Kawasaki lists the labor quantity for checking the lash on a C-14 at 3.2 hours. Yep, that is Earth hours, not Jupiter hours. My local dealer doubles that time and still can't make it although it is not a loser (below theoretical hourly rate but not actually losing money). The local dealer's rate is $75 / hour so that would be $480 at 6.4 hours not including materials used. They actually charge $500 as Marc said and another $90 if the cams have to be removed to actually change shims. So the job is profitable although not really generating the shop rate, just like most service jobs. Then again, it is more profitable to do larger jobs and sell labor in larger chunks; it is better for them to sell 6 hours of labor than it would be to sell 12 units of 1/2 hour labor at a time. There is just no way to get 16 units of 1/2 hour of labor into an 8 hour day- it would seem that it should work that way but it does not because of inefficiency moving between jobs, consulting a manual perhaps, procuring materials and parts, etc., etc. So on a larger job the service dept. will get closer to the actual stated labor rate than on a lot more small jobs.
The down side to the larger jobs is that it takes more skilled help to do those jobs just because they are more involved and require more knowledge and skill on the part of the technician. Not a problem for a competent, quality dealer but that is where the 'fly by night' dealers get into trouble.
That's what I'm trying to figure out. I know its a huge job, and I suspect the actual hourly rate would be outrageous if they charge the actual time it takes to do the job.
