the biceps are definately not prime movers during powercleans. If you're doing them properly they shouldn't be sore, the next day, or even tired after completing the set.
You need to pull the weight up smoothly to about half shin level, then really explode up with everything in your soul as fast as humanly possible, maybe faster.
at this point you just get under the bar bye letting it land on the front of your shoulders. Then stand up tall.
While this is a very simple synopsis of a complex movement, I suggest you hit up the Search feature (make sure your popup blocker is off).
You really shouldn't feel the biceps doing anything if you're able to accelerate the bar vertically onto your shoulders.
In the clean, form and acceleration are everything.
