I'm very happy to post my results to this! i was finally able to get to the variator after buying the right attachments to use a socket set with an impact drill. The stock kymco weights which seem to be 6 gram weights, had massive flat spots on them. i put a combination of 4 gram and 5 gram weights, and am able to go 10 miles per hour faster up my hill. i was only going between 10 and 25 mph, depending on if i had my girlfriend on with me or not, and am now going up to 30 mph up the hill.
Top speed has not been affected, i'm hitting up to 43-45 mph on flat ground without strong winds. I have noticed it takes a slightly longer time to reach top speed, pretty stoked on the overall results though. I've put around 6500 miles on the Agility 50, and this is the first time the weights have been changed. I reccomend others to at least take a look at your weights if you puts lots of miles on your scooter, it seems like they have the potential to get worn down fast...
Thanks for the input from everyone...
