1978 KZ400 build help

Is this what you used for instructions?

I was using two different versions of the Haynes manual. That is far more clear thanks Ed!
Soooo did I do anything bad by removing that bolt and putting it back in?

It has a '75 muffler on it for some reason (bought it that way) and i am aware that different mufflers = different back pressures = different fuel air mixture but I cannot seem to decide, based on the symptoms of the original post if I need to rejet and if so, in what way.

I also have put some pod filters on and according to another post a guy jetted his with a 100 mains so I tried that and now I am way too rich.

Oh boy (why??) You now have lots of fiddling to do trying to get those CV carbs to work as well with pods as they did with the airbox.

I'm always amazed that anyone would make such a switch before getting the bike to run perfectly with the stock equipment since it adds a huge variable to the tuning process and precludes one from setting the stock baseline from which to measure performance gains or losses. Good luck and don't forget to write. :laugh: Ed

I loosened a bolt on the right side of the valve cover and pulled a 5 inch bolt horizontally out of the valve cover, then I removed the correct, giant bolt from the rear right side of the valve cover and watch the rocker arm drop back in to the engine. I managed to pull it back out and run the rod that holds it in place (the 5 inch one i removed) back through it and it seemed like it was all fine and good. However I must ask, did I mess up any settings, besides the gap, by pulling that long rod out and arbitrarily putting it back in?

Also when I was adjusting the gaps i really struggled to get my feeler gauge flat in the gap because I had to bend it a little bit to fit it in there. Any suggestions?
Thanks for all the help Nebr_Rex,
Adam

Valve adjustment is accomplished by the set screw and lock nut on the end off the rocker arm.
Yes, feeler gauge fitment is a real bear, especially the intake if memory serves me right.

Those bolts are a cam. As you turn them, it lifts or lowers the rocker arms. I'd go back to the air box, get it running right with the stock jetting, THEN F with the pods.

I knew I was going to disappoint y'all when I told you I had pods on... Especially Ed, I know you are not a big fan of pods but the good news is I kept the air box as per your advice in other threads so I can throw it back on once I give up on pods. However, I have all of winter to try and jet it right so maybe I will find a good mixture! Also, the bike was running pretty good before I put the pods on, just a bit rich so I was actually thinking that the pods would help that. Regardless, I will keep y'all posted as far as the perilous rejet process goes.

Wait swest are you saying that the way I put the cam back in could have been incorrect?

Thanks everybody,
Adam

All depends on which filters you use.
