hi,can anyone tell me the valve clearances of my orion pro sieres 125?
should be set at;
intake 0.03
exhaust 0.04
That is way off dude unless you meant .003 and .004
2 thou = 0.0508mm (close enough to 0.05mm)
3 thou = 0.0762mm (close enough to 0.075mm)
4 thou = 0.1mm
They say that it is supposed to be between 2-3thou but with these china engines, Mack recons it is better to be between 3-4thou and heading towards 4thou for your exhaust.
