clockwise until the mark of the timing drive sprocket on the camshaft is at the
top, dead center, and the "T" symbol (or other mark) of the magneto flywheel aligns to the crankcase
mark.
When adjusting, loosen the lock nuts, adjust the bolts with
a valve-adjusting wrench when turned clockwise the valve
clearance decreases. And when turned counterclockwise
the valve clearance increases. Put a feeler gauge with specific
sizes between the valve and rocket to check for correct
clearance.
Take out the feeler gauge, tighten the lock nuts, and then inspect the valve clearance again.
Valve Clearance 0.08 ~ 0.12mm
Inspection and adjustment should be done in
cool conditions (below 35oC).
The crankshaft should corotate, or the exhaust port may not be adjusted.
Sometimes when tightening the lock nuts the clearance will change,
so it must be rechecked for the proper clearance.

what is the valve adjustment for the kazuma dingo 150cc ?

I noticed the small area upon assembling mine. I assumed that the steering shaft could be removed but didn't really look at it. Did you see if that is feasable?

My Dingo 150 is almost two years old and due for a valve adjustment. The valve cover is accessible enough but the steering rod sits directly in front of the cover. I have the cover loose but have not been able to get it off because of the steering rod. Can one of you tell me how to proceed in removing the cover? Thanks for all your help!

Spoke with John at Raceway and confirmed the steering shaft had to be moved in order to remove the valve cover. The good part is there are three slotted bolts on the bottom of the shaft with cotter pins. Remove those and ease the steering shaft up far enough to move it forward enough to remove the valve cover. The bad part is the nut on the steering shaft rung off while trying to get it off. I do drive this unit in salt marsh and get more corrosion then normal so suppose this nut had rusted frozen. It's a good thing I have two Dingo's!
