Q's about valve adjustment
By: Streeter Date: January 20, 2018, 2:25 pm
---------------------------------------------------------
I'm in the middle of a valve adjustment, and have a couple of
questions. Both of my intake valves are tight, but the
exhausts are fine. I've already adjusted one intake in the
past. In my experience with other bikes, usually the
exhausts need more attention. Is this common on the 690?
Just curious.
Also, while I have it apart, I'd like to check the rocker arms.
What do I check? The roller has a slight bit of
side-to-side movement, but does not move on it's axis. I
can't really think of anything else to check.
And just a comment: I bought two new shims at my local Harley
Davidson dealer. They are much more convenient than the KTM
dealer, had the shims in stock (for a Vee Rod) and two only cost
$10, which I thought was a good price. I think the shims are
the same size that my old Kawasaki ZRX 1100 used, too, but since
that bike was only imported for two years, none of the Kawasaki
dealers ever had them in stock.
Thanks!

Examine the rocker bearing carefully. Any play up or down is
the tell. If you have any replace them before selecting shims.
You didn't see any movement so I think you are in good shape.
As for getting tighter clearances all I can say is tight side of
the range isn't necessarily bad. Although I prefer the mid
range. If you know the reading / setting from the last check
compare it to the new check. If it got tighter then keep an eye
on it. It could mean that the valve is pounding it's way into
the seat bringing the stem closer to the rocker. This would be
not so good. My easy chair opinion is that is not happening.
My experience on this engine is once the engine has a few
thousand miles on it the clearances will not change unless the
rocker goes bad.
