Title: 179 / 186 Valves
Post by: Effie C on August 18, 2002, 08:35:23 AM
Hello all
I can not find my manual on reds, so I thought I would bother everyone, does anyone know the valve sizes for a standard 179 motor

Thanks again
John M

Hi John
According to my book all early reds, 149 to the HR 186 had the same size valves,
Inlet, 1.490"
Exhaust, 1.275"
With a stem diameter of .341" for both inlet and exhaust.
Stem to guide clearance is .001 for inlet and .002 for exhaust.
Cheers
Tony
