Engine and Bottom End / Determining rod length while bottom end is still together?

« on: May 13, 2015, 10:45:03 PM »

It has the Honda KA4 but I can't find any the reference or info on the last number which is a 5.  Or does it have any significance at all?

Sorry, I probably should have clarified that this is only the bottom end with no piston on the connecting rod.  So these checks don't work for me.  Was hoping someone just happened to have their top end off and could pull a quick measurement from those drum thingies to the top of a known short or long rod that I could compare to.

You can see in my info I guess (just joined a minute ago) as to what I am working with.  85 atc bottom end but am unsure of what was taken off the top end and while it should be a short rod maybe a custom build with a long rod?  Trying to track down what I need on the cheap and the sooner I know what I have to work with the better.  Hoping to reuse the crank/rod assembly (no discernible play up and down on rod) so if there was a measurement I could get while it is assembled that would be great! I will be doing a complete breakdown and reassembly with new bearings and seals throughout.  Already got a jug and head I will have to caliper it at work but while I cannot remember the advertised current bore I seem to remember that I would probably have to take it to a 68 1/2mm.  Already have an esr pipe (mid too low end) but have no idea how to proceed with a matching affordable carb (with appropriate jetting) and reed block intake setup.  Also I need all the plastics/mounting brackets but they are definitely more then I want to spend.  Wife says I need a hobby and I don't know anything about quads or two strokes but I like wrenching and learning so here I go :shame:.
