Looks good Frank.
As far as the rear shocks, If it's anything like my ATV they will soften up once they get broke in. When i first got the ATV i couldn't even budge the rear or front springs. After a few off road trips they are about perfect now.
Power gets a little better once broke in as well. You need to find a god GY6 forum and see what those guys are doing. I've never fooled around with the weights in the CVT but from some of the videos and stuff i've read there is a big improvement once you get the right combination.
