Auto decomp cam update

can i do this mod on my yz400f 1998 model? if so i am new to this upgrade and was wondering if anyone has a link or something so i can read about this mod. oh and is there any other easy mods for this bike?

Yes it does work on the 98 yz400. There is a pdf file that explains the install in detail. PM me your e-mail address and i will send it to you.
