Some bikes experience a hot start issue-there are a few threads on this.

What to look for is a lengthy list as there are lots of things that could cause this.

Check your coils...
Battery good?
When was the last time the valves were checked?
Check the fuel injectors too, one could be partially plugged...

40K miles.... Fuel pump, fuel injector screens, and kickstand switch.

By the way the fuel injectors are the same diameter as a Honda S2000. You can buy injector rebuild kits for Honda S2000 cheap.

How often do coils go bad?
Not often.
How often do coils go bad intermitently?
Almost never.
Check the fuel pump and filter.

No, there's no check engine light on a Gen 1 or 2....there is an FI light that will flash but that would indicate a fault....

I don't think you have a fault, just a blockage causing the bog...

I take it the bike ran poorly before you changed the plugs and if so, you had the stick coils off and you would have noticed any cracking or corrosion then most likely...

First thing that came to my mind too Six!
Classic symptoms of a crook fuel system.

You really need to check fuel pressure and fuel delivery rate as well, first things to check before pressure regulator and injectors.

(Top Tech Tip ..... never assume any components are 'OK', just start the checks at the start end of the system, pump first, then move along checking each component until you reach the end, in this case, the injectors.)
