I just bought a 03 z400 and I'm gonna put a new chain on it because it rattles pretty bad. I pulled the valve cover off and and lined the crank mark up but the cams don't line up the way my diagram shows. So I thought maybe it has aftermarket cams in it. Anyone have any ideas?
This is how its supposed to line up but mine lines up with intake cam #1 at top and exhaust cam with blank spot at top.

It looks like its on the wrong top dead center since what you said yours were are exactly the opposite ( 180 degres) of what it should be.

 

what markings are on the cams that you have?
if they're hot cams you will have a dot painted on it and you put the dot up and the 2 lines horizontal with the head
you wont have the link count like stock cams it doesnt work
Im not sure how web cams work for timing

 

or did you even check thats its on TDC....?

 

The cams don't have any other marks on them. And when you line up the mark on the generator its supposed to be at tdc. it's just wierd that the cams seem to be 180 out from what the pic shows.

 

Nevermind I'm an idoit I should have realized if its 180 out that the mark for the crank should still line up with the 3 and 2 marks on the cams. Thanks for the replies anyways

 

doesnt your bike have a cam chain tensioner?

 

yes it does
