Welp... Chrsitmas will be here in no time, soo..... now that i finally joined the bigger cc's crew, I'd like to ask a few questions..

I want the MOST power out my my 400ex as possible, from the mods i have listed, A slip-on HMF pipe K and N airfilter rejetted of course... What jetting should i run if i get a slip on? And I want to get a g-force axle and some tusk nerfs. Now i want to know I've read this many, many times that a slip on is about just as good as a full if your not planning on motor work right away.. And I ride in alot of straight feilds and stuff and the trails are mainly straight, and I'm looking to go back up to 20 inch tires, and go up a tooth in the front to a 15 tooth for a little more top end, but I was wondering, what will make more of a difference? 20 inch tires? or 15 tooth front sprocket?

both, you'll have good top end, but crappy accel.
