cheese with that whine

i just swapped out my 530 15/42 set up for a 520 15/43, a driven/EK set up. ( thanks Brad ) i have noticed a whining noise now as i am getting on the throttle. seems to be rpm related based on its pitch going up and down with my throttle application. almost like a transmissoins gear whine. i do not recall hearing this with the old set up. i installed Gilles adjusters at the same time as the new gears so i believe my allignment is way more accurate than before.

anyone else note additional whining with the 520 setup. i do have a mod'd front sprocket cover as well.

tnx
