Just checked my valves today at 505 miles. Intake good.... both
Exhaust pretty tight at .13 mm and .10 mm. Didn't expect to see such a
needed adjustment at 500 miles. How does this sound to anyone else? Is
this the "norm"????

500 mile valve adjustment

At 500 miles, all my valves were within spec (both exhaust
measured .178mm). I shimmed them to the
max clearance. At 5900 miles they tightened a bit but still in spec.
Again I shimmed to max clearance. Checked valves at 14350 miles -
valve clearance didn't change. (using rotella synthetic).
Are you sure engine was at top dead center and room temperature when
you measured?
It doesn't sound right.

Between 20,000 miles and 28,000 miles, my valves moved so little that I
did not do any shim swapping when I checked the valves. On my last valve
adjustment I did go to the next size shim in order to go back to the max
clearance again. It appears that, after 10,000 miles or so, KLR valves
don't move much or fast.

Alan,
IF you mean for the KLR... I'm not sure I'd recommend it for anything other than FULL-
TIME on ice. I used to ice-race many years ago, and I've had studs on car snow tires. On
pavement they sometimes would slide BIG TIME!!!
On the ice - I have done a wheelie across the Ottawa River near Hawksbury, Ontario when I
used to ice race, and that's about 3/8ths to 1/2 mile there, but I don't think I'd ride on the
road with studs. (Ice racing studs were/are sheet metal screws, not those tungsten studs
as in car tires.)
Good luck!
Fast Eddie
