Will i need to rejet

Have you rejetted for any of your other mods? Certainly your whole package should require rejetting. Adding a VF-3 reed setup isn't nearly the flow increase you got with the K&N and pipe. So the answer is....maybe....

BTW do you run the airbox lid? I was astounded the other day how much that restricts flow. Put it on to wash the quad and forgot to take it off - instantly fouled plugs, wouldn't run. Sorry, I digress.
