The dealer told me that the carbs (Mikuni) were rejetted . I have checked the jets, mains #90, pilots #40. float levels 17mm. Fuel mixture screws 2 1/2 turns out.The bike appears to run well but the tail pipes are sooty as are the plug bodies but not the center insulation.

I believe that's the stock configuration (someone please verify!) and not a rejetted configuration.
If your plugs have clean insulators (white or light tan) then it's pretty well stock.

My biggest problem is starting. When I picked the bike up from the dealer he explained that all the triples only fire when you take your finger off the starter button. To check this I removed the plugs, laid them on the head and cranked the motor, sure enough there was no spark until I stopped pressing the button. Is this normal?

No, that's not normal. The plugs should fire continuously when starting -- except for the first full revolution of the crankshaft while the igniter is figuring out the crankshaft position.
It's pretty improbable that there is some ignition defect preventing the ignition from firing while cranking, but I'd test that by hanging a spare sparkplug from a plug wire, grounding the big end to the chassis with a jumper cable and cranking the engine. (Be sure it's in neutral with the clutch pulled in!) There should be a spark while cranking.
It's also quite possible that your battery is weak and that while cranking the voltage is dropping to the point that the ignition can't fire.
Clean the battery terminals, charge the battery fully and try again. (It takes about 7 hours to fully charge a 14 Amp-Hour battery with a 2-Amp charger.) If charging the battery makes no difference then it may be time for a replacement.
