I'm just wondering if anyone else has had an issue with their bike making a more distintive whining sound after they put chain and sprockets on. I did the -1 +2 vortex sprockets and 520XSO. I notice now that it seems to make a loud whining sound. I have the right amount of slack and the rear is aligned perfectly. Do you know what it could be?

Its common.

its typical for you to hear more noise coming from the drive chain after a conversion...

if you're sure you've done it correctly, I wouldnt worry about it.

it makes the noise because your contershaft spocket does not have the rubber isolator on it like the stock one.

make sure it is lubed very well

the front sprocket is now smaller if you’re doing -1 compared to the OEM sprocket , this changes the angle of the chain. so now the front part of the chain rubs / wears harshly against the upper hard plastic chain runner. this will be the really loud whining nose. the front sprocket will make more noise compared to the OEM which has the rubber damping either side. also obviously too tight would have make it noisy. but i did this conversation last week and the noise is louder than my race can with no baffles which is ridiculous. today i took a look at the chain runner and clearly you can see its contacting / wearing on the front of the upper runner (see pic). so i used a flexible dremel tool to get in there and cut it away. problem solved. (you can even see where the chain lube is gathering due to it contacting harshly and its worn down..) thats explains the very loud whining noise.
