High idol in the hot weather

hi I only got my 2013 street triple on Friday I've done around 150 miles so far.
Today I got home from work around two pm. The bikes had its cover on in the garden.
So I've just gone to take it out for a ride and it's still worm and Idoling at 3'5 rpm
It's the a triumph thing ?

 

I did not no it had a idle knob lol.

 

Thanks for the input like I said it only had it 3 days and this is a first .

 

Also the bike got up to 25 mph in 3rd gear without me using the throttle .

so two hours in triumph and it's fixed.
I had a guy in the local garage fit my crash bars But The bolts where to long.
They had moved the throttle body over triumph said I'm lucky not to need a new one.
