I have a 2010 Outlander 800R max that sounds like a valve clearance needs to be adjusted. The mechanic is saying he needs to strip down the engine, check the timing chain, the firing order, etc, etc just to check the valve clearance so I will just do it myself.

I have done it on many cars and bikes so somebody please tell me the gap size and where to set the correct position of the engine to adjust each valve.

Many thanks

 

All the twins 500,650,800 are done the same way.
Looks like taking the plastic off is the only hard part.

 

Wow! Thank you very much

You have made my day.

 

Hardest part of doing the valves on the outlanders (2015 at least) is getting to them. Once you're in there, it's easy as pie. Have lots of bandages on hand for the busted knuckles and an extendable magnet for dropped bolts LOL.

 

Thanks guys. I have noticed that when I start up the engine sounds good but by the time the cooling fan cuts in the tap tap is obvious along with a lot of other slight knocks, gear noise etc. Is this normal for a Rotax engine? All my Honda bikes etc have no engine noise at all.

The first thing I will do will be to change the oil as I suspect it is no good, possibly overheated. Then if I can still hear the tap tap I will adjust the valve clearances. Or maybe just do it anyway.

 

If you could post a sound file of it, video or whatever, it would make it easier to tell. They aren't the quiestest of engines. About on par with Polaris I believe in terms of knocking / pinging sounds.

 

406 and 604 Rotax engines we had in the old ATK dirt bikes were had were a little noisy,can't judge on Can-Ams between Polaris atvs,but nothing held a candle to engine noise the old Cannondale 440 made. Hated to even hear these things crank up and idle even straight out of the crate.

 

Thanks I will try. My internet connection is awful but I should be able to upload enough.

I don't have anything to compare with here as I have the only big ATV for over 100 miles.

 

OK guys I made a short movie. The tap tap tao and knock knock seem like they are louder in real life than in the video but please listen and let me know what you think. I don't think I can post images or videos yet so I have put the video on my server and will put a link to it at the end of this message if it is allowed.

Sounds the same as this guys 800. Must be just the way it is. I ride with a friend with a 2009 800 outty but I just never really paid attention.
