I’m trying to get this 1978 XS750 running and I noticed burnt oil or residue from incomplete combustion in the cylinder #2 intake port. Cylinders #1 and #3 look nice and clean. I’ve attached photos for reference.
I admittedly tried to run the bike with pretty nasty carbs before starting the rebuild, and it surely caused misfire/backfire.
Compression is consistent across all 3 cylinders, squeezing 135psi-141psi.
Thanks for the input!
