EFI units don't need valve adjustments. It's computer controlled.

Sorry to disagree. Efi has nothing to do with valve adj. Computer cannot adj. a mechanical adj. like valves. Book recomends 1000 hrs. I recomend first 25 hrs. just to be sure it was right from the factory.

I have a 2007 Sportsman 800 EFI. It's low hours, like 28 and under 300 miles but I purchased it used so I am going through each and every maintenance item I can. I have the service manual and it states Valve Clearance check at 100 hours/620 miles or every 12 months.

I cannot find in the service manual how to adjust and what the clearance should be. I have found other incorrect information in the manual and I see a diagram stating it has hydrolic adjustment.

Therefore, I conlude and hope that you do not need Vlave Clearance checking.

i don't know they sound like there gonna blow up from the factory...i got a 3 year everything’s covered warranty on mine so im not worried out it. keep your filter clean and you should be good to go!! if they really have valves like cars that adjust hydraulically that’s cool!
