400 powercore

[H400ex]

Hi to all, I just purchased a 2000 400ex yesterday. The guy i bought it from gave me a FMF powercore 4 slip on and dynojet kit. Should i put it on or should i buy another pipe. Its all stock now with a k&n filter only. If i put this pipe on what jetting do you guys recommend.Im 33 ft above sea level and its cold here 35 degrees.Thanks for any help.Mike

put the pipe on. i mean if you already have it throw it on there. for you jetting try like a 160 and check your pulg it may be a tad rich so go down a little i have an lrd and im runnin a 158 with my KN

Bolt it on, if it's free it's for me, I agree a 160 jet should work. Better to be rich than lean!

Put it on. I am very happy with my PC4..

I have the Powercore IV too, love the way it sounds, since he just gave it to you I'd go ahead and put it one, I'm about to install a K&N and Dynojet kit on my too, if I do mine first I'll let you know what I used
