Consider this;
It's a dealership.
Some fairings have to come off, and the gas tank.
Brake fluid vacuumed out.
Rubber And steel hard lines need to come out.
New lines installed, fluid filled, brakes bled.
Oem top plate and top clamp removed.
Some come right off, others will fight you.
(I have done 2 ABM conversions on a Gen2, and a Gsxr1k.
I have also put ss lines on an ABS gsxr1k)
Reroute wiring harnesses.
Reinstall switches, mc's, put on new grips.
Put fairings back on.
Test everything, and test ride it.
So, to do it all in one 8 hour shift, especially if you havn't done one before, or put ss lines on an ABS bike, is not a bad first time at all.
Can he do it faster the next time? Sure.
But to say that the dealer is ripping someone off...nah, not for a first time on a job full of unknowns.
