I've got an 04' Z400 that needs a new cam chain. While I have it appart, I was thinking of "fresh-in" her up a little bit with some new cams and a valve spring kit. It has no motor work done to it, and just a slip-on, jet kit, filter, and rev box for performance mods. I would like to throw in a set of hot cams, and was wondering if anyone knows if it will run fine with both cams instead of just the intake. I read some where that you should only do the intake for trail riding, but it didn't say why or what could happend if you used both. If anyone knows, could ya help me out? Thanks.
