ETR174 Posted November 13, 2014 Report Posted November 13, 2014 Just want to be clear, I have to measure the farthest and closest points that the piston comes to the head from the spark plug hole right? I was told it was a 4 mil but I just want to make sure. Quote
Larry's Shee Posted November 13, 2014 Report Posted November 13, 2014 Do the math, what do YOU come up with? So easy even this caveman has the answer. Quote
ETR174 Posted November 13, 2014 Author Report Posted November 13, 2014 I don't know anything about determining this Quote

trickedcarbine Posted November 14, 2014 Report Posted November 14, 2014 Some folks will talk shit, but you're ahead then a few fellas lately by at least using a decent way of measuring. Your numbers are fudged though. That only shows a 48mm stroke. Get the piston at BDC shove the caliper slide pin all the way down till it hits the piston. Now slowly rotate the flywheel till the piston comes all the way up. Even if it goes past TDC the caliper should stop at the highest point. Subtract the difference. You need to make sure the caliper isn't wiggling though. Quote
m671054 Posted November 14, 2014 Report Posted November 14, 2014 What??? I thought the pencil and tape measure was the way to measure 4mil cranks. Quote
#1JUANstunna Posted November 14, 2014 Report Posted November 14, 2014 Get the piston at BDC shove the caliper slide pin all the way down till it hits the piston.Zero your calipers if you can. Now slowly rotate the flywheel till the piston comes all the way up. Even if it goes past TDC the caliper should stop at the highest point. You need to make sure the caliper isn't wiggling though. This method will be simpler. Quote
#1JUANstunna Posted November 14, 2014 Report Posted November 14, 2014 No math needed, even the simplest simpleton should be able to figure it out. Quote
Deadbeat Posted November 14, 2014 Report Posted November 14, 2014 you own a super rare -6mm destroked banshee crank 1 Quote
ETR174 Posted November 14, 2014 Author Report Posted November 14, 2014 Yeah I figured it out in the shoutbox yesterday. TDC is 34mm and BDC is 88mm. I didnt know you just subtracted the numbers so its 54mm, stock. Turns out it is a Hot Rods crank, I thought it was a Wiseco. Quote
trickedcarbine Posted November 14, 2014 Report Posted November 14, 2014 That's still a good crank. Better then the Weisco. Is it welded? Quote
