Default Big bore build chirping on cold start
So I just did a FM 107 build, when it's freezing or below with a cold engine that's been sitting overnight my engine will chirp for a few seconds. Is this something I should look into. When it's warm out, no problem at all. I have manual releases and it seems like it comes from the left side of the bike

I don't start it just to start, I'm usually about to hop on it to ride. Like this morning when I was on my way to work. It was 29 degrees out, it chirped for a few seconds

Folks say it's most likely the Head gasket. I'm bringing it to my Indy to look further. Fuel Moto didn't build it, I did

Still haven't found the culprit, exhaust valves are completely dry, no oil found when I removed the exhaust. I didn't see an exhaust leak when testing with cigar smoke but I put my hand up near the front head and felt some air but then closer look and I have an oil leak coming from the rocker boxes. I think it was my fault, I went back in them and reused the gaskets. Can that cause a chirp? I got a James kit and will change them out

do a leak down when its cold,then leak it down when its hot (or warm).if its a ex valve,that`ll show it (seat leaking wouldn't show up as wet)

Are you sure it's not just a release that takes a few seconds to close?

I thought that might be it but if I start the bike without the cr's it still makes the chirp. It only makes it for all of 1 second.

Head gask?
Exhaust gask?
Hard to diagnose over the internet.
What solution/suggestion does the outfit you purchased from, offer?
