Will I have to rejet from jetting on full Yoshi system when i put in my K&N and run a power lid or outerwears lid?

 

yes. because it will lean it out a little, unless you have it jetted very rich to start with

 

Stupid question but i am kind of new. What are the clips you all talk about? and is very easy to switch jets? I had it rejeted by the guy who put my pipe on. What size whould i put in to richen it upa little? Is it trial and error?

 

you might not have to deal with the clips on the needle. what it does is when you open the throttle it pulls the needle out of the main jet and lets more fuel in, the lower the clip is on the needle the more fuel goes through the jet. the needle is tapered so as it moves up it slowly lets in more fuel so it doesnt flood out on quick throttle responses
