Welcome,


Iridium plugs just last longer but may run a bit hot too.
It probably won't help with it being cold-blooded.
Most bikes are made to run a bit on the lean fuel side
to pass emissions tests.
A slight increase in idle pilot jet size might help
a bit. You could raise the carb slide needle one notch
by lowering the clip. That will richen the lower end
of the throttle range.
Air filter should fit well too and be serviced.
Be back in about an hour if you have more questions.
