i bought a new to me 05 yz450f after i sold my yz400f. after riding it around for the first time i was kind of dissapointed with the power. my 400 was built and very fast and im wanting a liitle more of that violent power of the 400 out of the 450. i did some searching and was wondering if i could swap a 04 cdi or get an aftermarket one. has anyone done this or have an experience with aftermarket cdi's. and i already put a full dr.d step system and a jd jet kit. thanks.

The CDI is where the problem is. Swap it for an '04, and you'll have an '04. The cams and virtually everything else was the same. An '06 unit should plug in, too, but the '04 is better suited to your cams.
