and the sprocket with a sharpie in like 4 spots.... like an X that goes across the shaft and the sprocket. Then put the bike in gear and roll it forward until it stops...check the X mark and see if it has moved. Do the same thing but rolling backwards until it stops... don't be afraid to put some force into it. You're just trying to see if the sprocket will move any when the engine stops the shaft from moving. With my first bad sprocket it was very noticeable...didn't even have to mark it to see it move. Sometimes handy to have a friend do the rolling while you watch the sprocket for movement.
