If it is the same workshop that built your crank as the ones who jetted your bike i would double check the crank again as they were found out to lacking in know how .
Send the crank to a trusted mechanic for a check over , beter safe than sorry .

What are the simalarities between a 10 foot crockodile , an expired condom and a dodgy crank ?

You don't take chances with any of them !
