2005 valve settings the same as a 2006 klx 125

are they the correct valves? did u use grinding paste to seat them?
check online valve lengths

Here is some rule of thumb specs
intake should be between .003" to .005"
exhaust should be between .006" to .008"
When it's set right, it should feel like pushing a butter knife through butter right out of the fridge, also be aware that sometimes the lock nut can either tighten the clearance or loosen it.. This is a job to really take your time on

Please check further but I set them to:
(intake): 0,04-0,08 mm.
(exhaust): 0,08-0,12 mm
Both are set cold. Works for me.

Turn the throttle screw inward or outward as needed. Please rate my answer.

Inlet .003 - .005 inches
Exhaust .005 - .007 inches

I'm not 100% sure on this particular bike, but most late model hi-perf japanese bikes have shim adjustment. You can tell if you take the tappet cover off & the cams run straight ontop of the valves, If it's shims, you need to turn the motor until the cam lobes (pointy parts) face as opposite to the valves as possible (usually upwards) so the valve is completely shut, then use feeler gauges to me asure the gap between the valve tip & the cam. The valve springs can be compressed slightly (carefully) to let the shim on top (or underneath) the bucket be removed & replaced with the right thickness to give factory specs. Sometimes one shim from one valve can be used to make another valve correct, leaving less shims to buy. If not shims, should have a simple screw & locknut adjuster, same setup, just measure between valve & rocker, adjust to factory specs (or slightly smaller for more go)

.004 intake and.008 exhaust should work just fine.

The gearbox gets 10w40 motor oil.
