I purchased the 800EFI in December. I have 5 hours / 46 miles on this machine. This is my first Polaris & I'm sure I'll love it, but I do have a question. Lately I have noticed a knocking sound coming from the bottom right hand side of the motor. I'm not sure if this is something that is progressively getting worse or if I'm just paying more attention to it. However, this noise becomes more dominant after the ATV is warmed up, and it sounds like it's coming out of the water pump. The knocking can be heard well over the exhaust and engine. When you do increase the RPMs it's not nearly as prominent, but if you listen close you can still hear it. I ask my dealer this over the phone and he keeps telling me this is normal but I'm not convinced. I stopped by another dealer a few days ago and started up an 800EFI they had on the showroom floor and let it run for a while and never heard anything. Does anyone know if this is normal and should I have it looked at?[img]i/expressions/face-icon-small-confused.gif[/img]

 

my 05 700 efi has done that from day one. they told me it was the fuel injection making that noise and it was normal. mine only does it at an idle.

 

Mines does it at idle and has done it since day one.

 

No this is totally normal I have an SP800 and it does the same thing. It sounds like it's going to blow a rod or something but your ok, run the hell out of it!! I know I brought mine back to the dealer the same as you and they said it's A ok. I have 550 miles on mine & I run the **** out of it. Just enjoy it like I am mine & DON'T worry!!

 

normal

something else you might hear is the EBS, when you slow down and it sounds like you have rocks in your transmition, its just the EBS belt slapping tought agaisnt the pullys

 

are you sure it's not just the typical/normal clutch slap sound that comes at low speeds when giving it throttle on/off. if so it's just the clutch/drive where the belt/clutch cover is.

 

I don't think it's the clutch because I can hear it while the machine is in Park. The clacking noise only gets loud after the machine is warmed up. Just doesn't sound normal but if you guys think it is, then I'll let it ride.

 

if you could pinpoint were the sound is we might be able to help you a little more.

 

It sounds like its coming from the water pump, on the bottom right hand side of the engine.

 

i think you should have it checked i dont think it is normal to hear it over the exhaust and the engine
