Hi all,

I was doing the valve clearance check & adjustment on my ninja ex250 today. When i was doing intake valve adjustment, Found the adjusting screw was not moving! after many attempts....the edges of lock nut got damaged...somehow i was able to remove it from the cam...but while i was taking it out it dropped in the cam chain box (Chamber! - sorry I'm not sure what it called!!).
I am going to buy a magnetic-bit screw driver to find the nut in cam chain box! Is there any better way to get the nut out?
The 2nd question is: Since the valve clearance adjusting screw is not turning for the one of intake valve...What is best way to get this one done? (I already tried with bigger screw-driver but no luck and I don't want to damaged the head of the screw).

Please help.
Thanks in advance!

without disassembling the engine, magnets are going to be the way to go. To break the adjustment screw loose you're going to have to get creative. Maybe removing the rocker would be a good idea, and tap it with a hammer on a bench, use a penetrating oil of sorts, maybe even leave it container of motor oil. Lubrication and force are what's going to move it in the end.... Best of luck. Oh, and pics help.

Thanks spooph,
I have removed the lock nut completely and thats the nut was damaged and i was trying to put new nut which was made of steels and thats the reason magnet not going to work. The nut is actually got stucked between crank-case wall and the CAM chain at close to the crank-shaft.
Someone suggested to use cloth hanger wire to move it from there and then clow grabby to take it out. I am going to try that and see if that helps. I will try to take some picture if possible.
Thanks again,
Vmlp
