Title: Cylinder maping....
Post by: JoePA on October 25, 2013, 11:27:09 AM

Not sure if thats the correct terminoligy but I have two cylinders that are ported but have no idea what they are ported for. How do I go about "mapping" out the cylinder to see what it's ported for?

You can measure also but I always use a wheel, I feel I am more accurate than measureing and using software to fiquire port timing
