Could you please post the engine size of your Bayou so we can add it to the thread title. You can get to the rocker arms through acces holes underneath cover plates on the front and rear of the head. On the side, there is a round cover that allows you access to the camshaft. I think you can pull the rocker shafts out from behind that cover as well, after that, you should be able to remove the rockers from the holes at the front and rear of the head. It is kind of a pain in the as* that Kawasaki apparently didn't see it necessary to just use a regular valve cover, but you can get to the parts without completely tearing down the motor. I imagine that you will want to remove the fenders and fuel tank to make access easier.

I have access to the rocker arms through those covers but I can't seem to get it out. The rocker for the intake is very loose even when adjusted down and when the valve rises it slaps the rocker. It's very loud. The exhaust side is good and the thing runs OK. Starts good, idles good, runs good (but slow, good for the wife) but that rocker is slapping bad. I assume this will wear out the valve or the rocker pretty quickly. Would the rocker possibly be broken off inside. It's so damn hard to see inside even with the body and tank off. Really don't want to take the motor out. I'm new to the repair of ATV's (and four strokes) but this think really isn't worth paying to have fixed. In reguards to the cam cover. Is this the timing chain I'm looking at in there? If I remove that to get to the screws behind the sproket that I am assuming are what's holding in the rocker am I gonna have to retime this thing? As for the engine size, hosestly and stupidly I don't know. Bought it off a friend of a friend for next to nothing for my wife as she is new to the ATV world. I'm new to ATV's as well. I've been riding Honda 250 bikes since I was a kid (and road bikes since I was 17). Couldn't teach the wife how to ride a motorcycle so four wheels and an auto clutch was a good choice. No decals left. He said it was a 300 but I really don't think so. It's really got buttkiss for power, and what's up with the worthless 1st and for that matter 2nd gear? Call me dumb but is the size stamped somewhere? I know they made a 220 and a 300 in 2000.

Yes, the cam and probably rocker shaft access should be behind the timing gear. If you put marks on the chain and sprocket before you take it apart, you can line them back up when you put it back together. You need to be sure to not let the chain come off of the crank, or make marks on the chain and sprocket down there for reference when you put it back together.

Thanks man and as for my stupid question about the engine size? If I need a new rocker or cam I'll need to know the engine size. Thanks again for your help.

      Have you ever been on the trail and your tire valve goes bad. No way to break down the wheel and replace it. A lot of you probably know about this already i had heard of it but never used one. Just punch out the old one insert and tighten down the nut
       

       

       

       
      So far it has worked very well.

      Anyone know what this thing is ?

      I've never done this before but after reading a few thread I decided to check my valves for the first time and to my surprise it was much easier than I thought.
      My bike is a 2005 Sp 500 HO.
      I first pulled the seat and the right side panel off, and that's it! It wasn't too bad to get at.
      Next I pulled the spark plug out and removed both the head cover ( 8-8mm bolts)
      [ATTACH]1021[/ATTACH]
      then the side cam cover (5-8mm bolts).
      [ATTACH]1023[/ATTACH]
      Also remove the plug in the recoil cover (14mm bolt) to see the timming marks.
      [ATTACH]1022[/ATTACH]
      Next I turned the engine over with the pull cord untill it was at TDC of the compression stroke.
      The best was to tell that your at TDC of the compression stroke is to rotate the engine until the
      timing marks are parallel to rocker cover gasket surface.
      The cam sprocket locating pin will be facing upward directly in line with the crankshaft to camshaft center line.
      Now fine adjust by looking into the timing hole in the recoil cover and line up the upside down "T" on
      the flywheel into the center of the hole.
      [ATTACH]1023[/ATTACH]
      Now using a feeler gauge, slide the .006" (.15mm)blade between the top of the valve and the bottom of the adjuster and adjust accordingly
      [ATTACH]1024[/ATTACH]
      [ATTACH]1025[/ATTACH]
      To adjust, Loosen the locknut (10mm) and check clearance with a feeler guage. Clearance should be .006" (.15mm) for both, intake and exhaust valves. Turn the adjuster with a stubby flat blade screwdriver untill the proper clearance is achieved then tighten the locknut (5.8-7.2 ft. lbs) while holding the adjuster in place with the screwdriver. Re-check the clearance with the feeler guage one last time and re-assemble the covers (72 in.lbs) and plugs.
      The only thing that i noticed was that I had to clean and silicone the side cam cover other than that I found the whole process rather simple.
      I'd give it a 4 out of 10 on the skill level scale.
      I hope this helps!
      Thanks Rich
