peterma:
My barrel just got a sleeve in and the compagni who did the job, took out the exhaust valves and I have tried to put the parts together again,
by placing the valves and rod on their marks, but the do not fully open and do not end up alike.

Anyone with some picturesof the correct installation.

The valves are alike and have some partnumbers, so canīt be placed wrong.

sandblaster:
Do you have pics looking into the exhaust port with the valves fully open and fully closed?

peterma:
This is my first KX500 so I donīt know much about it.

This is how it looks like, when the horizontal axle is fully out and the valves is placed on the marks.

peterma:
This is how it looks, when everything is placed on the marks and the horizontal axle is pressed fully in.

They look pretty close
The top picture looks almost spot on
The bottom one looks like it opening a little too much/ This could down to not having the side guide bush not inserted fully{tighten philips screw}

You need to get both valves lined up with exhaust subport with rod fully out /like top picture/ with side guide bush fully  inserted {one with philips screw]
With that done you kipps timing is Spot on
DONT TRY SETUP TIMING ON CLOSED POSITION

You the can fix the over closing issue, usually needs about 5mm added on to the allen key stop bolt {flwheel side}
 As soon as the exhaust sub port closes is where u want to be on close position {rod in }

its is possible to modify the kipps rod with a internally stopper {i use a little nut} and ignore the timing marks
its is also possible to modify ONE OF the valves  /make the kipps chamber work better /BUT I WOULD NOT WORRY ABOUT DOING THAT UNLESS U HAVE A BIG UNDERSTANDING OF HOW IT ALL WORKS :-D
heres a pic anyway /arrow point to the nut stopper on kipps rod
