What factor did u balance at? and what year type cranks are they?
Be very carefull handling them as is takes very little to untrue a unwelded kx crank :-)
very little crank pin diameter in webs {about 15mm in kx/ a cr5 has about 22mm and a thicker pin, this makes the kx crank very easy to move out of true
a pic to compare

One crank is from a 94 the other is from a 98.
I had a shop do the work so I'm not sure what the balance factor is. The shop I had it done at was pinsonnault racing and he only needed to know what piston I was going to run and in this case it was a 86mm wossner

The cranks look a bit unusual with the alignment holes { seen these on works crank /think alward25 has one }
none of my 89on cranks have holes
most shops use 50% factor /sometimes the scib the info between the webs,can be hard to see
think motorrad had his crank done at 60%
always nice to know what factor your running and how it feels in differant chasssic etc
good luck with the build,
