I have an 05 700 efi, this weekend we were riding down some steep hills and while comming down in low gear
I was hearing what sound like a belt whining from the front end. If you touch the gas the sound went away. Let off the gas still going down hill and the sound would come back. Is this a normal sound from the engine braking system or do I have a major problem going on with my front differential. I was the only one riding a polaris so nobody else had any idea. One last thing, does anyone else have an anoying rattle sound comming from underneath????

Thanks.
Jim

 

mine does that to. its the ebs working. i dont think its anything to be alarmed about. as far as the rattle check the rubber boot on the support mount for the exhaust up front it may be melted.

 

Thanks I'll take a look.
