Valve Check Results Poll

Hey guys, most of us know there is a discrepency for unknown reasons between the North American valve check interval of 15k miles and the rest of the world which has a spec of 26.6k miles. I am interested in seeing some results of riders who have checked valves at both intervals and the results, so please pick one and let's see the truth about the 15k need (or even a 26k need to check)...

error on your info

My owners manual (canadian ) say 24k kilometres or 15k miles between inspections and since there's 1.6 km in a mile, that's equal btw...............

Thanks for starting this poll. I'm approaching the point of a first valve inspection. If you don't mind mark11, I would like to suggest to responders to post only first hand experience with your bike, not "I have a friend of a friend who has a cousin who's valves were xxxxx xxxxx" THANKS!

Agreed 100 percent!

Scooter it has been well established that the North American Versys owners manual and service manual call for 15k MILE valve checks and the rest of the world call for 26.6k MILE valve check intervals, no one knows why for sure, theories abound, however this is NOT a mile to kilometer conversion issue.

Wow, 89 people have read this thread and two votes. Guessing a lot of you haven't hit either valve check interval yet, which is surprising since the bike has been around for 2 full riding seasons already.

My bike is no where near 14K miles but if the Yamahas can go 26K, there is NO reason the Versys can't!!

Just passed 21K but the engine works fine.
Will check the valves once at 24K. Marc11, Thanks for the question.

I just checked my valves a couple of weeks ago at 30,000 kms and all were within spec except two exhaust valves which were a bit tight, but not enough to bother with. It's a fairly easy procedure if you follow the steps in the service manual. However, my torque wrench betrayed me (at least that's the story I'm sticking to!) and I ended up breaking not one but two valve cover bolts when I was putting things back together. Got to practice my extraction skills. All's well now.

What were the two tighter exhaust valve clearance at?
Specs: Exhaust 0.22 ∼ 0.31 mm (0.0087 ∼ 0.0122 in.)
Inlet 0.15 ∼ 0.21 mm (0.0059 ∼ 0.0083 in.)

Valve (cylinder head) cover bolts are torqued to only 87 in·lb (7.25 ft-lbs). They can be tightened by hand (with ratchet or wrench) if you're handy with tools... Snug them up gradually in sequence, then tighten slowly, getting a good feel for the bolt.

fwiw
the 07 service manual suggests the service intervals for the valves are 42,000 Km 26,00Miles, except for CA (presume thats California) where its 24,000 Km or 15,000 miles

so in the spirit of the OP I'll let you know probably next year.....
mebbe mid summer...
mebbe early autumn...

Im guessign the variation in CA/California is to comply with some legal diktat on emissions.

Interesting since the Versys wasn't sold in California until 2009.

This is true, because I am.

Cross-brand comparison might be moot, but my Honda ST1100 also had a habit of not having the valves go out of spec (about 70k miles before adjustments needed). At every scheduled valve check you'd feel a bit silly, "ah, fell for it again!", because the clearances would be fine.
But checking and finding all is OK is still a lot better than for example burning a too tight exhaust valve.

good point, I keep forgetting that the Versys wasn't sold in the Boonies until 2008

The two exhaust valves for cylinder 2 were somewhere between .15 and .20 mm (my feeler gauges go in .05 mm increments). My guess is closer to .20 because .15 was pretty loose. BTW, I didn't have any luck locating the marks through the site hole down near the crank, so I just made sure the cam lobes were pointing away from each other when I measured the clearances. Actually, what I should say is that when 1T appeared in the window the lobes were not pointing away from each other so I continued rotating the crank until they were. Invader, did you have any issue with that?

You better make sure you have at least 0.22 mm on those two tighter exhaust valves, which usually tend to get gradually tighter. You can use two smaller feeler gauge sizes together (0.12 + 0.10...). I haven't checked mine yet, only at 7000 kms. You did the right thing though by assuring the lobes of the corresponding piston were pointing away from each other.

Valve Clearance Measuring Position-
#1 Piston TDC at End of Compression Stroke (all #1 valves closed):
Inlet valve clearances of #1 piston, and Exhaust valve clearances of #1 piston.
#2 Piston TDC at End of Compression Stroke (all #2 valves closed):
Inlet valve clearances of #2 piston, and Exhaust valve clearances of #2 piston.

This seems counter-intuitive to me. I would expect valves to loosen over time, why do you say they will get tighter? Smart suggestion on the feeler gauges, BTW. Next time.

I've got 18k miles and havent done anything yet... I'm thinking I'll get mine checked somewhere around the 24k mile mark.
IS this something that should be taken to a mechanic, or is it doable for the home garage mechanic? I mean I have done all my own work till now, but have never checked valves before... though I am good at following directions.

Whatever pushes the valves down, wears away, so the valves get pushed down less which makes less of an opening, i.e. "tighter".

OK, that's what you mean by tighter. But doesn't it stand to reason that the wearing away will eventually result in the space between the cam lobe and bucket becoming greater, i.e., closer to spec? Must talk this over with some mechanic buddies of mine.
