2010 KTM 990 Adventure R - valve clearance check

I am little confused. Do I need to check the valve clearance on my 2010 KTM 990 Adventure R at the 600 mile (1,000 km) check or not? My owners manual tells me that the first valve clearance check should be done at the 15,000 km (9,321 miles) maintenance, my dealer gave me a print out for 2009 model year saying it should be done at the 600 mile check... Any ideas?
Thank you , Tomas

My dealer looked into it when I took my 2009 990R in for the first service (1000km). They told me that the valves do not need to be looked at until the 15,000km service.

It was a change in KTM service policy, initially the LC8 valves were checked at 600 miles but due to none needing to be adjusted, they moved the valve check to 9000 miles service.





EDIT: I WAS TOLD THIS BY A KTM TECH MACHANIC.

2009 - the first year that the 990 AdvR came out along with the newest style 990 Adv the service schedule changed so that you don't need the valves checked at 600 miles.

I love the bike, the power is amazing and it handles great. I will have more feed back in about a month, we are leaving next week "two up" on our 990 R for about 3,000 mile trip! Only one thing I wish for, and that is my girlfriends 38 inch inseam, that would make the balancing of a standing bike a little easier

Still, the questions remains, Is this new service interval applicable to earlier 950s?
If no changes were made to the valvetrain, they why wouldn't it be?

Inquiring minds want to know...

Valves

2009/10 990's have different heads than previous models and different maint schedules. It does not apply to 2008 and older.

That's correct. Different coolant passages.

If all that's different is the coolant passages, is this then the basis for the extended valve check interval?
That change seems like it'd have minimal effect on valve train wear. I'd think it would have to be something like changes to valve, valve seat, cam, cam follower, etc., materials, OR a change in the design of the valve train, to support a change in mileage checks if the reason wasn't simply that there weren't enough LC8s out of spec at 600 miles to continue justifying a check that early in its life.

I don't know for sure if the new interval applies retrospectively, but:

- how many pre 2009 bikes still haven't had a 600 mile service with valve check included?
- the heads and cams on the '09 on bike are different than all previous bikes (they use '07 superduke cams) so that may be the reason for the interval change rather than "no shims were ever changed at 600 miles". I would be surprised if anyone has objective evidence to support that theory- as opposed to just opinion.
