Head hot enough to boil oil?

After a quick ride home yesterday from work (~2 miles) the top end on my bike was quite hot- I could hear boiling/popping sounds from inside. I've got my timing dialed in, and carbs jetted (a hair on the rich side) so I'm pretty sure it's not running hot due to a lean condition. Would the oil pressure from a stock pump be enough to cool a hot street build, or should I invest in an oil cooler? Is there a high-flow/pressure oil pump available as well?

Most of the late KZ bikes ran an oil cooler.  That doesn't mean they are necessary though.  I'm not sure about the shaft drive 1100 but with a lot of KZ engines you can install a later oil sump cover pan with the oil cooler takeoffs built in which makes installing a cooler easier.  That's what I did with my 750 anyway.  If you just ride your bike around in a sane fashion I'd skip the cooler.  As a mitigation against overheat abuse you can run synthetic oil which has a much higher vapor temperature compared to mineral oil.

Well that's just out of the question 

I just changed the oil with some Liqui-Moly 4T 15w50, I don't think its syntheic.

I'll see about the sump cover pan, finding a GPZ takeoff is turning into an expensive endeavor.

If your head is boiling oil? Something is too tight in that valve train!

I think I would get an infrared thermometer and find out for sure if something is getting too hot, and if so, what, before I began randomly replacing parts.

Do BS34 carbs provide adequate air/fuel flow for an 1170 engine with high lift cams?
RS36's+ would on my Christmas list.

This is very good advice.  Harbor freight sells one for $25.

They do seem to! I would not mind some RS36s, that would be a few Christmases worth though.

I'll swing by HF tomorrow and snag one.
