4 hours sounds a bit too long
It can vary a little, some bikes dial in quicker than others.
I charge £40. That's it. It takes as long as it takes but at least you know what it's going to cost you.
That's for setting the TPS, balancing the throttles and then setting/balancing the mixture between cylinders.
and I would really reccomend one of JHP's eproms over the DP item. Loads better.
