Anyone else have an exhaust "whistle" (or squeak) Seems to be loudest when at idle and esp. at shutdown. Any ideas whats causing it?
Thanks for all info.

 

i have no such sound coming from my grizzly. maybe it is an exhaust leak? good luck finding out what it is and let us know what it is when you descover it.

I think I know what your talking about at shut down. Mine has a couple of hard raddles and then a pretty load squeel. I don't know what it is but just figured it was the clutch coming up againest the belt. But like you say at first I thought it was the exhust but I don't think so now.

 

ye i have the same thing. it does not happen all the time though, only when i am riin it hard and shut down. It is not a problem i would just like to know what it i so i can explain it. I thought is might be because the engine is so big it has some kind of "rundown" or something. probably not though, that is what i tell myself. lol.

 

Yes, I know exactly what you are talking about. It coincidently started to happed just after I got the belt wet. So I started to get kinda worried and took the cover off the transmission to make sure the was nothing wrong. When I did all of this, and found nothing to be wrong, but it still making this terribly annoying sound, i had to investigate. After a couple of minutes trying to pinpiont the source, I notices that a bolt was holding the muffler on was loose. I haven't had time look further into this, but I plan on looking more into it this weekend.

 

My Grizz 660 runs great but I have also noticed a bit of a screetch when shutting it off (not all the time though). I haven't noticed anything while in idle but if I give it a high rev while in park, I sometimes hear that too. I don't think its a big deal but if anyone finds out different let me know.
