Chirping in rear Rocker Box
Went out for a ride on the 4th and it was freaking hot out. Started to develop a loud chirping sound like a bird from inside the rear rocker box. We pulled it all apart and inspected the rocker arms and end play, bushings, shafts, valve clearance, and an overall visual of everything and found nothing. Slapped it all back together and as soon as the temp reached 175° here comes the chirping. Bike runs fine (except for the bird in the box) no skipping, smoke or loss of compression. Has anyone seen or heard of anything similar??? This is a new one to me.

Problem solved
Pulled the tappet blocks and found the problem.
Looks like the rear cylinder exhaust lifter crapped out on me.
The SOB was pitted, roller was loose and had a groove worn into it.
Some minor metal chips in cam case, and it took out the finish on the cam lobes.
For all those chasing down a chirping in the rocker box, PLEASE check your rollers on your lifters.
I would have bet my paycheck and lost that the problem was in the rocker box.
Sound traveled up the pushrod and fooled the sh#t out of me.
