I've only got 80 miles on my new 800 and the motor has a knocking noise at idle. Anyone else notice this?


Thanks,


Michael

 

maby the valves ticking, theyre susposed to be ajusted after the first 4 - 6 hours of riding the quad

 

The noise is not from the valves, it is definitely a knocking noise and not a ticking noise...

 

its probally not somthing good then, i would bring it to the dealer and get everythin checked out but a sportsman owner could probally answer the question better

 

hey I saw a brand new 800 with 4 miles on it. Engine locked up solid. Get it checked out right away there may be an issue!

 

injectors, mine does it too

 

put a heavy oil in it take it to the dealer on a rainy day and trade it in for something better

 

wont be the valves, they are non adjustable. They use hydraulic lifters. Now about the knock, try running a tank of ethanol supreme fuel, they were calibrated in minnisota, all ethanol state. Had some issues that a tank here and there of ethanol fuel eliminated the knock issue
.

 

my 05 700 does the samething from day one. dealer says its the injecters on the efi making that noise. i have 250 miles on mine now and i run the hell out of it and its still running great. almost every one on here with the efi will tell you the same thing, but if your still worried take it in and let them look at it

 

My 800 has only 10 hours on it, and has done this since day one. It seems like after the engine warms slightly that the knock becomes very loud at idle. When you rev up the engine it doesn't sound as bad but as soon as you let off and the rpms come down it sounds awful again. If yours shares the same knock as mine then the source of the knock should be around the water pump on the bottom right hand side of the engine. I posted the same kind of thread a couple of months ago and got the same response that you've gotten. Some people think it's normal and some don't. I don't know what to do either. I love the machine but I want the knock to go away. If you some how find out how to get rid of it, please let me know.
