I assumed as they were doing his engine, he knew they were ok, and as they suggested balancing the crank they may have an idea what they are doing...but we can only speculate
The crank may be balanced, but is it still in balance with the flywheel/clutch etc as they've probably been off since the manufacturors done it, if they done the whole assembley rather than just the crank...
I wouldn't bother if your not going to do it right and balance it all. But on the other hand, you'll probably never notice it balanced or unbalanced! *edit* Unless you're RWD_Cossie_Will

I have had a number of people comment on how smooth the engines I have built run, but there you go...
