Using a new Teslong NTS 450 to have a look inside this Harley Panhead engine. I'm testing how well the Teslong borescope records and having a look for the first time of these original 1948/51 cylinders and heads.
Pretty impressed with the camera clarity. Thanks for posting. How happy are you with the good shape of what you saw! Would've sucked if you saw scoring on the cylinder walls or a bent valve right. Nice work
