Does the Pred require this? I haven't dealt with ATVs a WHOLE lot (much less four stroke ATVs) and I keep hearing about this. I don't remember seeing this in my owners manual!?

I've heard that you do not have to have them adjusted, like the hondas. If anyone else has heard differently, please let me know.

The clearence should still be checked periodically, it's much more labor intensive to make adjustments. The shims are between the valve stem and the cam followers (buckets) hence the cams will need to be removed to change shims.

I have over 60 hours on my machine... I know it's still running good based on running a Predator equipped identically to mine, except he had the Air Force box and I didn't. And we TIED. :)

So I wonder how often I should check the clearances?

Was at the Dealer yesterday and took my preddy in for its 6 month service while still under factory warrenty.

Service manager claims valve adjust is done at the 1 year service mark.

MY BIKE WAS WORKING GOOD BUT IT DID NOT REV QUICK AND SOMETIME DIDN'T PULL HARD.
WITH OUT ANYTHING TO COMPARE IT TOO. I ADJUSTED MY OWN VALVES OVER 6HRS OF PLAYING WITH LASH CAP AND CAM TIMING TO GET.007'' ON THE INTAKE AND .011'' ON THE EXHAUST THE BIKE PULLS LIKE MAD AND REV'S QUICKER. A NIGHT AND DAY DIFFERENTS. ONE OF MY VALVES WAS AT LESS AN .003'' THIS IS THE MUST IMPORTANT ADJUSTMENT TO AN ENGINE AS I REBIULD ENGINES AT A HEAVY DUTY DIESEL SHOP. THE IMPORTANT THING IS TO GET SOMEONE THAT WILL SPENT THE TIME DOING THIS JOB, AND NOT JUST SAID GO ENOUGH.

ROAD TEST AFTER AND LOVING IT, JUST PUT A 15/36T COMB. TO GO FOR SPEED

I had my tank off last night at work and decided to check the clearence. I have well over a hundred hours on it and the clearances were at .011 and .006. I never beat on my machine but it was run hard. I would say that unless your comfortable with doing it or your pred is running bad, I would leave them alone.
