Piston I D

Wyrmrider said
looks like a small dome on the sparkplug side but also looks like there is a quench dome on the closed chamber side let me know I can't tell from pic
there is also a 191
if these have a quench dome and a small dome on the spark plug size they are one of several discontinued models- pity - they really worked
but you had to machine the dome to fit or adjust gasket thickness- the usual way
you can get the specs on the KB website- just click on the picture of the piston
mike the pistons for bore size
is the dome on the intake side higher than the one on the exhaust?

OK here's what I checked. The dome is flat across the top. The bottom of the skirt mics at 4.080 and just under the oil ring it mics at 4.050 which sounds like .040 over bore to a chart I found. But the confusing thing is the 060 up in side the piston that has 060 in it. couldn't find much on bore size on K B site. I will look a little more. but here are some more pics
