So I asked about plastiguage earlier, wasnt really happy with my measurments as far a s accurate. So, i used a mic, my crank measures at 2.125 pretty much on the dot. K1 stuff is nice, I dont have an inside mic so I measured them with my digital dial calipers whick I tested with my mic, and its spot on, I had it calibrated erlier this year at a machining shop in town. The rods measure 2.250 without a bearing in it, and each bearing half measures .062. If I add the .062 together it makes .124, that added to my inside measurement of 2.250 makes 2.374, now take that measurement minus the 2.125 i end up with .249. Is this more accurate than plastiguage because I hit .25 almost on the nut. Its a lot of math, and a bit of hassle, but without a dial bore gage its all I have for now. Would you guys consider this an accurate enough measurement, and run it or should I buy a dial bore gage?

or is my math totally messed up? I am not known for my math skills so Im just asking it this will work, dont rake me over the coals if Im wrong.

Your math is wrong

Crank 2.125
Rod big end 2.250
bearings .062 + .062=.124
SHould be Rod 2.250 - .124 = 2.126
Rod 2.126(with bearings in) - Crank 2.125 = .001 clearance
