I have an 07 400ex so far a i have a curtis Sparks full exhaust, Dyno Jet kit, K&N air filter and nerf bars. I want more power so what do you think my next move should be? thanks jason

i also dont plan on the boring it out i just want to keep it semi basic

sparks key and taking your choke out would probably be the best 2 things you can do along with a stage 1 hotcam. those are about the only things you are going to be able to do relatively cheap and easy. the rest you have to start boring or at the very least do some higher comp stuff. steve

have you looked up the 450r carb mod. what i heard so far is it can really wake up a trx400

i have read this too that is a good one to add to the list. the only reason i did not include this one is cause it does require some mods and such. steve
