OK, since I wrapped my exhaust I've noticed that I'm hearing more noise from the engine mechanicals and found one that makes me a little worried. Sounds like valve train and sounds like it is coming from the rocker box on the front cylinder. Could everyone/anyone take a listen and let me know if it seems normal?

Bike seems to run fine except it is a lot rough right around 1800rpm. Idles fine, starts quickly, front and rear pipes get to the same relative temperature. Basically just wondering if I have a bad lifter or bad rocker. Sounds like most shim over solid lifter engines when they are out of adjustment, since these engines have hydraulic lifters you can see my concern.

Have you made sure your header bolts are torqued properly?

Not since I put the header back on, need to buy a better inch/pound wrench and check them again. Very sure the front ones were correct at the time, but I did think I heard a small leak along with the metallic tapping sound.
