Hey nice Grab.
I can't for the life of me remember doing that seat.
The pipes should have only turned blue up near the head.
I would be a lil worried about how far back they blued. Maybe check your jetting,and go 1 or 2 steps richer than stock on both the pilot and main,and she how it runs.
There is a company in Oregon that makes this stuff called Blue Job.Google it.
It works really well for removeing the bluing from pipes, but if they are heavily blued, it will only work so well,if the chrome is damged.
Here is where my long useless list of stuff nobody cares about should go...
