new qlink xf200!

[Supermotarded]

Hey guys! Just bought a qlink in fair shape for $500! It runs and drives, has a few upgrades like a rear sprocket and a fabbed exhaust i made. I was wondering if anyone could point me in the right direction for carb jetting, and or tunning thr stock to run really rich. Also has anyone swapped hand controls? Mine seem to slip off haha.. So many questions! Im very tall as well and was wondering if anyone has found a rear shock/spring thats stiffer and maybe could raise the ride hight a lot more in the rear? I plan on getting a more dense oil for the fronts since they seem to be soft as a pillow. Any secrets to gain more power or things i should know? Sorry if im that annoying guy!
