I had to remove the head. I put it back together, lined up the timing marks spot on. Now my #3 header pipe is not getting hot, bike is sputtering.
I have spark.

What should I check? How should I check it?

 

Check comression on that cyl. Did you adjust the valves? If thats all good, maybe something in the carbs.

 

Well I figured it out. One of the exhaust valves on the #3 cylinder came off the retainers, It was just hanging open the whole time. I have no idea how it happened, I didnt mess with the valves at all.

 

no bent valves? Damn - that is luck. (Unless our engines are non-interference - anyone know?)

 

??? Looks good to me. How can I tell? will it be obvious?, cuz like I said upon inspection it looks good.

Question- If the valve were to have no shim at all, would that cause the valve retainers to come loose?
I took that cap thing off of that valve and pulled the parts out (springs, retainers) and it wasnt for a few more minutes that I realized that I didnt have the shim. I looked inside the head next to the valve and found it in there. I do remember that a few of the caps slipped out when I was removing the head for the first time.
Im not sure if it just fell off when I removed the springs, or if it just forgot to put it back in the first time the cap fell off

So, will no shim at all cause the valve retainers to come loose?
