Jetting, please help!!

[blasterkiller14]

I dont know much about jetting, except how to change them. I still use the stock jetting. I have a K&N Powerfilter, removed airbox lid and I plan to add a larger head pipe. What size jet should i use? My quad has crappy throttle response 1/4 to 3/4 throttle. Please help me.

Looks like you need to move your needle up a clip or two. Probably wanna go up a few sizes in jets. The best way to get the best jetting is trial and error. I know it sucks, but thats the best way. Look in the tech articles on the left side of the home page.
